what causes the rear tires to wear on the inside more. does that have to do with the rear toe steer or w/e or do i need a camber kit. jw, cuz in a cppl months ill be gettng new tires and i dont want those to wear like these.

Mazdatrix sell a camber adjustment rod for the rear, you need to buy one. I think they are about 100 bucks. From the factory the rx7 has no adjustment for camber in the rear, and you wont get it done in the front for 50 dollars either. I had to pay 195 dollars and they still couldnt get it right. I take my car back every week or so and they do it again for free.

do they sell the kits for the front also? i dotn think they are wearing like that, but itd be nice to have the adjustment

Your front already has camber adjustment but it is pretty coarse, if you would like some finer adjustment I would buy some pillowball mounts that are compatable with stock strut assemblies, I know Cusco makes some as well as Tein, although I dont know it they are compatable with stock stuff.

might be dtss that does that?
