Yeah, I can see that you believe in having the suspension work rather than driving something that is stiff as a board. I haven't autocrossed in awhile, but I know that I had a tendency to set the car up to rotate around the tighter corners, and your's is definitely planting the front end and turning in. With the Koni / Eibach set up, the back end would tend to porpoise if the rebound dampening was set too loose, and there was any kind of dip or lip in the brake zone, so I'd have to crank it down a bit just to keep the back end from acting like a pogo stick. I've got the koni's on my OB track car now with bemco (non-progressive) springs, so it'll be interesting to be able to dial back off the rebound some and see if I can get my suspension to work similar to yours.

An "in the cabin" cam would be a cool addition next time, nice driving.

The "S" turns at 1:10 are flawless - excellent driving maximizing a well set up suspension.

Thanks for the complements. That bit at 1:10 was the funnest part of the course. The slight right turn going on to the pad was just enough to provide a Scandinavian filck action to setup the transition into that hard left. It took quite a bit of self control to NOT just bury my right foot and do the "S" drifting style, fun but not fast.

I've found that with 50/50 cars the balance in the turns has a definate speed/radius range. It's a compromise between pushing in the tight turns and getting loose on the big fast turns. I try to setup for balance in the average turn, about 100 ft radius. I was really fighting push until I cranked in the negative camber and zeroed the toe in the front. Took 3 seconds off my lap times!

I feel it is a little loose in the rear on the high speed esses shown at the very beginning so I may lower the rear ride height just a tiny bit and hope I don't get the push back.
