Suspension Tuning Setup Advice Needed..., went from a swinger to a plow... Options

[cha914]

Ok, did the first autox with the new suspension on sunday, and I wasn't overly impressed with the results, but since I changed almost everything, I cant realy expect to have it right the first time.

So here goes, the car had very sluggish turn-in responce, and wanted to plow through every corner. I really couldn't even get it to rotate under trail braking. Here is the setup:

Koni Yellows all around
Poly bushings all around
Fully adj rear perches w/175lb springs
22mm solid torsion bars
22mm weltmeister front bar set full soft

Ride height = 4.75 up front and ~5.25 rear (measured to the donuts)
Camber = -1.5 up front -2 rear
Toe = 1/16th toe OUT up front and 1/16th toe IN rear

With the Koni's set to full hard the car seemed to improve a little, but not much. Also, the course was on a fairly slick parking lot, and I am running 2year old pirelli tires (205/50/15s with plenty of tread, just hard).

Finally, I want this car setup mostly for track driving, so I know autox performance is going to suffer some, but it seemed pretty poor overall yesterday (it was definately more fun with the ass up in the air sliding everywhere (IMG:style_emoticons/default/tongue.gif) now I want it to be fast)

Any suggestions on where to go from here, or what to try in the future (I know I need better tires).

I'd say it is the tires and a pretty good lack of grip. Since the suspension has been tightened up pretty well but you still have the same old tires that are slicker than snot on a glass door knob, they are now showing their true value. I'd say try some V700's or other new sticky tires and then you should have a good starting point. You could try shaving off most all of the tread on your old tires and there might be some soft rubber in there but I'd doubt it. Good luck.
