Yep, I have run this setup periodically since 2009 as have most Texas SPBOX drivers. What do you want to know?

My impressions:
More ultimate cornering grip.
Tires can be moved around to all 4 corners to maximize life.
Brake bias moves forward so the car tends to duck more in braking zones. Front brakes overheat more easily and wear out faster.
A bit slower on long straights. (more un-sprung weight/rotational mass and windage)
Is it faster? Maybe in AX, not in my car on the track.
