Huh? Nope.i believe the offset is the tires wall width...so if ur car isnt lowered and u order 17" rims with a 40 mm or lower offset..the car will look alittle higher than normal off the wheel. hence..lowering springs.
i'm planning on getting 17's in the spring and going to try to keep the 45 mm offset. i wanna keep the car as bone stock as possible. just rims for me
