Trailing Throttle Oversteer

This isn't just due to too much speed. In the skid pad elements of the event it was fairly easy to steer the car by the throttle pressure, I was just getting a little too much or too quick a rotation from throttle lift. If I had needed to slow down a lot I would have spun.
I could make the car understeer by pushing too fast thru a corner.
Now keep in mind we were on a dangerously slippery surface so all the handling traits were magnified. If the car handled like this on regular streets it would have been dangerous.
I was just hoping someone would give a quick couple of adjustments to get rid of some of this before Mineral Wells.
I think that I will probably add some toe and camber and see how that does at MW and then see about more drastic measures if needed.
I have tried not to spend any money on the S preferring to keep it as more of a street car. It is frustrating to have to delay the building of the Ultralite or the Z race car due to lack of space while I am waiting to begin construction on the new place. I am a full year behind schedule.

I'm not sure where I could've found more time to be honest -- I think the triangle might've been one. I was able to enter w/o brakes coming across the first apex but I may have taken it too wide trying to get around to the hypontenose(sp?) of the triangle leading to the fast-slalom.
I didn't get to meet Wildncrazy in person (I assume you were the yellow S out there - nice rims!). I didn't have too many problems w/ lift-throttle oversteer in the 2nd part of the day. I did during the 1st set when I lifted too much.
What I did have a problem with was getting power down in the corners. I think I maybe over-driving the corners...This was taken at corner 5. I don't like how I got that inside rear up so high...

Z06 guy launched his car leaving 2 huge streaks of rubber right out of the gate and pretty much did a big long tail slide all the way around the first loop, then going up towards the beginning of the triangle after the middle gate he nearly lost it. Made it through the slalom then started driving towards the freaking timing trailer instead of going through the box. They had to make him come to a complete stop until the instructor managed to get him back on course about 10 seconds later.
Didn't see the porsche guy that spun out or got lost and I don't think that "gal driving 10 mph" was my gf. It was her 4th autocross and she turned a 69 without any DNF's or cones so that's not bad, she just needs to be MUCH more liberal with the gas next time

While working corner 5, he tried to turn after EVERY cone lining up the entrance to my station (2nd U-turn). Finally exiting the turn, he just nailed the power. He had the instructor with him, but I don't think it was enough. I actually got scared for my life!
My friend in the RX8 has the same problem as your GF -- scared of using the gas. It took a year to finally get her to nail the gas hard, haha. She's afriad of going sideways
But she beat her husband Sunday, so she had a good time!

They are good B-stock cars in SCCA. They drive & feel like an S2k but with more practicality.
I just wondered how the 0-60 and

Well I guess I'll have to start all over on the trailing throttle issue. I am getting Gernby's JICs.
Now I'll have to learn how to dial that in

When my tires were cold, it was a real problem (mid-circle/entering the triangle) -- but once the tires warmed up, I didn't have too much of an issue with it.
