Here are my TOP Rebel 12 setup sheets from the 2015 US Indoor Champs in Cleveland:
I ran both 13.5 and Mod at USIC. Setups were very similar between both cars, but with the wide front end on the mod car.
With the new CRC carpet there was a lot of grip, which meant that everyone was running very small tires and gluing front sidewalls. My cars were still a little bit tippy if I was too aggressive, but overall they were fairly easy to drive. If anything, I think the 13.5 car wasn’t aggressive enough, as it seemed to lose ‘cut’ as the weekend progressed.
I finished 8th overall in Mod and was in the B with 13.5 (disappointed, yes.)
