Performance Alignment Advice

[JB36]

I'm about ready to have my car realigned and I'd like some opinions. Besides street, I'm and avid autocrosser and I'm doing my first DE soon.

The car: '87 911 w/ 22F 28R Sanders T-bars, ER Polybronze bushings, Wevo camber king strut bar w/ monoballs, stock sway bars, and turbo tie rods. 7x16 fuchs w/ 205 55 tires and 8X16 225 50 in the rear. About euro ride height and corner balanced. Bilstein HD front and sport rear shocks.

I'm trying to recall my previous alignment specs. I think it's something like
Front
0 Toe -1.25 camber and can't recall caster
Rear
I think 1 degree toe in and -1.8 camber

Should I run with what I have or tweak it a bit? When I autocross, I'm pleased with how the car handles. It doesn't understeer too bad only on slow hair pin type corners. Sometimes I throttle steer ok and sometimes the rear end gets away from me. I want to give the shop specific specs to align to. Any input appreciated.

It looks pretty good to me(except for the rear toe). At speed on a track you will have a lot more over-steer than at the lower speeds you typically see in an auto-X.

different tires will have different camber needs but if what you have now works for what you use it for the most, why change

the rear toe seems like a lot, the rears usually run much closer to 0, more toe at either end makes the car more stable, less toe frees it up

[JB36]

I'm probably not quoting the rear toe correctly. By more toe, do you mean more toe in? something a 1/16 per side maybe?

What type of tires are you running? Same tires street and track?

Do you care about tire wear on the street?

I think you are mistaken about the 1 degree rear toe. That would be massive.

I'm running Bridgestone RE01s. I don't change between autox and street. They great for both scenarios. I don't put that many miles on them so tire wear really isn't an issue. They're probably not the best tire for DE, but I'm a track newb and I probably won't be at their limits anyways.

What's the best way to represent rear toe to the shop....in inches or minutes? From what I've been reading, just a small amount of toe in should be good. Thanks.

That would depend on the alignment rack, are you getting this done at Rick's? If so he can certainly advise you
