My Corvette(s): 1996 LT4, Z51 CE Coupe -- (sold to Hrtbeat1)
There are two different offsets for the GS and the ZR1 rear wheels... The GS wheels barely stick out, while a set of ZR1 wheels would stick way out... chevy actually attached the first few GS's rear fender flares with double sided tape for owners who may not like them... this is because the car actually looks ok without the flares, even with the big tires... If you decide on the bigger rear wheels on a stock vette, get the GS offset wheels.
