Well, the tires were amazing. I've never had the luck of racing with grip before, and these tires just stuck to the course. -and it was a good thing, since this course was much tighter than the previous event at this lot, with many 180 switchbacks and a mini-skidpad as well... I never encountered understeer through any turn at any speed-it actually threw me off at first since they gripped so well that I didn't know their limits... my new problem arose, though-I gripped so well that on such a tight course I couldn't hold on to anything and was flying all over the place! Anyone wanna donate some4 pt harnesses?? I loved it. I ran well, and could see from my video of my runs that I still made many mistakes that held me back from knocking off another 1/2 sec. or so from my best "clean" run. Either way I finshed 1st in STS of 7 drivers, and 3rd in PAX of 47. Tightest course I've ever driven, perfect test for the new (to me) tires, and a great end result!
