They won't fit. Wrong offset for a FWD car and wrong bolt pattern. S10's have 5x4.75" bolt pattern and GP's have 5x115MM bolt pattern with positive offset. I've got a set of 16x7 Boyds Gotcha II's(I think that's the name off the top of my head) with tires for sale that'd fit the GP though.
I Don't Want To Buy Any, But The Truck Will Be Getting A Lot Of Body Work Done And Hopefully Painted So I Wasn't Going To Put The Wheels On. I Just Thought I'd Ride The Grand Prix In Style For A Little While But O Well Thanks Guys
