Just my .02, but If I were you, I'd try to check into the history of your car before you change it around any. Might be an actual pace car that was used at a Indy car race or something like that (we've had one guy find out his car was used at Indy for a caution car). It would be a shame to modify a car with that kind of history, as well as potentially lowering the value of your ride. I'm not saying don't jump, just advising look before you leap.
Anyway, that's a sharp car man!
