I just received this email:
Hoosier Super Tour Competitors:
Please be aware that registration for the March 24-26 Hoosier Racing Tire SCCA Super Tour event at Circuit of the Americas will open at 6 p.m. Central Time on Sunday, February 19. Initial registration for this event will be capped at 50 cars per Group. Entries will be accepted on a first-come, first-serve basis. After the cap has been reached within a Group, a waiting list will be created and additional drivers may be allowed to register pending paddock space. Wait-listed drivers allowed to register will be contacted no later than five days after registration opens.
Spec Miata and the SRF/SRF3 Groups may be allowed up to 75 entrants depending on availability of paddock space. All other Groups will remain in the 50 to 60 competitor range due to space restrictions.
Please plan ahead and prepare to register Sunday if you plan on competing at the March 24-26 Hoosier Racing Tire SCCA Super Tour event at Circuit of the Americas.
There is not a test day scheduled for this event.
Registration for this Lone Star Region event will be on MotorsportReg.com (this is a change so I'm notifying my SM buddies here).
