I watched the first half of your ITS race from the T1 grandstand with binoculars before I had to line up for my own race. I was VERY happy to see you driving the Corrado so competitively
I didn't realize you'd crashed until I spotted the unhappy car parked near victory circle (I took 2nd in ITC in the #23 Scirocco). I'm glad the damage wasn't too bad, but it looked to me like you really deserved to win it!
I think front tire loading is going to be the biggest issue with that car, no thanks to the huge front/rear weight difference, so I'm watching closely to see how you get past that hurdle. From my vantage point, I'd definitely say that you've done wonders so far
It did look to me like the front wheels were turned slightly more than optimal when steady-state in T1 (and in your pic of T10, compare with Chris' 944), so I'd guess that the rear could still take a slightly greater share of the cornering work. Not much you can do about the braking heat to the tire, though...
I'm new to the Hoosiers this year (coming from Goodyears), but have noticed that they get a bit slippery as tire pressures increase much above 42 psi (both 225/45-13 and 205/50-15). 40 psi is the recommended hot pressure that I've heard. They may have a relatively narrow pressure sweet-spot. In my application, low pressure (e.g., low 30s) doesn't seem as bad as high pressure (anything over about 41). They don't feel as good at low pressure, but at least they still have grip. Perhaps any apparent problem with tire temperatures on your car might really be due to transient rises in pressures above whatever is really optimal.
I've still got 3 running GTI VR6s in the driveway (as well as 2 ITC Sciroccos). The pressure is mounting to cull the heard, and I'll probably have to clean up before winter. Thus, my interest is not purely academic.
