Hi :) Effects on suspension/steering are nicely and clearly explained. My question is, why setup some bump-steer rather than dialing in more lock at the radio wheel when driving it? My right hand has more impact than bump-steer on the angle of the wheel when driving than dialing in some bump-steer, doesn't it?
It really comes down to driving style. At some point, you can only dial in so much lock. If you want to change the way the car steers as it is cornering, then bump steer is a tuning option.
