BMW 330 ZHP alignment and data + Pics

Here's the results of mine:

Not bad.

I had some work done on my car, so I wanted to center the steering wheel and get an alignment. I decided to try the local mechanic to see if they could do it. They said that they could possibly bust the control arms if they tried to adjust the rear, so I told them to leave it as is. I'm guessing this is a common problem with old control arms?

So after I drove around for a while, the car has a tendency to steer right. Any input on the below print out?

I'm thinking the right rear toe is the main problem. Would the difference in camber from left to right also factor in?

Your rear toe could definitely be causing your tendency to steer right. That is about the max toe in I would personally want as a total, but seems to be excessive for one side. It will cause more wear and definitely uneven wear between rear tires. It's like your car is steer slightly right with the rear wheels. I would think a shop would be able to align right or let you know they can't do it.
Try asking them if they will straighten out the rear toe to an overall toe of +2.0~(making sure it is equal to on each side).

The camber difference in the rear should not cause much problems. It is not ideal, but will not effect pull to one side or the other. I've never heard of busting the control arms while adjusting camber, as long as within the factory camber ranges there shouldn't be a problem. Consider adjustable control arms for the future and camber plates for front if those adjustments are important enough to you.

I would have them fix the toe. And when they will adjust that, the rear camber will change as well

Maybe they could not break loose the eccentric bolts in the rear since they were seized ?

I'll probably go to a different shop, have them check the alignment and if the front still looks okay, just do the rear.

Mine from last week.

They adjusted it wrong and would not redo it for free, but it is pretty fun. I think a little + toe in the back would help it stay planted better, but It's fine for around town. I break lose pretty easily and had fun this week in the rain.

2 months after installing Koni yellows I checked under the car and discovered dry rotted right rear tire so replaced all 4 Pirelli's (from PO) with New PSS's. Wow what a difference! Mounted, balanced and Hunter 4 wheel alignment done at a reputable BMW/Porsche racing oriented shop. Can't help but wonder though if this level of camber (-1.0 front, -1.9 rear) will result in drastically reduced tread life on staggered wheels/street life only....appreciate any thoughts from those that have been there and done that! :cheers

Camber will not drastically make the tires wear out faster. Bad toe will do that however.

The current measurements on your zhp are right in the factory specs. No wonder you noticed a nice difference in the way the car drives because your alignment before was off especially in the rear.
