Need help again

Hey guys, so a couple of months ago I bought a brand new GT. The dealer installed aftermarket wheels and said they installed the GT500 suspension. Now 3 months later my car is all chipped up, really bad(I'll post pics tomorrow) they are all along the bottom of the car and it's worse then my 01 GT was. Is this normal for my car to chip this easily? I took it back and they won't do anything for it.

Also I'm really starting to wonder if they really did put that suspension on the car, it seems like it rides pretty high. How can I check to be sure? I looked underneath and there are stickers on the springs with numbers on them, is there anyway I can look from that? I also found out that a guy came in with a Shelby with a aftermarket suspension package had them install it, then they took his old parts and put it on my car. I'm a little pissed off that I bought a brand new car with a used suspension on it. Don't you guys agree? What should I do?

Thanks for any help. :SNSign:

I took the car in to get some gauges put in and I asked the tech that installed the suspension on the car and thats what he said.

Thanks.

It wasn't my idea for them to put it on the car, they had already done it and it's a long story why I ended up with this one instead of the one I ordered. I got to excited when I got it that I didn't think about the GT500 being heavier and the suspension not working as good. But oh well.
