HPDE -Time Trials- Racing - Enduro

All makes and models welcome!

Join us at Buttonwillow Raceway for our May event. We have lots of run groups, including High Performance Driver Education (HPDE), Time Trial/Time Attack, Wheel to Wheel racing, and our annual 2 hour Endurance race.  You will get about 2 hours of track time each day. Buttonwillow has great facilities, including RV parking, garage rentals, excellent cafe, showers, a go-kart track, and more.  The grassy areas are perfect for pitching a tent/umbrella and relaxing between runs.  The 3-story tower offers a great vantage point to see the whole track, especially the Endurance race.

Our run groups:

-      HPDE:  For people who have not driven on the track before or who are uncomfortable driving solo.  This will be a highly controlled driving training environment, including classroom and in-car instruction.

-      Solo Group:  Passing only on straights and only with a point-by. This is for people with roughly 1 to 7 track days or who think they would be uncomfortable with less restrictive passing.

-      Point-By Group:  Passing is allowed anywhere on track but only with a point-by.  This is for people who have about 7 to 20 track days.

-      Open Passing Group:  This is for people with 20-plus track days or drivers with race or race school experience.

-      Race:  Wheel to wheel racing action

-      Enduro: Our annual 2 hour endurance race on Saturday. You can drive it all yourself, or with up to two other co-drivers. Entry fee is for the car, regardless of team size. This year’s Endurance event will run from 4 PM to 6 PM, and will include a qualifying session on Saturday afternoon.

We will run the full track, configuration 13, which includes the Bus Stop along the back side. This will level the playing field a bit between the high horsepower cars and the small cars.

Saturday Night Barbecue dinner at the Willow Ranch, 6:30 PM. Bench racing, tall-tale telling, great food & friends! 

Accommodations - Motel 6 Central. Tell them you’re with the Alfa Romeo Club, and code: 453330, to get the Club room rate of $45.99, Single or Doubles.
