2008 Caster/Steering ratio/Kingpin offset

[NabilUofL]

I realize there is a lot of geometry that influences steering feed back in these cars, with out going through to much detail or giving away any top secrets; I was wondering what setups teams used in the 2008 competition and how much feedback and arm fatigue the driver felt?

No secrets about it..

Figure out roughly how much steering effort you want at the hand wheel. Say 20 ft-lbf. Use your steering ratios to figure out how much aligning torque that is at the tires.

Use your TTC data (which if you haven't bought.. you should) and figure out how much aligning torque the tires are going to produce. Then adjust caster/mechanical trail accordingly to get the right amount.
