Why the excessive wear?

I like to brake a little early (with some trailbraking, lift to rotate and then on the gas after a split second of delay for the rotation) and go through the turn throttle on way before the apex because it's been drilled into my head and it's all about exit speed (single drive Rotax kart racing where you need to be going through a turn at a high enough speed that you don't drop RPMs out of the power band, but don't go too fast as to spin out).
Sorry for the
but I just had to respond to that.

That would depend on the camber. With no camber, it'd just wear the tire evenly, more quickly, with positive camber, the outside, negative, the inside. The toe-in forces the left wheel to turn in a little to the right and the right one a little to the left so both are a little off from straight ahead. When rolling along, the tire is scrubbing against the road rather than just rolling over it. You want a little toe-in in the rear for feel and handling but too much will wear the tires quickly.
I think it it more a likely camber issue, toe if all things are equal should wear evenly across the entire tire. My two cents. Also toe in the rear is generally not equal between the two tires if it goes out. It is set even but if you get slip from the OE toe links for example one side may be further out than the other. I have some inside shoulder wear also but I am thinking I have more camber then needed. I also run less camber on the right side then the left as well as different air pressure on left then right.

This could be both setup and how you drive the car.
Same problem with all types of tires, makes me think it is perhaps drive technique. (If your setup is not completly scr*wed?).
A good instructor should both be able to feel if something is wrong with your setup and also see if your driving input needs to be altered. I'm sure there are more than one here on RL who can help you.
For fine tuning and sorting things out yourself. A pyrometer and one of those small handy data acquisition boxes are powerful tools. If you're not used to problematic approaches with Data, get a helping hand here too. It's easy to pull wrong conclusions or mask errors with wrong "counter measures".
Hope it works out.
