Towards the end of the course there was a big sweeper left turn going into a short chicane left right left followed by a straight. I took it a bit quicker on the sweeper this run so as to allow myself to just hold the throttle on the chicane. So I came into the chicane at a good speed, hit left, right, and then felt a bit of understeer and tried to correct by gently rolling off the throttle and the car jerked side to side and then sent me the OTHER way, tossing me off course...
Was this just some freak occurrence that's never happened to anyone? Am I that bad a driver? That happening really confused me.... I mean, I felt that that run the tires were really biting....I don't know if this was caused by me just not being used to the friction from those tire temps or something? Let me know what you guys think.
Thanks,
Dave
EDIT: Some details: Bridgestone Potenza RE-01R 245/45/17 all around, 37 psi rear, 39 psi front, stock suspension all around (until thursday!!!), 85?F ambient temp, 100 octane race fuel

I'm certainly not a veteran race driver here, but I've been "teaching" myself to drive the xi to the limit, which means changing what I know about driving a RWD platform. One thing I've determined is when you feel a bit of understeer, adding throttle can help with the xi. It's something very intuitive to drivers of front wheel drive cars, but a little wierd for RWD vets. I would assume you had all of the nanny controls deactivated?
