The ultimate track diffuser for your Elise & Exige


Diffuser body is 4 inches (10cm) longer than OEM undertray. Fins sit 5 inches (12.7cm) off the ground on stock suspension. Fins run parallel to the ground and extend forward to the undertray to channel air properly out of the rear of the car. This reduced drag and improves downforce. Fins are squared off to keep air channeled inbetween the fins longer, preventing airspill. This diffuser was put to the test by professional Lotus Cup Series racers and autocrossers internationally!

(NOTE: This product DOES NOT fit the rare S260 variant of the Exige)
