I love Lift-throttle oversteer. Best feeling in the world, IMO. Set up for a corner, turn-in, then lift for a fraction to get the rear to stand up and shift, then back on and through the corner.
Of course, I do a LOT of SCCA RallyCross.
No e-brake needed:

But when it comes to tarmac, letting the rear end out is not the fast way to do things. Keep it tight and don't upset the car for the best times. I'm a little too slide-y for my own good when it comes to tarmac racing and place mid-pack usually.
