Strap in—the Tire Rack SCCA® Time Attack Challenge Series is heading to Buttonwillow Raceway Park for a no-holds-barred weekend alongside the Global Time Attack Finale, where the series championships are decided, lap records are hunted, and the season comes to a full-throttle close.
Located in California’s Central Valley, Buttonwillow Raceway Park is home to CW13—the de facto Time Attack configuration on the West Coast. Fast, technical, and relentlessly demanding, CW13 is the benchmark layout for chasing outright lap time. Its mix of high-speed sweepers, late-braking zones, and critical corner exits rewards precision, commitment, and a well-dialed setup. If you want a layout that tells the truth about both car and driver, this is it.
Want to know where you stand? Buttonwillow has long been a measuring stick for Time Attack performance, and with National Time Trial competitors sharing the weekend with the Global Time Attack Finale, the competition will be fierce. Whether you’re chasing a Personal Best, battling for class honors, or looking to finish the season strong, this is the place to put it all on the line.
Kicking things off early, Friday features a dedicated Test Day / Track Day, giving participants valuable seat time to shake down new parts, fine-tune setups, and dial in their cars before competition begins. It’s the perfect opportunity to arrive confident and ready when it counts.
When the sun drops and the engines cool, Buttonwillow’s legendary paddock culture takes over. Set up camp, compare data, bench race with friends, and replay the laps that mattered most—because at events like this, the stories don’t end when the track goes quiet.

Register now and join us at Buttonwillow Raceway Park for a weekend of all-out performance, precision driving, and championship-level intensity with the Tire Rack SCCA® Time Attack Challenge Series and the Global Time Attack Finale.
