I would class myself as an "average" driver (i.e. I am near the top of F2 TC in our club, but are generally beaten by a couple of laps in our F1 class). I have raced the 007, the 009 and now in the last month, the T3 2010 (not the 2011 - sorry !)
I have been really surprised at how much better the T3 is over the 009 (which is similar to the 008 I gather) - much more "planted" and responsive. (I said the same about the 009 vs. the 007 !).
My lap count has risen by 1-2 laps over the 5min race time with the T3, so is quite significant, and I got a PB last week, running 2nd in the F1 class. The car gives one a lot of confidence in that it goes where you want it to go and is very sensitive to steering inputs. I have been able to clip the apexes tighter and get on the throttle sooner. If anything, I am turning too soon now and clipping the barriers on entry because the turn-in is so good.
Big thumbs up from me
