i just bought 18x7.5s 42mm offset to day no tires yet i would like to run 225-45 but they wont fit with the stock struts and i have read that the GC are the way to go i was wondering if i could run the 45s instead of the 40s if i put CG on the front, the rear has been lowered with the huge stereo i have back there so i would like to even it out also i live on a steep hill so when i pull up now i have to go very slow or my stock exhaust drags a little so i need adjustable sup. thank
