I did a lot of auto-x runs the last week (30+?) and I've worn my new dunlop direzza star specs a lot on the outside edge

Would running more negative camber help the tires wear more evenly?
I'm at 0.6 in the front and about 2.0 at the rear

I was thinking more 1.2 and 2.5 at the rear?

I am getting some RA1's soon so I want the car to work on these and for trackdays as well as auto-x

Yes, increasing your camber should help. In the front, you should probably max caster first, then get as much camber as you can. Hopefully you can get enough camber out of the stock suspension.

In the mean time, get your tires flipped.

You can get close to the stock caster spec with the front camber set to maximum. I would try for maximum camber first, then caster. 1.2/2.5 is pretty extreme in terms of front/rear difference. I personally wouldn't go any higher than -2.5 for the rear wheels.

Maximum is probably somewhere between -1.2 and -2.0 on the front wheels.

The RA-1s will require more negative camber than street tires to prevent excessive wear on the outside edge.

I run -1.8 in the front and -2.25 in the rear and experience zero outside shoulder wear on both street and R tires.

consider air pressure as well. I have had good wear at 36/32 psi and -2.0/-2.5 F/R.
