It seems there are 2 main issues on the rear of these kitsDragging up an old post... @foggy3061 did you ever get resolved?
I think i may have the same issue with a T6 I have just purchased and would love to know how to resolve it. Thanks!
1,. was a poorly made shock absorber , Dont buy any more of them change it to a known better part , we can help with that !!
2 The height adjuster is poorly engineered and makes noises when the rear suspension articulates over bumps , we have a primitive but effective solution to this also .
