i just put on my new 17" allys on my subaru impreza non turbo and the rear left wheel rubs on the arch when i throw it right but when i throw it left it fine the rear right dont rub any ideas why one would rub and the other not it lowered 30 -40mm not sure what because it was done when i bought it and all the coating on the springs have come off so cant read whats on there! im thinking i might need harden shocks because it looks like the springs have been done but the shocks are standard. any ideas where i could get some????
