Hey guys,
My name is Will, and I'm a Junior at Lafayette College in Easton, PA. We competed last year at VIR, finished about middle of the pack IIRC...well anyway, myself and another Junior MechE student are doing a chassis/suspension design for a technical elective(since we do not have a team for this year).
One thing I'm wondering about is where some of you guys place the steering rack to eliminate bump steer and keep it out of the way of the drivers shins. On our current car it is hard for tall drivers like me (6'2") to drive it due to my shins hitting the shield that is on the rack.
So we are looking into a floor mounted rack, and we are not sure since our school has always done the rack mounted high up with the tie rod running about 1/2" above the upper a-arm, and basically parallel to that a-arm.
Another thing, I was reading in Milliken that for a floor mounted rack you want the tie rod to attach on the front side of the upright, and the opposite for a high mounted rack. Any truth to this, or does it not matter?
FWIW we will be running a Planar front suspension for next year. We are a very new team, so any thoughts/ideas would be greatly appreciated
Thanks,
Will
