Look there are some semi slick style tread patterned summer/high performance street tyres, do you also want an "R" racing compound semi that is also street legal? see tyre bit of http://www.skylinesaustralia.com/forums/topic/416539-2013-sau-vic-motorsport-championship/
I must admit that I'm looking for 2nd hand R type semi slick(web searches and ringing around the dealers who specialise in motorsport tyres), because I only have one set of rims and wish to determine what size rims I'll get for 2nd set, I want to check out a set of R types on current rims before I determine if 2nd set will be wider etc As I've only one set of rims why pay $500 per tyre to waste rubber/heat cycles on street driving between events. 2nd hand tyres should see me through enough events to make a decision. If I find a good shop I can PM you.
FYI I've been runnings Yoko AD08s for a couple of years, 15-20 events, see youtube in sig. They last a track sprint session without going squish(others say same of 595rsr), most high performance street tyres don't.
