Here's a pic of a bent control arm also shows the adjusting bolt.

Thanks all, this has been very helpful. I will get the car up on jacks and take a look to see if anything is bent.

Should I fix this issue, what would be the ideal toe and camber settings for maximum tire wear for a stock suspension z4 m roadster? It's not being tracked, I just drive it on weekends... Just a cruiser with top down on sunny days. Just looking for max tire life. Thx.

Use the miminal camber settings and minimal toe settings (OEM) from the link I left on page 1.

^WHS

I run minimal camber (-1.1) and zero toe on my rears on track and it's fine.

The data from the link is not correct.
OEM TIS specs are as follows (e85 M roadster rear axle)

Total toe: 0° 22' ± 6'

Camber: - 1° 50' ± 15'
(difference between left/right max. 30')

The displayed value in the OP of Camber: -2.1 is the TIS value for the non M roadster.

Yes. Please fix. You pay for it with tires or upfront. Your choose.
