Overview of Most Common Mods for BMW Street Racing Cars

BMW has always produced some of the most impressive and technologically advanced cars, which has made them a popular choice for street racing enthusiasts. If you’re looking to modify your BMW for street racing, you’ll need to focus on engine upgrades, suspension improvements, brake upgrades, exterior modifications, and safety equipment. In this article, we’ll explore these modifications in detail.

Most Popular Engine Upgrades

Engine modifications are among the most popular modifications for street racing cars, and BMWs are no exception. The most common engine upgrades for BMWs include adding a cold air intake, installing a performance exhaust system, and installing an ECU chip. A cold air intake can increase horsepower by up to 10%, while a performance exhaust system can increase horsepower by up to 20%. An ECU chip can provide a significant horsepower increase by optimizing the engine’s performance, fuel efficiency, and more.

Suspension & Handling Improvements

The suspension system of your BMW plays a significant role in handling and steering response. Upgrading your suspension system can improve your car’s stability and overall handling. Popular suspension modifications typically include lowering springs, coilovers, sway bars, and strut braces. Lowering springs and coilovers can lower the ride height of your car, lowering the center of gravity and improving handling. Sway bars can add stiffness to your car’s suspension, which helps minimize body roll. Strut braces can also add rigidity to the chassis, reducing flex and improving handling.

Brake Upgrades for Better Stopping Power

If you’re going to race your BMW, you need to be able to stop quickly and efficiently. Upgrading your brakes can not only improve stopping power but also reduce the risk of brake fade during high-speed driving. Popular brake upgrades for BMWs include upgrading the brake pads, rotors, and calipers. Brake pads and rotors with high-performance properties can withstand high temperatures without warping or fading. Upgrading the calipers can also improve the brake response, allowing you to stop quickly and efficiently.

Exterior & Interior Modifications

Exterior modifications are not only aesthetic but also serve a practical purpose for street racing cars. They can improve aerodynamics, reduce drag, and reduce weight. Popular exterior modifications for BMWs include adding a front splitter, rear spoiler, and lightweight wheels. Interior modifications, on the other hand, can improve your driving experience by adding comfort, safety, and convenience features. Popular interior modifications for BMWs include adding racing seats, a roll cage, and a racing harness.

Safety Equipment for Track Racing

Safety is always a top priority when street racing, which is why equipping your BMW with safety equipment is essential. Safety equipment typically includes a roll cage, racing harnesses, and a fire extinguisher. A roll cage can protect you in the event of a roll-over accident, while a racing harness can keep you securely in your seat during high-speed driving. A fire extinguisher can also be handy in case of a fire in the engine compartment.


Modifying your BMW for street racing is an exciting and rewarding experience. However, it’s essential to focus on modifications that will improve your car’s performance, handling, and safety. The modifications we’ve discussed in this article are among the most popular for street racing BMWs. Before making any modifications, make sure to research and consult with an experienced mechanic or tuner to ensure that the modifications are compatible with your specific BMW model and year.
