The main track at Willow Springs Raceway, informally called the “Big Willow”, consists of 9 turns. The layout is built for speed, but combines speed with turns and elevation changes to offer a unique challenge. It is possible for a capable car or motorcycle to exceed 160mph on the front straightway.
- Turn 1: “Castrol corner” is a 90 degree high speed left-hander.
- Turn 2: “The Rabbits Ear” is a double apex sweeper
- Turn 3/4: “The Omega” is an uphill and downhill section with camber change, this is the most technical segment of the layout
- Turn 5: A quick left-hander that sets up for the fastest sections of the track
- Turn 6: “Monroe Ridge” is a gradual bump. It is common for fast riders on higher powered motorcycles to lift the front wheel over this downhill section. A good line and drive through this turn is essential for a good lap time.
- Turn 7: “Repass Pass” – a slight bend in the track.
- Turn 8: High speed right hand corner. The lead in to this turn is the fastest section of the racetrack and coupled with the turn itself – probably the most critical for a good lap time. It is also the fastest turn on any racetrack west of the Mississippi River.
- Turn 9: Decreasing radius right harder, with a big dip right before the apex. A good line through this turn is crucial for top speed on the front straightway to the start/finish line.
