Hey Guys, Can anybody refer me to a shop where I can get a lowering kit for my 2004 Grand Prix Comp G ? as well as refering me to a shop that would change them as well...What would be the max lowering I can go ?, I dont drive the car in the winter so I dont worry about snow and crap, I also dont have passengers in the rear seat, so im looking for low as long as im rubbing the fenders. I have 18" all around. I live in Toronto Canada. Thanx.
