I installed them myself (very easy) and then had a good alignment shop set the suspension up to specs.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Does anyone here have any experience with fitting adjustable rear control arms (top) on their 996s to solve the too negative rear camber problem and resulting inner rear tire wear on lowered C2s? I just put on a new set of 285/30/18s (on my stock 10Jx18 rear wheels) on my 2003 C2 (with M030 and H&R springs that lower it by 30mm) after finding extreme inner tire wear. My alignment guy could not get the camber into factory spec (too negative), but said that if I got a set of adjustable rear control arms (top) he could get it into spec and the uneven wear pattern would be reduced or eliminated. I know this effect is common on lowered 996s and with the price of tires I would like to solve this problem. I am not tracking this car. I found sets of these adjustable rear control arms (top) for ca. $350-550 and wondered if there is any collective knowledge on this forum of how well they work. Any problems with tire rubbing? (I tried a search, but did not find anything really relevant.) Thanks.

In the same boat as you were a year ago...did you ever figure it out?

POST 3 / ORIGINAL POSTEROriginal post

Hi, Yes, I solved the problem completely by installing a set of (4) adjustable upper rear control arms. Following this, it was easily possible to get the alignment into specs. For the record, I bought the less expensive set of adjustable control arms that I found on EBay and they work just fine. I think I paid around $400 for the set. I installed them myself (very easy) and then had a good alignment shop set the suspension up to specs. No more excessive inner tread wear. I have tracked the car and it handles beautifully. I would advise anyone who has experienced this problem on a 996 to take this approach to solving the tire wear problem. Over the life of the car, this "fix" easily will pay for itself in reduced premature tire replacements. Good luck!
