From Exotek Racing:
Our new caster setting tool for the Exotek F1ultra. Provides easy to read ‘pointers’ that tell you the caster degrees of the front steering knuckles when used with 1/10 TC type camber set up gauges as shown.
Works with Hudy, Arrowmax, Integy and similar 1/10 TC set up stations (required, not included).
1 pair of finely machined alloy units that simply slides onto the stock F1ultra axles.
Remember- the forward turnbuckles adjusts camber and the rear facing turnbuckles adjusts your caster.
