I hit 130 mph on the front straight at California Speedway in Fontana last March... it was rock stable and just seemed to keep settling down. I had to back off... that wall at turn one didn't look to forgiving and I was on Pilot Sport All Season tires...
That being said, I could easily carry 110 to 115 through turn one and two and the car was not even being pushed out. All that on street tires with all weather tread...
I can't wait to get the performance rubber on this thing.
