Default Help with alignment specs ..>>

Help me understand these alignment specs. My car is a '01 TT quattro with the standard suspension.

I just had it aligned after changing back to my summer tires and noticing it pulling lightly to the right. I compared the "after" specs I got from the shop that did the alignment with what's in the Bentley, but the Bentley is in minutes I think (front toe= 4' +3.5') while my shop's printout is in decimal degrees (0.05ยบ). I'm befuddled, even after finding Steve's link for the degrees-to-decimal alignment conversions.

Anyway the "after" specs I got from the shop that did my alignment read:

Front
. Camber (L) -0.7ยบ (R) -1.0ยบ
. Toe (L) 0.05ยบ (R) 0.05ยบ (Total Toe= 0.10ยบ)

Rear
. Camber (L) -1.9ยบ (R) -2.1ยบ
. Toe (L) 0.20ยบ (R) 0.15ยบ

The shop said rear camber wasn't adjustable and thought the car still pulled a bit to the right after the alignment so they wanted to swap my front tires left-to-right. As my Michelin PE2s are asymmetric but not directional, I said Ok. Now it's pretty neutral, fading ever so slightly to the left, but it doesn't feel quite as nimble on it's feet as I remember from last fall (when I took the summer tires off).

<b>Are these new alignment specs Ok?</b> The rear camber seems higher than what joe@vwvortex seems to recommend, but he may have a lowered suspension. I've searched previous posts but get lost as many have modified suspensions (mine is OEM springs and struts).

Thanx, ~john

Default rear camber is still high, somewhere around -1.5 would be better

There is no camber adjustment on the car, they are right about that. You'd need the same as a lowered car to get back into spec, kmacs or adjustable arms.

Too much rear toe, as well. Should go for 0 in the rear.

Default 1/16" in is safer -- when the rear compresses (in a turn), neg camber increases, as does toe out

could cause snap oversteer. thus why some toe in is the recommendation. that said, looks like he's got waaaay too much toe in.

Default So 1/16" in would be = 0.06ยบ (to use degrees)?

rather than the (L) 0.20ยบ and (R) 0.15ยบ if I understand correctly. Sounds like it's time for a trip back to the shop.

BTW, what would the effect of too much toe in... Increased tire wear and less nimble handling?

Yes - .06 = 1/16th and yes - increase tire wear and a bit more understeer

Thanks. I've got the Neuspeed rear bar to reduce understeer--don't want to dial extra in (!)
