Re: What is Control Arm Bushings and Motor Mounts Do ? (kcying)
polyurethane motor mounts will improve engine response when you get on the throttle. instead of getting on the gas, having a slight delay and then moving, it will be a more direct feedback with stiffer motor mounts.
control arm bushings...lower or upper? polyurethane or rubber? anyway you get harder bushings for the suspension to make the suspension more rigid. Poly Bushings are sort of a PITA though because they tend to fail alot and they tend to make some noise. rubber bushings are what are on the car already.
