..Saving lots of weight per wheel and unsprung weight (weight that is not support by the car's suspension such as the wheels, tyres, brake rotors and brake callipers). Reducing unsprung weight on your car is of the easiest way to improve your car's handling, braking, and acceleration. As general estimate, 1 lb of unsprung weight is equal to 10 lb of static weight (weight that is supported by the vehicle's suspension) And with every 10 lb lost from a car equals added 1 hp, reducing your unsprung weight can have a profound effect on performance...
According to the above, every lb lost in unsprung weight = 1 hp gain? that's - 0.454 kg = +0.75kw roughly speaking, every kilo lost in wheel's weight = 1.5 kw gain in power. True or False?
