I'm keen to join in on the GT class, but I don't see which ruleset you're using. Is it the same as the SERCCC ruleset where it's a spec Muchmore motor and Volante 36 tires? I've been running an LRP 17.5 at SERCCC and don't really want to buy a motor just for this event, and since SERCCC is relocating and changing their race schedule I won't be able to use it there either. Would I be able to run this motor?
(There's also some debate over whether my body is legal, but they've let me run it anyway. It's the gold Porsche Le Mans body pictured on the SERCCC GT class page)
