Dunlop Direzza Z1 StarSpec

I see Dunlop is taking a page from the Subaru playbook for nomenclature of top performance models. Anwyay, do any of you know if these are officially legal for ST* class use this year?

as long as they are out and available by April 30th....read rule 13.3 will answer your quesions......you do have the 2008 rule book :)

I thought the date was April 1st. The tire is already being sold, but I don't know in how many sizes. And rather than reading the requirement in the rulebook, then depending on tireRack to tell me how many sizes are currently available (they are almost certainly missing some that are currently available but not online) I figured I'd skip straight to hearsay from the horse's mouth, which is SCCA's ruling on the matter. I asked today because, again, I thought today was the deadline and not the 30th. Additionally, it's only relevant to people running in ST* classes here; everyone running them in other classes can use them as they are already legal under our supps, having been given a UTQG rating of 200. theoretically, I suppose one could claim to be running TST* in order to use them even if SCCA disallows them.

There's no such class in our Region as TST*. All the ST classes must meet the national requirements for Street Touring, including tire eligibility.

I dunno about legality for ST, but I just got mine in a 245/40R17... mmm beefy!
