As with most things in life The answer to your question is: It Depends...
- It will vary based upon driver preference, tires & pressure, engine, track vs. autocross vs. daily driver, etc.
What are the Factory Recommended settings?
- Keeping that in mind, here are some numbers I've come across. used #1 last year and didn't have any gardening adventures
1) Camber -0.9 all around. Toe in: Front 1/8" rear 1/16".
2) Camber -1 to 1.5 all round. Toe: 0. track use
3) Camber 1deg 20' +/- 0 deg 15' (Negative). Toe Tracking : 0deg 20' +/- 0deg 10' Toe in
4) -1 1/2 camber FandR , 1/16 toe front and 0 rear.
5) Camber : 1deg 30' +/- 0 deg 15' (Negative)
6) Toe: 1/8 in (total) as a start; if you have huge torque, add a little more rear toe in at first until you get used to the car. Half degree negative camber in the rear, nearly a full degree in the front. Harder driving on stickier tires will tolerate bigger negative camber, but will wear quicker in a straight line and won't stop as well. KitCat: –1.8 all around
