hi there, iv done a bit of searching around but basically i want some 16 deep dish bbs reps for my car, but i dont know what width and offset to go for to give it a cool sticking out look , without it scrubbing very much. the ones im looking at are 7js with an offset of et 20 through to et 38 what would be the best size to go for , and would i need stretched tyres? please help!!
