I will let somone on the board correct me if I am wrong on anything I am about to state. Otherwise here is what info I have gathered from other posts recently.

Super street riders are not ever allowed to participate in the MRA racer practice sessions.

Superstreet riders can do the previous friday track day to an MRA race weekend with the exception of the very first race of the year which is exclusive to racers with MRA licenses.

So in summary for this weekend coming up, it sounds like the only track time available for you would be with the instructors during the Super Street program.

In future rounds Friday would also be open.
