2016 Rocket Pop Steering

[Jason]

Rocket Pop our 2016 Detroit Kart, and first official kart had some pretty solid steering. Some of the details include.

Front wheel disc brakes
10 degrees KPI (King Pin Inclination) or SAI (Steering Axis Inclination)
0 Camber
Fully adjustable Castor
Slight Toe In Bias
Basic Ackermann triangulated to the center of the rear axle.

The entire axle bolts in based on two U-Bolts, this is what gives the adjustable castor. We welded on a tab with multiple bolt holes to lock it in. The spindles were made out of hex shaped couplers with brash bushing pushed in. We CNC'ed our Ackermann arms/tie rod end mounts and other gussets. This could be done by hand though.
