Rear camber adjustment?

[magpies]

Looks like my nearside rear trailing arm is bent 🙁 found the reason the inside of the tyre is being scrubbed off 2.5 deg camber and 39min toe out. As it has later trailing arms, the toe can be adjusted by shims in the joint. BUT I cannot see how the camber could be adjusted?? wedge shim the bearing housing??

I shim between the bearing housing and the trailing arm to adjust toe/camber on mine. In my case I'm increasing negative camber so the shims are at the bottom, which means there's no reduction in the engagement at the top where it's taking weight and damper loads. Going the other way, you'd need to ensure you didn't compromise that connection.

The trailing arms are pretty stout and I'd be concerned whether whatever bent it has done any other damage. I've had a trailing arm let go at speed - one star review, will not be repeating.

Cheers for that. I'd probably look for closer to -1 deg camber rather than the -2.5 that I have.

Staying with the rear do you run a little toe in or parallel?

It's subjective and depends how you want it to behave, but what works for me is zero toe for a nominal -1 deg camber, add about 0.1 deg toe-in for each -1 deg camber. I typically run somewhere between -2 and -2.5 camber. A tiny amount of toe-in with that reduces scrub a little.

Is the -2 to 2.5 for track?

My driving is mostly 'spirited' road and some track. I thought initially -1.5deg for all 4 wheels along with close to 0 toe.

That seems perfectly reasonable.
