I bought it! Literally, just bought it today!
Put 700# springs up front, with 450# in rear. Rides excellent for my commute now. The heavier fronts seemed to balance out the chassis at 60+.
Motion ratios are way different and Tony isn't going to autocross it like that. Should understeer pretty good. Also the sway bars are pretty much opposite. This winter I am thinking on going to 700 front with 600 rear. Keeps the same balance the same as what I have now on paper just stiffer. I will have more info coming on that soon in my build thread. Doing a good look at our suspension. Stay tuned for good info.
Installed bilstein coilovers and spent way too much time with initial ride height settings. If anyone is interested in CS adjustable dampers and RB springs, I have a used set available.
