Question 1
You are competing in a circuit race and you car is fitted with a brake bias control. The heavens open and the circuit is wet within seconds and you're on a dry set-up. The only thing you are able to change is the brake bias, shoudl you.

a) Wind on more rear brakes
Wind on more front brakes

Question 2
Stiffening your front anti-roll bar will usually make the car tend more towards :

Oversteer

Question 3
Bump steer is :
