like the title says, i finally ordered my lowering springs for my 06 gs430. ill be doing the install myself and it seems pretty straight forward but ill look at some write ups on the rear portion for the drop. the rims ill be sitting on are niche milan 20x8.5 fr 245/30/20 and 20x10 rr 275/30/20 offset is 35 front and rear is 40mm. ive been told i shouldnt rub in the rear but im also considering getting the rear fender rolled either way. what do you guys think on rear fenders? rolled or leave it alone? thanks!
