I upgraded to RE71rz for autoxv this year.
I am super impressed with these other than I am wearing the outside edge with almost no wear on the inside.
Tangerine camber boxes are installed camber maxed out and cater naxed or at around 4.75 degrees.

Anyone else experiencing this or more importantly have a solution.

How much camber were you able to get? Not familiar with those tires specifically, but R compound racing type tires often like 3 degrees or more negative camber. If you have less and are driving on track (probably same deal with autocross), they'll tend to wear on the outer edges.

I would say air pressure, but it looks like your roll over is ok at the indicators….

I wondered about pressure as well, but the outer roll over looks correct.

I'll have to check to see what the camber number is.

I'm also going to Sema so hopefully I can talk to someone at Bridgestone.

If i need more camber are there any solutions like a different ball joint?
Or would a-arms need to be modified?

2 degrees isn't too bad. The other possibility is too much toe in - that can cause wear like that at the outer edge.

Is it a dual use car? One of the challenges with a dual use car is figuring out whether uneven wear is from hard use like autocross/track vs. accelerated wear from street use. Especially with soft track tires, and also because autrocross/track alignment setups can increase tire wear for street driving.

A couple other thoughts:
How's your toe set? Toe in can cause increased wear at the outer edges of tires.
To optimize your camber, one option is to take tire temps after autocross runs (or track sessions) and look for even temps.
