My alignment guy told me that the e9x rear geometry can slip under high cornering loads etc. It seems plausible because it's only held by the friction preventing those eccentric bolts from spinning, but I haven't found any reference to it online...anyone had it happen to them? Any permanent fix for it? I've seen fixed shim kits for the M3, but they don't fit the non-M arms, as far as I could tell.

I assume you mean these? https://www.e90post.com/forums/showt...t=camber+shims

Yeah, those are the shims. Right enough, it says right there that they work on non-M arms! A lot of £$ for a handful of laser cut pieces still! Maybe I'll make my own...

Anyone experienced the slippage for themselves?

Doubt that 99% of the owner group ever runs into this...you'd have to have some seriously sticky tires and severe duty track use to be running into this issue IMO.

Agreed though...if you have the means to, just make a set of fixed shims in the most neutral position and upgrade the arms to provide adjustability:

Will make setting the alignment much less painless and will save you a bunch of money at the end of the day as well.

My thoughts exactly. I'm taking it for a check next week, at the same shop who set it earlier this year. I feel like it's slipped, but I have no evidence other than my posterior.

This adjustable arms are interesting. Shame I'm in the UK!

You can always mark them with a pen, or etch a mark.

Of course, but I didn't at the time... :/

I'll try and remember to do it next time
