Phil,
(1) Thanks, excellent feedback.
I can relate 100% to the rear end issue when exiting a corner.
(2) I'm getting things a lot better than the kit setup but have not had much club track time since I purchased my TC (will make up for this when the new club opens around the corner from my place).
(3) Yes, my diff has been loose, so your diff comment is very relevant (and might explain a lot). I check my rear diff tension by holding both the rear wheels and trying to turn the centre pulley with my thumb. Just to confirm, this needs NO slip whatsoever. Also, I have just installed ceramic diff balls (not had the chance to run yet).
(4) Some photos would be greatly appreciated
I should be able to mount the belt tensioner somewhere else (if needed).
(5) I have two TC cars, so I can try cutting stuff, and still have an original as well.
(6) If you could post your setup that would be great
I analyse them so I get a better understanding of what works under certain conditions (eg: lo, med, hi, & carpet tracks)
Thanks again
