Jared... Welcome. (I recognize you from motorgeek).
Stephen has been helping me set up my ITB Coupe and I ran it for the first time this past weekend at Mid-Ohio with the new "type-Blethen" suspension. Basically, I removed the front sway bar, kept my rear bar (adapted from another Audi) and switched the spring rates. I was running 450 in the front and 350 in the rears.
Upon Stephen's suggestion, I went to 700# in the front (with no sway) and put the 450's in the rear. Along with a good alignment and some custom valved Bilstein's, it was an instant transformation. I don't have the greatest of tires (Victoracers from a few seasons ago) and I still picked up over three seconds on my fastest lap times from last year. I was impressed. I was happy to trophy for the first time and the car felt great.
The springs help the roll stiffness while the lack of swaybar helps the suspension "droop" and keep more contact with the track...at least that's my theory. The corner weights Stephen mentioned are around the same for my car and my car is still pushing a bit. I played with brake bias and tire pressures in efforts to get the back end to rotate, but that only worked a little.
I'm anxious to try a quaiffe in my transmission and get some custom camber plates fitted as well. We'll have to see how adding the plates affects the suspension that I just changed. Should be fun.
I found out this weekend that we can run 15" rims on our cars now (didn't know that), so I might be shopping to see if I can find a nice light set that are within budget. We'll have to see.
Stephen... as far as a "stay rod"... how would that benefit us? I've heard of people adding a chain / rod with joints to the front of the engine to keep it from rocking front to back. Mine has a poly mount on there now.
