Buttonwillow Raceway Park (Configuration 13) (CW)

Buttonwillow 13 CW is a proper rhythm circuit: an early stop‑start pinch at corner 3 leads into a relentless run of fast, linked sweepers from 7 through 13 that keeps the car loaded. Lap time hinges on the mid‑lap engine‑room—corners 10, 12 and 14 are the big tickets—before the sting in the tail where corner 17 shapes the final sector and corner 18 carries you onto the straight. It’s a layout that prizes stitching together mid‑speed transitions with few breathers once you’re past the opening complex.
