Customizing your car’s performance in CMS 2021 is essential for success on the track. Here’s a detailed guide to help you increase tuning.

Engine Performance

Intake and Exhaust: Replace the stock intake and exhaust systems with performance parts to improve airflow and reduce backpressure.
Turbocharger/Supercharger: Install a turbocharger or supercharger to increase boost pressure and horsepower.
Engine Block and Head: Upgrade the engine block and head to handle higher compression ratios and boost levels.
Fuel System: Install a larger fuel pump and injectors to ensure adequate fuel delivery for increased engine performance.

Driveline and Suspension

Transmission: Replace the stock transmission with a performance unit that can handle higher torque and faster shifting.
Differential: Upgrade the differential to improve traction and control under acceleration.
Suspension: Replace the stock suspension with performance coil-overs or struts to improve handling and stability.
Brakes: Upgrade the brake pads, rotors, and calipers to increase stopping power.


Front Splitter: Install a front splitter to generate downforce and reduce drag.
Rear Wing: Add a rear wing or spoiler to create downforce at high speeds.
Side Skirts: Install side skirts to improve airflow around the car and reduce turbulence.

Weight Reduction
