alignment setting for road racing [3]

a recent "off track excursion" at thunderhill has left me in need of an alignment. just curious what others are running, especially in camber front and rear.

running a fd with 245/17 front and 265 rear. GAB shocks/M2 coilover/RB swaybars. corner weighed. near stock ride height.

I have always used the Pettit recommendations on their site. They have settings for various wheel sizes and types of driving.

Fabian,

I've some alignment suggestions on my website:
http://www.purplemantis.com/RX-7/gab_super_r.htm. I recommend keeping toe at zero, particularly if you drive you car on the street.

I use M2's suggestions with 18s to good effect.

I'd ask what's your driving style? If you're comfortable with the rear stepping out a bit, then I would recommend being more aggressive with the alignment. If you tend to over-react when the car oversteers, then I'd say be a little more conservative.

Pettit's website is a little conservative, if you ask me. They recommend 1/16" toe out (F) for autocross ... if you're really competitive, you'd want something more aggressive; like 1/8" toe out (F). If I had your setup and my FD was strictly a track car, this is what I would run:

Toe: 1/8" out (F), 1/32" in (R)
Camber: -2.2 (F), -2.0 (R)
Caster: +5.5 - 6.0

If your FD is street driven, you might want to back off the toe out.
