Problems with Front Camber

[Fishcop]

After recently upgrading all my suspension bushing with weltmeister, I took the car in today for a 4 wheel alignment.

I gave them my prefered settings (Rear -1.8 and Front -1.0), however they could not do any better than L -2.28 R -1.76 What would be causing the lack of adjustment?

A camber brace has been a suggested addition to help push on the towers? Good idea?

Input welcome

You shouldn't have to be 'pushing' anything. Sounds like something is bent.

[Fishcop]

Hmmm, that's what I was afraid of. The rear adjusted perfectly, but they complained of "a lack of adjustability" on the front.

Is your car lowered? That can cause this problem.

You can do some grinding to the hole at the top of the shock tower to pick up a little more range.

[Fishcop]

Okay, that would explain quite a bit!

I lowered the car by about 1" when I did the front A arms. So a combination of lifting the front a little and reaming the hole will probably fix it?

Thanks Chuck, your advice is invaluable

John,

Ream here:



I took out about 3/16 inch and gained and extra degree of range.

Your rear sounds like it's fine. But you can gain range by grinding the spring plate too. Or you can fit a smaller bolt to give more range.



Good luck.

I've seen this before. It was caused by a cracked weld where the strut tube inserts into the spindle. They just tack weld those parts and a good pot hole or curb hit will bust that weld. Might want to check that out prior to grinding. It's the kind of thing that you might not notice unless you look for it.

John,

Go to this thread and read the second scanned picture I posted. Towards the bottom in Tech. Tip One, it says that some 911's are hard to get neg. camber, blah blah blah. I'm not saying this Weltmeister info. is gospel, just saying that it's not necessarily something wrong with your car.

A lot of 911 guys would love to get that much camber for the track. Kumho's want 2-3 degrees of negative camber for example.

Had the same problem. Bought a set of ERP monoball top shock mounts, and that afforded some more (i.e. less negative camber) adjustment range, plus I also reamed away a little of the metal as was suggested above.

Thanks! Great stuff from everybody.

One day I'll have a weekend where all I do is drive my car

Now where is that die-grinder.......
