Just a quick comment about the uneven front tyre wear, I had exactly the same on my S2 with the original Bridgestone RE040s, strange it happened with all of the sets of RE040s I fitted, other people have also had the same. I started using T1-Rs about 18 months ago, mainly because I found the RE040 to be poor for the last 3mm or so of tread, and I never liked them in the wet. Once I fitted the T1-Rs I stopped getting the uneven tyre wear, I have had the Geo checked once, this was with the second or third set of T1-Rs and I had the front camber adjusted more negative, so the inside tyre wear should have been worse. So in summary the front T1-Rs don't seem to wear on the inside like the RE040s did, even with more negative front camber, I can't explain it, but this is what happened.
