Rear camber adjustment - how?

[Kaz117]

Hi all,

My Z3 has coilovers and I like the look of it being lowered around 1.5-2 inches, but the rear camber is around -2.5 degrees due to the trailing arm geometry.
Is there a way to correct this camber without lifting the ride height too much? I've had a look but it looks as if the rear wheel hubs are hard bolted to the actual suspension arms.

There are other bushes that raise the rear subframe a little to help.

Then there are two options for adjusting the trailing arms if you want more. Concentric bushings that are adjusted by turning the bolts. I hear these can move but I have no experience with these so it's only second hand feedback. The other is weld in kits so you can adjust the position of the bolts positioning the training arms.

My car has a combination of the raised subframe and weld in kit. I can adjust the rear suspension as wanted.
