I think this car still likes to be driven with momentum more than drag-race style cornering, and I drive it that way. If you listen to my vid you can hear the tires talking in every corner, I'm on the line, and loading up the car. I think (hope) my 10-weekend old tires had something to do with that. Sorry, no video, the GoPro gave me fits all weekend. NT-01s are so easy to drive on right at the limit, I was practically drifting through some of the slower turns with throttle steering. That last Sunday session on the Nittos was stupid fun. At any rate I am convinced that tires>power at least with my car. Sucks because I missed second place by only 0.2 secs, and would have won a free tire from Hoosier. Not optimal, so that could have cost me a second or so. I finished the lap trying to shift the car by grabbing the top of the shifter turret through the shift boot. Oh yeah and in the middle of the Hoosier fast lap (fastest of the weekend) my shifter broke in two halfway through the lap coming into the bus stop. So for the last session Sunday afternoon I decided to remove the throttle stop and switch to NT-01s to see how they compared with more power (versus less power with the Hoosiers) I have to reduce peak power with the Hoosiers to stay class legal, hence the throttle stop.įunny that the NT-01s were only about 0.6 seconds slower, but in all fairness the slicks were pretty worn and should have been a lot faster. After racing on the slicks all day Saturday, and most of Sunday, they had been pretty much cycled out, and two of them had been flat spotted. Here is the story with the two lap times. Tires without throttle stop: Nitto NT-01 225/45/15, about 25% used. Tires with throttle stop: Hoosier 245/580-R15 Radial slicks R100 (medium), very used. Whp: 280 RWHP with throttle stop, 320 without throttle stop (both NASA certifications on a Dynojet) Weight with driver: 2650 lbs (weighed on tire scales) ![]() Lap Time: 1:45.1 (NASA AMB transponder timing system) - NT-01sīest theoretical lap: 1:13.2 (track record) ![]() Lap Time: 1:44.5 (NASA AMB transponder timing system) - Hoosiers
