Whats up all. I just bought a 2003 Extreme and was surfing for advice on parts and ran across this web site. Lots of good info here. Im stoked at what can be shared and learned. I also own a 1997 Grand Prix GTP that has and is being built. It's a 12.5 car right now and I do all my own work so I should be able to help with Technical questions. Lookin forward to chatin. Later!
