Insite, what kind of settings are you using at the track?
tire pressures
sway bar settings
ride heights
shock stiffness
camber/toe
I'm trying to get my ride heights dialed in now. I think I was hitting my bump stops at my last autocross. I'd be curious to see how you've got your car setup for the track.

tire pressures are 38 hot (or 38 cold at autox) front and rear. front gt3 sway is full soft. rear h&R sway is full soft on one side, full stiff on the other. shocks at the track were set at 31F, 30R. front camber is -1.5; rear is -2.0. front toe is zero and rear toe is VERY slight toe in. have to get back to you on the ride heights, but the rear is 1/2" higher than the front. it REALLY performs like this.

Thanks Insite. I appreciate the feedback.
At my last autocross I think I was running too low in the front - about 24.5" from the ground to the fender, measuring through the center of the wheel. I've raised it up about an inch now.
Your toe settings seem to be pretty typical for our cars and that's how I'm running. I was at -2.5 degrees of camber in the front though and -3.0 in the back. I couldn't stand the noise from the camber plates though, so I've pulled those and will align the car closer to what you have, -1.5 in the front and -2.0 to -2.2 in the rear.
I'll try running higher tire pressures next time as I was quite a bit lower - 32 psi front and 34 psi rear.

Kirk, educate me as to what the noise sounded like and how I would remove the camber plates... I'm not even sure I know what they are on my ksports (sometimes I feel like a total idiot).

You don't really need to worry about it Randall. I'd bet the camber plates on your car are fine. The ones I got just had a bad batch of spherical bearings in them. I knew they were bad because they'd make a loud rattling noise over any kind of road irregularity. My daily driver has camber plates too and over the last six years I've been driving it I've never had so much noise.
The camber plate though on your KSports is the part at the top that locates the top of the shock and the spring. It has a couple of bolts in it to allow you to adjust camber.
