I raced a SRF with the IT cars last year at the 13 hour and also a CCP race at VIR last year in an SRF.

I did get punted by an SM on entry to the pits during the 13 hour, but that wasn't a class specific issue.

I have also raced the 13 hour in an IT car and did not mind the SRF's on the track. I thought we mixed well and had a great time sharing the track.

I know a sprint is a different situation, but I sure would hate to see the SRF's excluded from enduros like they are here in Florida.
