Here is my baseline gullwing indoor clay setup. This is for the B6 laydown at OCRC. Generally my setups only need a few changes wherever I go, so hopefully this helps someone out.

A few notables:
- 6.0 rear hex
- 0.5 up on the C block for more antisquat.
- Hub FWD
- Front arm middle hole (this gives better steering feel)
