rear camber fix for lowered suspensions

[rocksnap]

I installed a coilover suspension a short time ago and had it aligned afterwards. I also installed the Direzza Sport Z1
Star Spec tires. After about 1000 miles the inside edge was getting scalloped, creating a dreaded thumping. Some of that can be atributed to them being really soft but the point being the camber is within factory specs. When you lower a car all bets are off for stock settings.

I looked hi and low for some kind of camber adjustment device for the rear. I even bought the red pin wheel kit that is supposed to be bolted between the stub axle and solid axle but after receiving it I brought it back after seeing what it looks like.

What I am finally doing to correct this is buying, then machining new rear stub axles, $135 delivered online. The axle has a thick steel plate that can afford to loose a sliver of material to bring it into proper alignment. I am having to shave it for a 1 degree camber change on my car.

You could have your car put on a alignment rack to see exactly how much camber and/or toe you have now to machine the new axle to within specs. Afterwards you can just bolt on the new shaved axle and be on your way. There should be no reason to put the car back on the rack except for piece of mind... I am saving my origional axles in case I ever go back to the stock setup.

I have an Endura Tec coilover kit which has no more than a 1.5" drop. The stock tires were still wearing OK. When I put on the Dunlaps they had the problem of wearing the rears on the inside. Again, they are a very soft tire and may not take being "still in factory alignment specs" but really out of specs with it lowered. The factory specs are a ball park at best when a car is lowered. A competent alignment specialist SHOULD adjust it to where it needs to be. Which may be different than what the stock specifications are.

But the point of my post was to help some people out who did lower a bunch and were having camber and/or toe issues as I am. With no available adjustments to be had with the stock set up I had to think outside the box. Not only will I get better/proper tire wear I will also have a better handling car. For the many miles I plan to have this car.
