Here is my setup from last weeks Exotek Scale Champs at Cal Raceway. It's based on Chris Mitchell's setup but with some tweaks for the a very unique track condition: it is a small, bumpy and high grip track, with a changable layout. 21.5 Motors with GT bodies and tires.

This race had a very wide open layout with a 2 sweepers, a very fast chicane, carousel turn and 1 hairpin, resulting in 9.8 sec lap times. The main things i focused on were quick left-right-left transition through the chicane to keep full throttle (would have liked to try a 1.3 front sway bar too but I only had 1), and corner speed around the carousel and hairpin (-1.5 rear toe and -1.5 rear camber).

Also needed to have it handle the bumps better, which the increase in front caster helped.
