okay so theres a guy selling some grand prix wheels. not sure what year alli know is they are 16". i just bought some 245/50/16 tires for 25 bucks thinking my friend had a set of IROCs he would let me borrow. they were stollen the day i got my tires. sooo i wanted to know if i would need some spacers for these or if they would fit. i wanted IROCs and still do, but with only 100 bucks i dont see it happeneing. thanks.
