It sounds like your turning the wheels to quickly for the suspension to adjust. In doing so, you're breaking traction and then the car plows. Try turning the steering wheel slower (adjust turn-in point accordingly) so as to give time to the chassis to react and take its set. You have to work WITH your chassis/suspension, not against it.
It will feel like you are moving in slow motion in the car, that's normal when changing your technique. I have a hunch that it'll help. It will at the very least allow you time to get some feed back on the car's behavior. You should feel a build up of torque in the steering wheel as the lateral weight transfer occur.
That might be a little too technical to analyze while driving. Just think of slowing your steering input a bit and see if it helps.

I have SPL front A arms and change it to -3 degrees at the track. My street alignment is set at -1.5 degrees camber and 0 toe. The toe changes are minimal.
I've had it checked at both settings when I got it aligned and the toe change is nothing I can feel while driving the car.

I got the alignment as a favor, so I wasnt picky about getting a sheet. Adjusting the A-arms a half inch equals a half degree of camber. So, I have the street settings marked on my measuring tape and then thread them in a inch and a half, and then back out when I'm done.
When we changed it and put it on the rack it toe'd in slightly, I drove it and it felt fine. I took it back after I ran at the track to see if my street settings were good after adjusting at the track and it was back to normal.

Question: How much clearance do you have between the front tire and the upright/A-arm??
Can you stick your finger between them comfortably?
I want to do the same package on my stock 06 Grand Touring. I know the rears will fit fine, but had concerns about the fronts. As my GT wheels (18x9 30 ET) are pretty close to the upright...about one fingers space. I plan to add Hotchkis springs and sways soon, but that is all the mods planned today.

My old 17x9 +27's rubbed with a 275/40 tire and I had to run a 5mm spacer. From the small amount of street driving I have done with the new stuff, everything seems to be fine.

They indicated that if I returned from the track and dialed out the rear camber that it would affect my toe enough, on the street, that it'd wear my tires out within a few thousand miles.
I am much more concerned with the rear toe, and I don't touch it. I have mine set at -1.5 camber and a tiny bit of toe in. It's quite possible that you would in fact wear the tires out fast.
The front however, even with a lot of negative camber and toe does not wear that bad at all. I replace two sets of rear street tires before I have to get new fronts.
I think your safe messing with the front, and running -3 definitely has it's rewards!

That's a sick setup there, Brett!
I'm curious as to what kind of handling difference the wider wheel with similarly sized tire will bring at the track.
I'm trying to do the NASA VIR Feb event as the first event of 2008 ... you going to be there?

I'm considering getting the same 17x10 FN setup in either hyperblack or black with polished lip. Since NASA's performance touring category doesn't care about wheel width and only tire width I might as well get the most out of the 275 tire I plan to run.
BTW, the wheels are a few bucks cheaper at SPL. $212/wheel and only $9 to ship all 4 wheels.

I'm gonna do some time trials with Nasa this year and I didn't want the extra points since the tires were only a 50 tread wear. Thats why I got the Nittos and the widest rims I could fit.
