I have a 06 z06 and I put more spacers on the top part of the arms..There were like 3 already.I think I need more. Tires are wearing on the inside a lot more then outside..Is there an adjustment for the lower arms?? Or just load up upper arms to make wear better?

The stock alignment for the Z06 is pretty aggressive (more for track). Take it to a good alignment shop and tell them you want a less aggressive alignment and tell them the insides are wearing much faster than the outer. I believe it's the toe-in that needs to be adjusted.

There are eccentric bolts on the lower control arms to adjust camber.

Excessive toe will chew tires up quickly, much much faster than camber will.

This. All day long.

Yes lower rear arms are adjustable. Take it in for an alignment, which is something all owners should do. It makes a huge difference.

Did you adjust the toe after installing spacers behind the upper control arms? As soon as you installed those spacers that pushed the upper part of the knuckle outward. Since the knuckle is tied to the steering rack by the tie rod with the attachment point in front of the knuckle you increased toe in. If you had adjusted the lower control arm cams toward less camber you would have moved the lower part of the knuckle inward which would have increased toe out.

ty all. I will look again for a lower adjustment point too bring it in a bit as I changes my tires.I did look for a lower spot and didn't seen anything that I thought might bring it in..Can I put more spacers on the top? There are 3 already..I do like the tire sticking out of the well more then inside the well that's why I have 345 wide tires. They should pay you guys for your help to so many..

I take it you are talking about the rear tires as you mention 345s. The lower control arm camber adjustment cam is located at the point where the front of the LCA attaches to the cradle. If you don't see a cam with a bolt through it at that location then it is possible somebody previously installed some fixed camber plates in place of the cam. As for the number of spacers at the top do you have bolts holding the UCAs in place or do you have studs with nuts?
