road racing setup
1. Koni SAs
2. Adjustable rod/rod PHB
3. Strano 35mm front 22mm rear sway bar
4. Strano Springs (don't have these YET...)
5. Performance alignment (-1.5 camber, +4.5 castor, Zero Toe)
I have all but 4, which I will have soon, very happy w my set up.
Lots of good info on here (LS1tech), search around some, and read the stickies. Not busting your *****, but this has been covered many times.
BTW, I was told that the torque arm relocation would help with braking dive. Discuss this since it pertains to road racing.

Alot of guys go w toe out. That should help w turn in especially on lower speed auto-x. I haven't tried that but fear it will make the car chase grooves in the road worse. This has worked well 4 me on the road course and street. I haven't done any parking lot type, tight auto crosses since modding the car.

It has spring rates, alignment suggestions, and more!

The more positive caster you dial in helps with high speed stability. With the tire leaned back (upper ball joint behind the lower), initial steering wheel input has a lesser effect on changing the car's direction than if the ball joints were perfectly aligned. As you give more steering input, the turning effect has an exponential effect, that is the quicker steering input becomes. That's not to say the steering ratio changes, rather the effect of the given ratio changes. Subtle differece. The downside is you feel a little less feedback from the steering wheel and steering become "heavier". It taxes the hydraulics a little more.
Zero toe or toe out makes the steering input feel more precise and the car will react quicker. It lessens the effect, somewhat, from lots of caster. The downside is the car is a lot "twitchier", requiering a more focused driver.
Alignment specs, like spring rates and sway bar sizes boils down to personal preference and driving style. There is no set in stone spec for your specific application. You will have to experiment some with different settings in order to get it where you like it.
