looking for some alignment help for my track car. 08 CR

Current set up:

Stock CR suspension with the following:

17 x 8.5 +59 squared wheels
245/40/17 star specs
spoon x brace
S2 J's balls up front can adjust up to -4 to -5


Current alignment:

front -2.5 0 toe
rear -1.8 .28 total toe in


it has been pretty nuetral so far, but the rear gets a bit loose still in the corners, does anyone think I should run a bit more negative camber in the rear? say even it out to -2.5 front and back or even -3.0 front and rear? The car is stable at high speeds so I think the total toe in is o.k.

Appreciate the input, I run at mostly Road Atlanta, Roebling Road, and Sebring

thanks for any help you can provide

 

Given that we both run CR suspension, CR aero, and 8.5" wheels, here's my alignment. Take it for what it's worth.

J's S2 and SPC camber joints are used. 255/40/17 RS3, so the toe measurement may be ever so slightly different.

Front
-3.5 camber
0 toe
~6.5 caster

Rear
-3.6 camber
5/32" total toe-in


Can someone convert the two toe measurements to be comparable please? I don't know the conversion formula..

 

I would def. look into more camber in the back. I dont have a CR, but it run -2.5 all around, i cant remember the toe settings though

 

thanks for the information.

 

5/32" total toe = 5 divided by 32 = 0.156 inch

My AP1 likes 0.2 to 0.25 inch total toe-in. I've tried less toe-in twice and both times the rear end got "quirky."

 

I thought tire diameter was somehow factored into the equation?

 

You're thinking of the conversion from inches to degrees which uses sine waves and unicorn rays. I try not to mess with toe in degrees.

 

1 degree is about .44 inches. So .28 degrees is about an 1/8"

Haha thats what I was thinking of! Unfortunately my alignment shop uses degrees so Im trying to figure out this witchcraft in order to get the equivalent of 1/16" total toe in in the rear. Running 255 R-S3s all around if anyone knows how to help me

 

Is that with a 255/40/17 or another tire with a 25" diameter?
