Your welcome!

I found that most members experience difficulties finding the specs of these cars and settle for the E46 specs as a result.

These factory specs are from my Hunter Engineering software and thought everyone can benefit from this.

Nothing on the 20"

We will attempt the 19" spec for the 20" within the next two days and I'll notify you with my feedback.

Not sure how these are read.

For the E92 with 18", specifically the front camber reading, does that mean that the acceptable range for "good alignment is from -0.7 degrees to +0.1 degrees?

Thanks!

Exactly! You already knew the answer.

would i just give the alignment place the sheet you guys post and they should be able to do those settings?

Alright, the camber specs will have to be completely off. The car is now on the rack and we will have max out the negative camber so the 245F and 285R can clear.

All the other specs from the 19" spec will suffice for the 20" wheels.

You may be out of luck with a 25 series rear tire. A lot of pressure is forced on the inner tire section with the already negative camber.

As you suggested, give them the sheet and let them find out if it's in range. Who knows, it may be off. I hope so.

The sheet they print out will be true. Any adjustment to the sheet will only be the result of any alteration on the vehicle.

What size are your rear tires? If the tires are wider than 255, you may have to compensate the camber to the possitive end of the range (if fender clearance permits).

good stuff Ray!

Everyone - I had Ray's shop do the alignment a few months ago and so far so good. They adjusted everything to be within range and i haven't had any problems so far. Steering straight and tire wear is normal so far.

BTW I'm running 19x8.5 w/ 235/35 and 19x9.5 w/ 275/30

Glad to hear! Let me know if you suspect anything unusual.

Any place that updates their software will have this info. Unfortunatly, not everyone does.

deff not every shop does......the reason i am iffy about my shop is because i watched the tech align my car.....he set the toe all around to .05 then he print out the sheet and went under the front end of the car and tightened one thing on each side of the front of the car....this gave me the feeling like when he tighten it up maybe it threw it all off?

Im going to get aligned at another shop tommrow to make sure its all good...its worth the extra 100 bux
