So, I have the car lowered with H&R springs, koni shocks and sway bars as well. Recently as i am pulling into gas stations or anyother place that has some kind of ramp and the car has to go up on it, even big speed bumps.. I hear squeaky sound, in the roof, and body of the car. Like the car is being twisted due to the ramp a bit and it is twisting the body and makes those sounds. I am not really happy with them as it is a lexus and not a tercel that should have all the sounds immaginable. Have others have that problem and anything i can do to resolve it ? Any help appreciated, i want it to be squeaky free Thanx.
