FAQ about this diffuser

Our 2nd most popular diffuser for the Elise & Exige!


Diffuser body is 2 inches (5cm) longer than OEM undertray. Fins sit 5 inches (12.5cm) off the ground on stock suspension. Fins run parallel to the ground and extend forward to the undertray to channel air properly out the rear of the car. Fins are finished with squared off edges. This keeps air inside the fins and prevents air spill, reducing drag and improving downforce. This diffuser has slightly better performance than our 5-Element Rounded Rear Diffuser for Elise & Exige!

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