Dick;
If you have much bump steer in the front (or rear) suspension, you'll be
driving an evil-handling car. No doubt about that! Especially avoid toe-in
at the front on bump and toe-out at the rear on bump. Droop is less
important.
True, if there were a perfectly straight and level run without any wind, a
car should run straight even if the suspension is totally hosed-- providing
all four wheels are pointing in the same direction-- but this is only a
theoretical case. Cars never run perfectly straight and level; a driver is
constantly making small steering corrections to keep the car going
"straight" and if those steering corrections make the car want to swap ends
(unstable), it will be a white-knuckle ride.
Make the car as good- handling as possible by suspension geometry, CG, etc.,
then work on aerodynamics. That's my philosophy, anyway--- others may have a
different opinion.

Subject: Bump Steer
I'm building my '53 Studebaker with a target for 200 MPH. How important is
bump steer in LSR? It seems that if the car is being used on a straightaway
only, and it's a pretty smooth surface, bump steer shouldn't be a big
factor. I was toying with the idea of a one piece tie rod with independent
front suspension.
