The second Formula USA Unlimited Superbike race at Willow Springs ended with a red flag on lap nine of 12 with Shawn Higbee the leader and the declared winner. Ken Chase was second and defending Champion Grant Lopez third.
The red flag was caused when Greg Leffler highsided in the turn six area and needed medical attention in an impact zone.
While leading, Lopez ran it into turn eight a little too hard and lost the front end, sliding along on his knee before saving it at the edge of the track and taking up the chase in third.
In the earlier Buell Lightning race, Justin McReynolds beat Michael Barnes and Tripp Nobles.
In the Aprilia Cup Challenge race, Dan Fischer was given the win in a line call over defending Champion Aaron Clark, followed by Jeff Wood, Derek McKelvie King and Vicky Jackson-Bell, all five having been involved in the race-long battle for the lead.
