go to a proper alignment shop that deals with race cars, including drift cars, and see if they spot anything beyond the glaring issues of your camber and insane toe specs

you also didn't give us your tire compound, which is also a factor

tire wear is always gonna come down to:
- camber
- toe
- compound
- driver

everything you gave us is that your camber is high, your toe is NUTS, and your driving is hard.

wtf u expect us to say? we aren't looking under your car, we aren't gonna point out a magical gremlin thats eating your tires at night

Actually toe is the greatest influence on wear I forget the actual equation or saying but it’s always x amount of toe is worth more than x amount of camber but yes all his angles are completely screwed. You essentially put so much -camber that now the outside of the tire isn’t really even touching and then added so much toe your dragging the tire across the pavement the whole way scuffing the **** outa the tire. Sorry op but really any alignment shop shoulda been able to tell you this was a bad plan.

The tire tread block edges should really be feathered out.

I'm guessing the gremlin is adjusting his camber at night.

See, this is the kind of input i was looking for. The shop i went at was sure the toe was in spec and helped compensate for the camber, therefor i did not question it as much as i should of had.

I have an appointment at another shop which was suggested to me by a few guys who drift near me. over the phone he sounded confident he could ligne it up with my camber setting, plus he has a z a well.

so to be continued i guess

Camber will stay high. You're saying my toe is off, that small bit of info was all i was really looking for.

Your spec's should be around -2 to -3 camber, caster +7, toe zero to 1/16" in for the front. The rear, camber from -1.75 to -2, toe zero to 1/16" in. The rear camber curve in the rear is not linear. As the rear squats, the camber goes more negative quicker.

You can’t set toe to compensate for camber. I get what he may have been trying to do but it just doesn’t work that way. Toe in will wear the outside edges of the tire faster as your essentially dragging the tire across the pavement rather than rolling. So in his theory your neg camber with pos toe would cancel each other out but it just doesn’t work like that because as stated earlier your camber is just making the inside of the tire contact and now with your toe your dragging the tire across the pavement on that very little contact area.

Get the toe set right and that’s the best you can do. Your still gonna have excessive inside wear from camber but it shouldn’t t be as fast.
