Aligning rear toe
I want to align the rear toe, and am wondering if anybody wanted to share his/her experience. I know the right rear toe is out of specs. I can measure the alignment using strings and basic geometry.
The question is about the procedure. I bought the special tool for the alignment. I've seen diagrams of the control arms, but I don't have a full understanding how the adjustment works. I know there is a slot where I plug the special tool to align the toe. Does the toe adjustment change the camber considerably? Right now I have -1 deg rear camber, and want to leave it this way. Do I need any special wrenches? (I have several kinds of "regular" wrenches). Any comments/suggestions would be welcome.

The large bolts are really difficult to get loose with the car on jack stands as it's hard to get good leverage. You might have to put the car on a local lift to loosen the bolts. If so then calculate how much you have to move the wheel fore/aft to get the toe you are looking for while the car is on the lift.

Don't do your own alignments, it isn't accurate enough. Personally, after driving many cars with very different alignment settings, I tend to like -2 or -2.5 degree camber front and rear, 0 toe all around (kills tires fast), and about 6 degrees caster. This is a very agressive set-up though, so I wouldn't use something that extreme if you don't track the car regularily.

Thanks for the advice.
SoCal Driver: do I need any special (extra thin, extra large, etc.) wrenches? gearhead290: I want to make the rear toe within manufacturer's specs. I autoX this car, and anything outside the specs would bump me out of the stock class. One day i might go agressive, but not yet. I do my own alignments :-). I believe I do it accurately enough. I tested it once: I measured the alignment a few weeks after having it done in a shop, and came with almost identical numbers. Alignment is tedious, but it's not rocket science...

OK, I've done it. The procedure is not very difficult, as long as you trust your alignment procedure (I do...). The toe adjustment tool is a must. I changed the right rear toe from +0 deg 20' to -0 deg 1' (the specs are 0 deg +/- 5 '), while preserving the camber within specs. The range of toe adjustment turned out to be about 30'. The left side was fine, so I didn't touch it.
Ironically, I don't feel the difference while driving, but hopefully it will help im autoX.
