We were DQ'd at Thunderhill for running 245 square.. LOL (we didn't care, we were testing for next year)
and would have probably been DQ'd at WSIR a week or so back if we hadn't popped an engine on Sat.
The 245 square is MUCH faster at WSIR. Within a few laps on Sat. we would have qualified 2nd only 2/10ths off no.1 qualifier.
The square setup on 255's or 245's requires a completely different bar setup and completely different camber settings.
We have been running 255 square with PCA club racing for several years now. ALL the track records across the USA have been set on 255 square 888's.. then reset when they went to 255 square RA1's.
