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).

With 22mm bars up front you need to be running at least 200s and maybe even 250s in the rear. I was running my four cylinder car with 180 rears on Carreras, no rear bar, stock tbars up front and a 23mm sway bar set at half way. You could run a rear bar and for go the heavy springs, this could lead to lifting the inside rear tire though on a tight course.

What tire pressure were you running? Run as much caster as you can get, set the rear to zero toe and run as much camber as you can get. Run your fron tire pressure lower in the front than in the rear. Also set the front shocks to full soft and see what happens. Are you running with a full tank of gas? Lose the passenger your car will handle very differently with a passenger. Make sure you can grease the poly bushings and do so before each event. Are you running a limited slip?
