Engine Upgrades  

1. Turbo Inlet & Charge Pipe 

Before modifying any turbocharged BMW engine, it is highly recommended that owners replace their stock plastic turbocharger piping for an upgraded set. From the factory, many BMW engines are equipped with plastic components that become brittle and crack over time. Coupled with an increase in boost, these parts may fail at any given time. The turbo inlet and charge pipe in particular are two critical components to replace because it could quickly lead to failure should they crack and release pieces into the turbo or engine. 

Replacing these components will give owners piece of mind when increasing the power output of their engine. 

2. ECU Tuning 

The engine control unit (ECU) of your car is its brain. It modifies fuel, airflow, timing, boost, and fuel to maximize your BMW's horsepower and torque. BMWs are known to respond well to an ECU tune and acquire a significant amount of power because they are designed with performance in mind. 

Increasing your car's horsepower and torque production, maximizing fuel efficiency, and improving general driveability are the objectives of ECU tuning. Certain factory restrictions, including rev limiters and speed limiters, can also be removed with the use of ECU tweaking.

There are several “over-the-counter” tuning packages you can download from your smartphone or “plug & play” to your ECU or through the vehicle’s OBD II. Among the most popular tuning solutions are BootMod3 by ProTuning Freaks, JB4 by Burger Motorsports, MHD Flasher by MHD Tuning, and Dinan Performance Engine Software by, of course, Dinan. 

Choosing the right over-the-counter tuning platform for your BMW depends on your specific needs, technical expertise, and desired performance gains. The JB4 by Burger Motorsports is ideal for those seeking easy installation and significant power gains, while the MHD Flasher and Bootmod3 offer more advanced tuning capabilities for enthusiasts looking to dive deeper into customization. Each platform provides unique features and benefits, making them top choices for enhancing your BMW's performance. It’s not uncommon to see a 20-30% power increase over stock from a simple ECU tune on some BMW Engines. 

Additionally, these solutions offer different stages of ECU tuning to cater to various performance goals and preferences.

Stage 1: Basic Performance Enhancement

Stage 1 ECU tuning is designed for those looking to enhance their BMW's performance without making any hardware modifications. This stage focuses on recalibrating the ECU to optimize the engine’s air-fuel ratio, ignition timing, and boost pressure (for turbocharged models). The benefits of Stage 1 tuning include:

3. Cold Air Intake    

The stock intake system in a BMW engine is normally designed to strike a balance between comfort and efficiency. This is a manufacturer limitation intended for the general public. However, for serious automobile fans, this just limits your BMW's performance. It is recommended to upgrade to a high-performance cold-air intake because it allows more air into the forced induction engine, improving output.  

To improve performance and airflow, we recommend upgrading to a complete BMW intake system that eliminates the original air box. A cold air intake can also help improve fuel efficiency!

In our opinion, the best benefit of a performance air intake is the incredible sound you get from the engine. Performance air intakes sound better than stock intakes primarily due to their less restrictive design, increased airflow, and materials that enhance sound resonance. The combination of these factors leads to a louder, more aggressive, and sportier intake noise that many enthusiasts find appealing. This improved sound quality is often one of the key benefits, along with potential performance gains, that drivers seek when upgrading their air intake systems.

4. Turbocharger and Supercharger Kits  

If you are interested in getting serious power boosts, consider adding or upgrading a turbocharger or a supercharger to your BMW. Such forced induction systems operate by compressing air prior to its entry into the engine to allow more fuel to be burnt, and thus increase horsepower and torque.

• Turbochargers: To produce more power, the turbocharger relies on the exhaust gasses that otherwise would not be utilized. Turbochargers use 20 to 25 percent less gasoline compared to superchargers, data show. Hence, from an economic point of view, a turbocharger is a much better proposition.
• Superchargers: Superchargers are belt-driven from the engine, providing instant boost without lag. Because the supercharger draws rotational force straight from the crankshaft, you get additional power as soon as you push the pedal, unlike the turbocharger, which requires you to wait.

Remember that when increasing boost pressure with forced induction, it's crucial to upgrade the fuel system with supporting modifications to ensure adequate fuel delivery to meet the increased demand. Parts such as fuel pumps, injectors, and rails need to be upgraded to ensure the air to fuel ratio remains stable. 

5. Performance Exhaust System

Going for a performance exhaust system improves the power, sound and efficiency of the BMW when on the roads. These systems reduce back pressure and improve the exhaust flow of the engine, and so allow the engine to pull more air. 

The current market for BMW performance exhaust systems is diverse, with options ranging from subtle upgrades provided by BMW’s own M Performance line to more aggressive and powerful systems from aftermarket suppliers like Dinan, Fabspeed, ARMYTRIX, and AWE Tuning. Each of these manufacturers offers unique features and benefits, catering to the different needs and preferences of BMW enthusiasts. Whether you’re looking for a slight enhancement in sound and performance or a dramatic transformation, there is a performance exhaust system available to meet your requirements.

Suspension and Handling Upgrades  

1. Performance Suspension Kits

Suspension is one of the major components that require an upgrade if the goal is to improve the car handling and ride quality. Performance suspension kits usually include shock absorbers, struts and springs used to reduce the height of the car’s center of gravity and the extent of body roll. 

The market for BMW suspension kits is diverse, with options ranging from BMW’s own M Performance kits to high-performance solutions from Dinan, KW, H&R, and Fortune Auto. Each kit offers unique features and benefits tailored to enhance the driving experience by improving handling, ride quality, and vehicle dynamics. Whether you're looking for a slight improvement in performance or a comprehensive upgrade for track use, there is a suspension kit available to meet your needs.

Brands like Eibach, H&R, ST Suspensions, BC Racing, and Bilstein offer reliable and cost-effective options for enthusiasts looking to upgrade their suspension systems. These kits cater to various needs, from simple lowering springs to complete coilover setups, ensuring there's an option for every budget and performance requirement.

2. Upgraded Bushings 

Factory rubber bushings are designed to absorb a lot of vibrations and noise from the road, providing a comfortable and quiet ride. However, this absorption can also result in a spongy feeling during aggressive driving, as the rubber flexes under load.

Upgrading to polyurethane or solid bushings can greatly enhance a vehicle's handling response and feedback. Polyurethane bushings provide a good balance between improved performance and durability, making them a popular choice for both street and track use. Solid bushings, on the other hand, offer maximum performance at the cost of increased noise, vibrations, and harshness (NVH), making them only suitable for racing applications. By choosing the right type of bushing upgrade, drivers can tailor their car's suspension to better meet their driving needs and preferences.

Brake Upgrades

1. Performance Brake Pads and Rotors

Replacing standard brake pads and rotors with performance ones can dramatically improve the stopping ability and decrease brake fade. Performance pads have improved heat tolerance and increased friction, whereas slotted or drilled rotors provide enhanced cooling and minimized brake dust accumulation. 

The market for performance brake pads and rotors for BMWs offers a wide array of options to suit different driving styles and needs. Hawk Performance provides excellent street and light track options with their HPS and Ceramic lines, while StopTech and BimmerWorld offer robust rotor choices for enhanced braking performance. For those looking for OEM quality with enhanced performance, BMW’s own M Performance brake kits are an excellent, though more expensive, option. Whether you are upgrading for daily driving or preparing for track days, there are performance brake solutions available to meet your requirements.

Ceramic brake pads are a great choice for many drivers due to their low dust production, quiet operation, durability, consistent performance, and rotor-friendly nature. They are especially suitable for daily driving and situations where comfort and maintenance are priorities. However, for those engaged in high-performance or heavy-duty driving, other types of brake pads might be more appropriate.

2. Big Brake Kits

Big brake kits (BBKs) are popular upgrades for BMW enthusiasts looking to enhance their vehicle's braking performance, particularly for high-performance and track applications. These kits consist of larger, multi-piston calipers and extra-large rotors, giving improved braking efficiency and thermal management. Big brake kits are valuable, especially when driving a car in performance level or those cars meant for racing.

One of the most popular big brake kit options comes from BMW themselves. The M Performance brake kits offer larger pads, rotors, and calipers found on BMW’s more performance minded vehicle trims. These parts are easily interchangeable to their more economical counterparts but typically require a little bit of programming to update the vehicle’s electronics to the larger brake size.

For vehicle owners that have pushed their engine performance to the highest levels and are looking for the stopping power to match, after-market big brake kits from well known manufacturers like Brembo, Wilwood, AP Racing and StopTech offer the most stopping power with 4-6 piston and rotors to match. These kits can easily go for $3,000 to $7,000 a set so budget accordingly. 

3. Stainless Steel Brake Lines

Upgrading to stainless steel brake lines offers significant benefits in terms of brake performance, durability, safety, and aesthetics, making them a popular choice among car enthusiasts and performance drivers.

Rubber brake lines can expand under pressure, especially during heavy braking. This expansion reduces the force transmitted to the brake calipers, leading to a spongy brake pedal feel. Stainless steel lines resist expansion, ensuring that more of the pedal force is transmitted directly to the brakes, resulting in a firmer and more responsive pedal.

With less expansion, stainless steel lines provide more consistent braking performance, which is particularly beneficial during high-performance driving or on the track. The increased durability of stainless steel lines means they typically last longer than rubber lines, reducing the need for frequent replacements. The braided stainless steel sheath protects the inner Teflon core from road debris and other external damage, further ensuring the integrity of the brake system.

Wheels and Tires

1. Lightweight Wheels

One of, if not the most impactful upgrade for BMW’s – or any vehicle for that matter – is upgrading the wheels. Not only can wheels improve the look and feel of the vehicle, swapping to lightweight alloy or forged wheels can lower unsprung weight and thus increase acceleration, braking, and handling. It also lightens the vehicle weight and minimizes the amount of rotational inertia, which leads to faster responses to the directions provided by the steering wheels. 

When shopping for new wheels, having the right fitment is key to making sure your vehicle looks and handles exactly to your style and liking. One of the best ways of finding your right fitment is looking at what others are running on their vehicles for comparison. Sites like Fitment Industries offer a great tool and resource to view other’s fitment setups and find the right fitment for you.

2. Performance Tires 

Performance-oriented tires are specifically designed to provide superior grip on the road. They utilize specialized rubber compounds and tread patterns to maximize contact with the road surface, which enhances traction during acceleration, cornering, and braking. This results in more precise handling and improved overall vehicle dynamics.

The braking capabilities of performance tires are significantly better compared to standard all-season tires. The high-friction materials used in performance tires allow for shorter stopping distances, which is crucial for safety and performance, particularly in high-speed or emergency situations.

Performance tires are available in various types optimized for specific driving conditions, such as summer tires for warm weather and winter tires for cold weather. This specialization ensures that the tires perform optimally under the conditions they are designed for, providing maximum safety and performance.

For this reason, having two sets of wheels and tires—one for hot seasons (summer tires) and one for cold seasons (winter tires)—is essential for performance-minded BMW drivers. This approach ensures that your vehicle is always equipped with the optimal tire for the prevailing weather conditions, enhancing performance, safety, and driving enjoyment year-round. By investing in high-quality performance tires suited to each season, you can maximize the capabilities of your BMW and enjoy a superior driving experience.

Aerodynamics

1. Aerodynamic Kits

Downforce refers to the aerodynamic force that pushes a car’s tires onto the track or road as it moves forward. This increased grip allows for better traction, improved handling, and greater stability, especially at high speeds. Downforce is crucial for performance vehicles, particularly in racing, where maintaining control and speed through corners can make a significant difference.

Investing in aerodynamic components like front splitters, side skirts, rear diffusers, and spoilers can greatly improve the high-speed stability of your BMW. By reducing air resistance and increasing downforce, these parts enhance traction, control, and overall driving performance. For the best results, consider these upgrades as part of a comprehensive approach to improving your vehicle’s aerodynamics and performance.

2. Rear Wing

Rear wings are a critical component in enhancing the high-speed stability of performance vehicles like BMWs. By generating downforce, they improve traction, handling, and overall stability. However, the design and adjustment of the wing can significantly impact both downforce and drag, necessitating a careful balance to achieve the desired performance characteristics. Understanding these principles allows enthusiasts and racers to optimize their vehicles for specific driving conditions, whether it be for the track or everyday use.

While downforce is beneficial for handling, it comes with the trade-off of increased aerodynamic drag. This can reduce the car’s top speed and fuel efficiency. Finding the right balance between downforce and drag is essential. For track-focused setups, more downforce is usually preferred. For street use, a balance that provides stability without excessively increasing drag is ideal.

Interior and Driver Interface

1. Performance Seats

Upgrading to performance seats can significantly enhance driver comfort and support, especially during spirited driving. These seats are designed to offer better bolstering, materials that reduce sliding, and overall improved grip. Performance seats come with enhanced bolstering around the thighs, hips, and shoulders. This additional support helps keep the driver firmly in place during aggressive maneuvers, reducing fatigue and improving control.

Many performance seats are designed to be compatible with racing harnesses, which provide better restraint compared to standard seat belts. This can be particularly beneficial in track environments. Additionally, enhanced bolstering and sturdier construction can offer better protection in the event of a side impact.

Keep in mind however, most aftermarket performance seats don’t offer the same creature comforts such as heat, cooling, power adjustment and integrated airbags which is why many BMW owners usually opt to upgrade to BMW made seats from newer or performance minded trim levels. 

2. Steering Wheel Upgrades

A performance steering wheel can significantly enhance driver feedback and control, making it a popular upgrade among BMW enthusiasts. Performance steering wheels are designed to provide better tactile feedback, allowing the driver to feel more connected to the road. This sensitivity is crucial for precise driving, especially during spirited driving or on the track.

While the stock steering wheel size in most BMWs is designed for a balance of comfort and performance, a smaller diameter wheel (typically around 350mm) can provide more precise control and quicker steering response. For track use, a smaller diameter is often preferred, whereas for daily driving, a slightly larger wheel might offer better comfort.

Generally speaking, BMW steering wheels usually come in two flavors, the base model found on lower trim levels, and the M-Sport model which features a sportier, less bulky design. When looking to upgrade the steering wheel in your BMW, be sure to look for wheels that carry the same features available on your BMW. Create comforts such as the Cold Weather Package offers heated steering wheels for cold weather driving. These features can also be found on M-Sport and some aftermarket wheels. 

Paddle shifters are also something to consider when upgrading. While not all BMW’s come from the factory with paddle shifters, many are wired to accept the upgrade. Be sure to check your VIN and fuse box to determine if your vehicle is compatible. 

Upgrading to a performance steering wheel can greatly enhance your BMW driving experience by providing better feedback, improved control, and increased comfort. When choosing a performance steering wheel, consider factors such as diameter, grip thickness, material quality, and compatibility to ensure you select the best option for your needs. Balancing these elements will help you achieve a more engaging and enjoyable driving experience, whether on the track or the road.

Maintenance and Supporting Modifications

1. Cooling System Upgrades

High-performance driving generates more heat, so upgrading the cooling system is crucial. Consider larger radiators, intercoolers (for forced induction systems), and oil coolers to keep temperatures in check.

2. Clutch and Transmission

Upgrading the clutch and transmission components can handle the increased power from other performance modifications. Consider a performance clutch kit, short-throw shifter, and stronger transmission mounts for better power delivery and shifting experience.

3. Differential Upgrades

Upgrading to a limited-slip differential (LSD) can improve traction and handling, especially during aggressive driving. An LSD distributes power more evenly between the wheels, reducing wheel spin and improving cornering performance.
