Goal is to reduce (front) caster from stock 20 degrees, to 16 degrees, to improve steering on the track.
@Overkill
Some options:
1. Trim the stock arms on the front hinge pin area by about 5 mm, so the arms (and pillow ball) can be moved forward 5 mm.
AR330215 stock
AR330215 trimmed
2. Get a longer suspension mount that moves the rear hinge pin location outwards by about 2 mm on each side. This will swing the pillow ball about 5 mm forward.
Set to 61 mm eye-to-eye:

AR330379 Font-Rear Suspension Hanger is second from the top:
Extended
3. Design and 3D print a custom front suspension arm that has the same hinge pin geometry, but sweeps the pillow ball forward by 5 mm.
One of the guys at the track did this, will check in with him for more info.
Are there any other options out there?
