Hi All,

My rear suspension carrier is slightly bent, has been for over 15 years and has always been wheel aligned OK.
Recently replaced all the rubber bushes with poly black race series bushes and now we can't dial out all of the tow out in the rear (I am crying).
The guy who does my alignments is very good as has been helping me with this car for years. He has asked if shims are available for 924's to help give more rear adjustment?

A google hasn't revealed anything, anyone heard of this??

Thanks

Have a look at this video, maybe share it with your friend, a refresh on how the suspension geometry settings work is worth it.

Rubber bushings has it pro's, one of them being compliant of smaller misalignment. Its a reason why they are used stock, less requirements on precision pickup locations.

Depending of the cars usage, if its not a dedicated track car, go back to rubber. New rubber is pretty good. However, it might not be possible to align straight anyway.

I would get a new unbent carrier or remove it and unbend it. I guess the first would be simpler.
