I thought the V8 Mustang in ITR would be a fine addition.
If anything, I figured that they would be significantly SLOWER than the top ITS cars, much less the ITR.
The lap times from this last weekend at Sebring would seem to bear that out.
My '94 Cobra Mustang that I race in BP is built well beyond ITR specifications.
(It has the larger Cobra 13in brakes and dyno'ed at over 300 RWH, 3195 lbs. w/driver)
My best lap time in Sunday's race was a 2:36.155
30 minutes earlier, Mike Flynn in a ITS BMW ran a 2:35.0
Tim Potter in a ITS RX7 ran a 2:35.7
