Horse wrote:Serious Q: using the trail braking, how is body roll and grip managed at the transition to drive?
I've been playing more with this recently.
There's a period in the corner where you really aren't doing much at all -- the steering has taken a set (following Dave's steps, you've turned in enough until you've got to the line), and the braking has dropped to just a trailing throttle - the car is settling back onto its haunches off the braking: the reduction in the braking is what settles the weight, not the start of the acceleration. In a long enough corner it's nice to drift up to a neutral throttle to counteract drag, or if it opens up sooner then that can be a rising throttle.
The weight seems to just flow backwards as long as this transition is done subtlely and in line with decreased braking effort: you can't just jump on the throttle like you can for a more classical approach. I've not noticed a lot of roll change: this is probably dominated by the cornering.
Grip shouldn't be much of an issue provided things are managed smoothly -- the power is going on at the slowest point and the move from standing on the nose to being nicely balanced increases the overall grip. The crisis of grip has already happened at turn-in.
