Lowering kit wore out my tires!

[CatAlpha]

My son bought a used 99 Eclipse GS with about 60K on it. Already had the lowering kit installed when he got it. It also had new tires, and brakes. He put about 6K on it and the inner edge of both rear tires wore down to the threads. (One went flat). I'm still getting the info on what kit manufacturer is on the car, but my question is, is there an adjustment or alignment procedure that will allow for normal tire wear/contact pattern with such a drastic lowering kit?
Thanks.

a real common lowering issue. you'll defently need an alignment and camber check.

here is a quick read from the parent eclipse/talon/laser fourm. give it a look. it will help explain whats going on.

that's wayy too much reading for me. basically when you lower the car, everything moves closer to the ground except the center of the rim, that stays the same distance from the ground as it was before. therefor to have the hub attached correctly to the rim, it needs to lower the center of the rim by tilting in inward. that's why your tires wear out so fast.

ingalls sells good camber kits. you'll need to get ones for the front and ones for the back.

With a big drop you too much rear camber, and some toe.

The quick answer is what scottsee said. Here's a list of what to do:

1) Go get an alignment, figure out your camber. It should be off
2) Go buy a camber kit, or Home Deopt one together yourself (it's basically washers and bolts between the upper control arm) to correct for the camber you have via the stock spec, found on the page scottsee linked. For example, if your camber is negative 2.5, and you want 1.5, add enough washers to correct for the difference, 1.0 degree of camber
3) Go get an alignment to check and see that you did a good job guessing how many washers you needed. Again, see the link. Toe has to be adjusted last in an alignment job, after camber. Once you know the camber is right, have them adjust the toe to near zero. That's their job, not yours

It's not hard, or expensive. Certainly not with the back of the car, at least What gets expensive is killing tires with a quickness.
