As of the last few months, I've been ever increasingly enamored with breaking rear traction in the Exige. Ive been experimenting with different inputs, and taking mental notes of events that, in practice, are way different than I what expected, in theory.

All of the following situations are on clean, wet roads, with wear bar rears, NA Exige. no LSD. TC off(and performed on a closed course). unless otherwise noted.

This is what I call a controlled slide, in that what happens, in practice, is what I expected to happen, in theory:
Approaching a turn, in gear, turn in, and apply throttle. The rear breaks loose. Counter steer. Spinning rears. Minuscule amount of lift(<1mm. Adding throttle, or maintaining throttle, I found, just spin the tires), and immediate(the lift and reapply is one motion of up-down asap) reapply of throttle brings everything back in order quickly.
I found that sometimes during mid slide, lifting(TINY amount of lift. 1mm max) stopped the increase of slide angle(spinning rears), and reapplication of throttle straightened it out smoothly. It depends on the amount of throttle used during initial breaking of traction. The lift helps tires grab. Now I'm not sure, since I didn't try, but I think if I didn't lift in the instances where I did, I would have spun right around.

Besides slight throttle input variations(noted in parenthesis above), this is a constant, controlled, repeatable event. This is what I usually try, and successfully, attempt.

Unexpected events:

1. Mid turn, rear breaks loose, total lift. Counter steer. Throttle. Car straightens out. No additional slide angle.
2.As noted in the "controlled" paragraph, following proper theory(apply more throttle) didn't work in some instances.

Before, I always thought that in a slide, one must not lift. But after these events, I can only come to a conclusion that a throttle induced slide requires different actions compared to a throttle-lift included slides. And lifting once over steer has occured doesn't

Anyway, I think that covers it.

Thoughts? Additions?
