why is passenger side rear tire wearing much faster than driver's

i noticed that the passenger side rear tire is wearing out a lot faster than the driver's side rear. inner/middle more than the outer. why is this..?

Just happens to be the side the diff is favoring. That is a big part of why these cars can use a nice LSD (Quaife).

Ya Pro, like Jangy says, right rear is the primary driven wheel. A Limited slip differential will help gain more traction by driving both rear wheels in a condition of uneven traction.

The inner tire wear is caused by the squat in the rear of the car under acceleration. As the car accelerates the weight transfers to the rear compressing the suspension and causing the rear camber to go positive (top of tire goes inward and bottom of tire goes outward this yields a high pressure contact patch on the tread at the inside half of the rear tire.

you're right with the cause, but i thought negative camber has the top of tire more towards the center, not positive like:

I have the 030 with the LSD, and the tire wear was slightly more on the left rear than right, but not by much.

You are 100% correct

/-\ negative camber
\-/ positive camber
