How to modify the car will speed up.

Speed increase and acceleration involve many aspects.

First, lose weight. Reduce the weight of the building owner and the body (the common way is to replace the carbon fiber cover and the tail cover. If it is overhauled, it is necessary to remove the rear seat, replace the anti-roll frame, replace the door with carbon fiber, and the interior can be removed. )

Second, change the hub. Lightweight forged wheels can be selected.

Third, change the power system. Air intake, full exhaust, ECU brush (the negative impact is that the engine life is reduced, and the main turbine is not supported. And I remember that BMW's turbines are all single turbine and double scroll tubes), changing burners and cooling systems (oil cooling, water cooling, etc.). )

Fourth, due to the strengthening of power, the corresponding rims, tires, brakes, shock absorbers, etc. It must be upgraded, and safety should be considered. Hubs and brakes must be changed, the brakes can be changed from the first six to the last four, the wheels can be 20 inches, and the tire width should be mastered.

It is estimated that 0- 100 can enter 4.5.
