I'm in sprightly na (then with extra weight added with an sc). I'm running 24fr 26 rear at the mo (AD08R's) but havent done a lot of tweaking yet, need to run it on track to get a better idea as the weather hasnt exactly lent itself to spirited driving lately. Am a bit concerned that as these are wider than the TD's may also be worse on the aquaplaning front.
Stopped my wheels from rubbing, simply by removing the centre bolt that holds the arch liner in place (thanks for the tip chaps). There are two others that seem to do the job fine on there own.
