No joke, it’s almost time for the
@86challenge doubleheader at Thunderhill West! We’ll be running both directions this weekend, ensuring drivers get to cover every inch of this technical, demanding track. With our own run group and ~40 drivers signed up, it’s sure to be great weekend.
Huge thank you to our partners
@yokohamatire @racetreads @speedsf_track_events for supporting our series.
