which we are 'blessed' with, has some peculiar characteristics that make the cars livelier than average in lift-throttle situations. the main one is the camber change with suspension travel. when the suspension is compressed (under acceleration), it creates a bit of negative camber, which along with the weight on the back helps really plant the car in the corners. the problem arises under extension, when weight is transfered forward: positive camber. what happens when you lift in a corner is that not only does the weight go forward, but the outside rear tire is tilted on its edge, reducing the contact patch. this is as bad as it sounds, and should be avoided. the solution? always corner under power. get all the braking done before the corner, set the entry speed, and then feed the throttle in progressively throughout the turn. if you enter in the correct gear, there shouldn't be any reason to shift. if the onramp is long enough to require a shift, chances are the curve is pretty gentle in which case while the shift does unsettle the car a bit, if you're ready for it it's not a big deal.
