CMC, while your workaround might work, I'd prefer to do things properly.
Second set of wheels is a good idea (BTDT with my other car, a supercharged MX-5), but it still won't solve the problem of front tyres being destroyed twice as quickly as they need be, since the whole tread is not being used.
Mine's DSG, and I find it excellent on the track, although sometimes I wish it wouldn't change up automatically at the limiter. Another annoyance is it's tendency to kick down to second when I'm not careful with the throttle while accelerating out in third gear from slow corners (with MTM chip and no LSD, I find it quicker to keep it in third and surf the torque band, rather than induce frantic wheelspin in second).
