When rebuilding the shocks for that car, Moton was given the spring rates and the corner weights. I don't know if they altered their normal rebuild process to suit those factors. The plots can be seen here: http://s253.photobucket.com/user/Fas...20Dyno%20Plots

That's awesome. So you picked up a fully prepped pro racer! One of my track buddies did that with a 997.1 Carrera. The thing is a beast. Formerly raced in GS as well; can't remember which team. Got an absolutely killer deal. That's the way to go.

I've been at the track 40-50 days a year with the car and I have a pro shop on it all the time, so that's most of the reason why. It's actually very reliable in the conventional sense.

Other than the expense, it's been a great experience, and a route I recommend to anyone who is really serious about tracking a car. As we all say (and either know or learn later), it's cheaper to buy than it is to build.

So as to stay on topic, here's a video of the car with its 1600# front springs and 1½" front bar shot at the Glen during aero testing - not much roll here! lol BTW, it's running the AP Competition Kit - those brakes are very capable.
