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 hander, 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.
