i just installed my new shocks and struts, the KYB GR-2's, for lowered cars, its the kit offered through Brother's. well the whole car rides great, as good as it did with the Tokico's that came off it, but now i get a rub on the rear right tire when i hit bumps at certain angles. its not horrible and i do have 315's with a 2.5 inch drop, noto to mention 3 x 12's weighing it down. but it did not rub before the new shocks? sounds simple enough right, it must be the shocks, but any ideas why? am i just going to have to buy another new set of shocks?
