[RACER X #99]

Wow, your getting 1,500 street miles on tires that are made for the track. I run the same tires without the hand grooving and get about 500 miles out of a set of rears for track only use.

NFN but it is a mistake to expect any kind of mileage out of these tires.

As far as the inside wear of the left rear it is common with the Jag rear to get lots of camber gain especially when doing hard cornering. Don't forget these tires are real soft and any amount of misalignment (as in hard cornering )is gonna show up in premature wear.
Do yourself a favor and buy a set of street tires and leave the race tires for the track.

If you insist on running these tires you can always go to a much stiffer FRONT sway bar. I did and it helps with the rear camber gain.
