I can only get -0.5 camber on the left-rear... :(

[HFR_Racer]

I can't get enough neg. camber on the LR of my '87 930. I just got done installing the Elephant Racing OE style rubber bushings and had my car aligned by the local wrench.

I can't get enough negative camber on the left-rear. All other corners are ok.

I've adjusted the camber to ( max. negative ) by aiming the eccentric lobe for he camber adjuster down. This rotates the banana arm clockwise relative to the rear axle center.

NOTE: THE STATEMENT ABOVE WAS MY MISTAKE... THE ECCENTRIC LOBE SHOULD BE POINTED UPWARD TO INCREASE NEGATIVE CAMBER. MY ISSUE IS FIXED NOW SINCE I FIGURED OUT HOW TO ADJUST IT

My ride height is 25" front and 25 1/2" rear to the fender lips with ~1.2 degrees of rake. The car is obviously low so I would think that more negative camber should be easy???

Please enlighten me on what I might be missing. I do understand how the eccentrics are intended to work.

My next option is Camber Max adjusters..

Surprising that your "local" wrench aligned your car and couldn't figure out how to get more - camber ...
There has to be an obvious reason as you should easily be able to get -2 degrees in the rear,i would suggest you take your car to a real Porsche shop who has experience in alignments and i'm sure you will get the results you are looking for !

Just sayin ...

Cheers !

Tighten the pinch bolts, then loosen them just enough to let the camber bolt move the arm.

What were you able to get camber wise before the bushing install?

Could be a bent trailing arm.

[HFR_Racer]

I likely had 2 degrees before since the inside edges of my tires were flat worn out and the outside had full tread. When you refer to the trailing arm I assume that you mean the aluminum (banana) arm and not the spring plate. Correct.

I do not believe that the banana arm is bent. The car has not been wrecked.

I did not replace the bushings on the banana arms (near the center of the torsion bar tube). I only replaced the spring plate bushings since I've read on this board that the banana arm bushings on a 90k mile car usually look good.

Maybe this isn't a true statement?

All advice is wanted..

Thanks for the tip Phil.... I'll certainly consider your advice.

Traiing arms (bananas) can be bent simply from an especially severe impact like a big pothole at 80 mph or curb hopping on a racetrack. The steel ones will bend, but the Aluminum ones as I understand will fail (break/fracture) before being bent very significantly,

I just ordered a set of cambermax adjusters for my car,from the feedback i read, it seems like you can't go wrong with them ...

My car will only be out in April for another alignment and corner balance so i won't be able to comment on them yet !

Cheers !

Bent the crap out of it, got a little to sideways coming out of a turn and just nicked a curb with my rear wheel. Got home, Fuch scraped to hell, 0 camber.

I've figured it out.. I was turning the eccentric lobe downward... I needed to turn the ecentric lobe upward which forces the aluminum housing upward.

My bad..... I was able to get 1.5 degrees easily. With the adjuster turned maximum ( for positive camber ), I was only able to get ~ 0.5 degree ( neg. camber ).

Thanks to all that commented...

I agree that the banana arm might break rather then bent.

I've been told that you only need camber max if your trying to get more than 2.0 ~ 2.5 degrees of negative camber. My 930 is a street car, not a track car mostly. I don't need that much camber.
