"The first few runs were merely tire-spinning warmup laps that had nothing to do with getting a number. I had wheelspin from the middle to the top of 1st, 2nd and 3rd gears. (I'm sure you can calculate those speeds.) Once the tires heated up and got stickier, it was nearly impossible to launch the car for the following reasons: Bog 1) The car has no torque below 4,000 rpm as it now has no supercharger. Bog 2) The tires (now heated) resist spinning more than the stock tire. Bog 3) 1st gear is so tall (shifts to 2nd over 60 mph), the sticky tires pull the revs down until the turbos light at 5,000 rpm [bog]. The one time out of 12 I managed to slip the clutch almost just right, it got a decent sub-2-second 0-30 time. As long as I didn't botch a shift, the rest of the run was pretty uneventful. Yeah, it's fast, and you've got to keep your eye on the tach because I was told to shift at 6,500-7,000 rpm. That leaves about 1,500-2,000 rpm at wide-open throttle. The tires now did their job maintaining traction at wide-open throttle in each gear. It turns out the car crossed the finish line just before grabbing 4th gear at 137 mph. As is the case in any stock GT, the driving position is superb and the shifter is light and accommodates quick shifting. There was some turbulence from (I'm guessing here) 100-140 mph where the hood vibrated, but that might've been the drag strip surface, too."
The braking distances didn't show any signs of a trend up or down. In order: 106, 107, 105, 107, 103, 104, 104, 104, etc. so I stopped there. Zero dive, but some shuddering as the tires dug in their euphemistic heels. Straight as an arrow with a hard, hard pedal.
These tires weren't on speaking terms with the recently resurfaced pavement. Understeer was the limiting factor in both the slalom and skid pad. Even in the middle of a dozen slalom runs (when one would expect the tires to have met the correct temp), I still had zigzag back to the start line to maintain enough heat in the Hoosiers to get a 70-mph run. Still, it understeered. Also, the stiff-short sidewalls didn't absorb any of the imperfections in the surface and the suspension had to do all of it. I've never heard a GT's suspension clickity-clack like this one did. Reminded me of a 360 Challenge Stradale. Also like the 360 C.S., steering was thankfully quick, precise and light in a good way. Clutch pedal became reluctant to return near the end of the slalom runs. One might've expected this car to perform better than a stock GT, but even our rigorous testing doesn't come close enough to the minimum amount of abuse these tires require to work well.
