All I can say is that after a couple of years running on a very tight track, My setup is basically "exactly" what IntialD was saying.

I put close to 2.5 to 3 Deg of rear toe which in someways allows the car to turn in quicker in both directions do to the amount of corners involved on the track.

Secondly, I also place the caster as stated by "D" for what appears to be a quicker response.

Third, I'm sure someone here has posted or seen the trick with removing approimately 3mm off the front end for a shorter wheelbase.

Lastly, I also do not run sway bars front or rear and the car handles like a gem , letting the shocks do all the work.

Right or wrong in theory it works very well at our track.

When we go to the bigger tracks in California, and Vegas it's a whole different story and the Car is completely different.

Just my two cents, and yes thats probably all it's worth LOL !!!
