Keep in mind that partial degrees can be given as minutes 16" (16/60) and decimal degrees, 0.28 as above.

The "UK Specs" give toe in both inches and degrees minutes:


The 2000-2003 Shop Manual Spec rear total toe-in is 0.25 inch. This bulletin shows it as 1 degree which is wrong (1 degree = 0.44 inch).
The UK Spec of 0º 40" is equal to 0.29 inch rear total toe-in

Is that with a 255/40/17 or another tire with a 25" diameter?
Yes 25" tire. The exact conversion factor is .4363 (sin(1)*25). So your 1/16" total is .143 decimal degrees total.

The UK spec toe setting of 20 minutes each side seem a bit excessive. Are most of you guys close to this setting? I'm only running 20 minutes total toe-in in the rear. That is about 4mm total toe-in for a 255/40R17 wheel.

25.4mm = 1" in case you're wondering.

I was joking. If you're into car math I have a spreadsheet with a bunch of formulas here: robrobinette.com/misc/automath3.zip

And the MathCad version here: robrobinette.com/misc/automathcard.zip

looks like my thread has gotten out of control

so does everyone with a square set up use either equal neg camber front and rear or a bit more in the back than the front? Reason I am asking is a friend of mine who was an avid racer could have gone pro from England suggests having more up front.
