confused on caster setting/s?!?!?!

[caindo]

i have the option of the following settings:

1/2 neg
1/4 neg
STD
1/4 pos
1/2 pos
3/4 pos
1 pos
1 1/4 pos



car is the 05 gto below. its lowered on coilovers in the front and lowering springs/shocks for the rear (all setup for autox roadracing). what caster setting do i want for the best cornering. car still is a DD on the freeway as well.

You want as much pos caster as you can get into the thing...... negitive is bad for handling only basicly makes it easier to steer. pos helps returnability and stability... so in a nutshell dial in as much pos as you can but keep it even side to side...

Our car is suppose to run 7-9 degrees of positive castor. Go with 8. Give it some negiitive camber also -1.0-1.5 at the most for the street and toe in to comp for the tire wear!
