Cross-posting from the 944 turbo board...
Going in to have the front alignment redone and check the rear from last year...I cant find the sheet that I had written my last specs down on but here is what I recall:
-2.0 front, max caster, unsure of toe setting
-1.3 rear, probably stock toe-in I would guess
Last time I had a mix-match of early/late parts up front and was using the camber plates in a fixed state....well now its full late offset. Id like to actually use the camber plates and have a street and track setting like my other car has.
For those that have camber plates what are your street / track settings up front?
From reading past threads on the 944 turbo board I couldnt find many people setting up their cars with toe-out up front - any reason for that?
I figure I can get the guy to set a decent street camber setting with a little toe-in and then when I slide the plate in to around -2.0 / -2.5 I can get a bit of toe-out. Im not running r-comps on this car at this time so I think my desired camber numbers are OK for "street" tires (Falken Azenis RT-615's)....thoughts? What has worked for others?
Car has bilstein escorts, no t-bars, delrin in the spring plate, delrin in the front control arm, 968 caster blocks, 968 mo30 sways, 9's all the way around (255 front / 275 rear). Should I leave the rear with stock toe-in? For some reason I recall only being able to get -1.3 camber out of the rear, could be wrong though.
Reason I am asking the above, here are my BMW settings which is my daily driver and feels great, stable under braking/speed with awesome turn-in:
Street: -2.0 camber / toe-in ~1/8
Track: -3.5 camber / toe-out ~1/8
Rear is not adjustable at all on these cars, (just camber d/t rear ride height)
Toyo RA1's 255/40 on all 4
Thanks,
Sam

Front camber -2.6
Front toe out 1/16 total
Switching to slight toe out in front transformed the car's turn-in ability compared to when I had zero toe. YMMV.

Hey;
Only dedicated track cars with solid bushings should run toe out. Too darty, stock bushings are too mushy, and tire wear will suffer noticeably. Run factory toe in (5/64 total) front and rear. Set caster to factory spec, not max. It makes the steering stiff and slow beyond factory. You'll have to fiddle with the camber to get tire wear right, but -2.2 F/-1.8R is a good start. In other words, just enough negative not to rip your tires up. Street tires usually don't respond to camber much anyway. Start conservative and work up if you feel the need.

sam has track tires for this car- Im running 2.5 camber all around and it works excellent w/ my tire setup.
ive always run slight toe out up front and turn in is excellent. Rear has toe in and theoretically on excel when the rear sqats it pulls out straight instead of toeing out.
