camber help needed

Any suggestions as to how to measure and adjust camber on a 84 911? Seems to be too negative a setting because all 4 wheels are wearing alot on the inside 1 inch of tread, with no wear at all on the center and outside. I know where the adjustment is for the back. Any hints or suggestions greatly appreciated. I want to do this myself

I have a camber/caster gauge that mounts to the wheel opening. the aadjustment is at the strut tower plate w/3 allen head bolts 8MM socket is needed. You want to pry them to the outside of the car to decrease negative camber. Usually you will only be able to get 1/2 degree negative at their farthest adjustment. hope this helps. 81SC

So, I have to find a gauge that's not magnetic and have someone hold it or find one that fits somehow and go from there, thanks

I know my method is not perfect but it works for now.

I have a piece of angle iron. Cut to measure the lips of the rims (not the tires) then I place a digital level on it. The digital level will measure in either Degrees or %.

This is how I know I have - .5 degree front camber and - 1.5 degree rear camber.

Have FUN!

I hate to sound too crude on this but I had a slight camber problem on my front which I corrected... very... manually.

I had visible camber differences and visible caster differences. It looked like the PO took it to NTB for a 2 minute alignment drill. It had a slight pull to the left and just very "odd" handling. Using a tape measure from hub center to front and back I got both casters exact. Then I fashioned a "plumb-bob" to hang from the top and bottom of the rotor to a handmade measuring scale on the garage floor. Using the left as a basis since it wore evenly, I adjusted the camber of the right to match. After several ups and downs from the suspension, redos of alignment, and trial runs, it feels great, doesn't pull, and wears evenly finally.

Of course, I went into the endeavor fully expecting to have a shop correct my misalignment, but have been happy so far. Just one more thing I don't have to take my car to a shop for. My wife thinks I'm nuts though.

What should I adjust the front and back to in order to get EVEN tire wear? I like the digital level idea.

Caster, camber and toe-in are inter-related alignment angles. Changing the camber may change at least one of the other angles depending on what end of the car you're messing with.

If you're not set up to measure all three, consider using the services of a professional alignment shop. You might get close, but others who have had their cars professional aligned will attest to the difference it can make in the handling of their car.

I agree with Sherwood. However, check out

for more info.

This is how I have been doing my front toe settings for sometime now.

I haven't had the thought to attempt the rears yet.

I will leave this up to a competent alignment shop.

Mike Piera's article is right on. However, most of the DIY procedures I've seen don't include the hot to's of checking/adjusting caster (including Mike's). Ideally, you need a camber gauge and some turntables under the front wheels. These aren't in everyone's tool box, and uneven L-R caster angles can affect the straight line tracking of a vehicle. Moreover, the configuration of the top strut mount adjustment mechanism precludes independently changing caster/camber without somehow affecting the other angle.
