Full Version: Lift-off over-steer and braking transitions

Without dwelling over past topics relating to "lift-off over-steer" i do wonder and welcome answers if brake bias could reduce or even belay this phenomenon?

My thoughts are transition entry in and a rear bias to induce "squat" prior to inertia weight transfer.... What do you think "squat or push?"

I wouldn't have thought bias would be the ultimate answer. Too much front and you're just going to push wide and reduce your overall braking ability. Things like wandering a light tail into a corner is a natural part of weight transfer and anything you do to help that with the chassis will ultimately compromise you in other areas. As always it's finding the best compromise for the driver smile.gif

You have to get yourself to some trackdays tony so you can feel all this first hand. The MR2 is great for wandering the rear into the bends... http://www.youtube.com/watch?v=QSxHvlDMwTA laugh.gif

I have read somewhere that some race cars do allow the driver to adjust the brake bias to help in these situations.
I'll have a dig around and see what I can find. (It's probably in Speed Secrets, Professional Race Driving Techniques by Ross Bentley as I'm re-reading that at the moment.)
