Fast ratio arms AND a borgenson box will make for some serious fast ratio steering. Faster than current production cars I believe.

Borgenson is roughly 14:1
Fast ratio arms make a 16:1 stock ratio 12.7:1.

Im going to take a wild guess estimate without calc'ing anything out that you'll get 10:1 or something steering. Is there some modern car you've driven with that ratio to compare to?

Why 3.23 gear ratio with Gear Vendors? That would seem like really lugging the motor on the highway.

What tire size you running back and front?
