It was something of a bummer to not make it but we were pretty close. Everyone involved put in a serious college try but it was just not to be. For instance, not 15 hours before it turned a wheel on track I had the engine torn down to the block replacing head gaskets and so on whilst tracking down a little water leak. If I had not gotten the flu I think we'd have made the race, but woulda shoulda coulda. Straight out of the box the car did great. We will make it in 2010.
Our alignment specs that we started with were:
Front
-1.7 degrees negative camber
+5 positive caster
Zero toe
Rack on inner steering hole
Once we collected some data we found the car was toed out at ride height after it'd been on track and settled. Too much camber for the front too.
Rear
-1.5 degrees negative camber
+7 positive caster
1/16th inch toe in
The rear felt pretty good, very nice and just needed to drop some camber to get it right. I like the 400 lbs springs in the rear, they were about right. So all we need to do is decamber a bit and adjust shocks, for the rear.
On the front we want to try a tad bit faster rack, a slightly different rack mounting position, less camber, and see how that strikes us.
As for tires and temps we're running ho hos and started them about 30 psi all around. With the light driving we did we didn't get them up to temp or pressure, but we weren't too far off either. Pressures can be fiddled with a whole lot more as well but until we get the front behaving exactly like we want all this info is gross data and just simple collection at this point.
Just got in the good 4.22 gear ratio for the box. Data shows we need that - the acceleration rate is insane in the car as the Traqmate data shows. You can't really feel it while driving because on track you just never know how fast you're going, plus, this is a new car, open top, new noises and so on. But on the data traces the car pulls very linearly from 80mph to 140mph, something that we're not used to experiencing. My Z can claw its way to 137 mph at Daytona, but this thing goes to a rev limited 140mph in about 1/2 the straight at VIR. The velocity curve doesn't roll over flat like my Z!
