I have recently installed a set of agx and prodrive spring. But there is some sound after the installation. Whenever I hit the bump or when the car is bouncing, the passenger rear suspension gives out some sound like gag, gag, gag. But, there is no sound when I am driving on a flat surface.
Also one more problem with my brake. This happens before I change my suspension. Whenever I press on the brake pedal hard, there is some "dock.. dock" sounds coming out from the car. However, there is no sounds when I brake in the reverse.
