It would be street class, depending on tyres.
Reason being it's still using a RB25, just converted. So the factory engine that has been modified, and engine modifications are unlimited for street class. Just excludes non-factory motors. So putting in a LS1 for example.
Not for the S'n'S it isn't
But given what other forums are bringing along (basically super-lap cars). SAU must fight fire with fire of course
Hopefully superjet is coming down to run some 8-sec passes. He will confirm back in approx 2 weeks but unless something really goes wrong - it'll be down here.
It's going to be a great spectator event i reckon. 3 days of all levels/types of motorsport to tickle everyone fancy in one way or another
