I am looking at it for double duty - track and street. It will be my daily driver, as a matter of fact, but as I commute 1 mile to work (when I don't ride my bike), that shouldn't be an issue.

I guess there are two questions here. What are the unique dangers associated with driving the gt3 on the street (eg unsettles on bumpy corners, causing the car/rear to skip, has a tendency to hydroplane using stock tires, etc), and what are the "tricky" behaviors it exhibits at the track when approaching the limit? (eg avoid trail-braking, trailing throttle, need to load up the suspension before turning in, need to get on the gas early (pre-apex), etc???).

If it is easier, what are tips unique to driving the GT3 smoothly and quickly?
