Being beautiful and functional, it's not often tied together in the performance aftermarket world but it's proven here. The Velox Motorsports rear diffuser for the ND Miata reduces lift, reduces drag, and improves the cosmetics of the vehicle. By using CFD, we were able to improve performance of the diffuser while keeping it in a specific build volume for daily and track use. The unit is adjustable vertically to fit multiple aftermarket exhausts. Produced from aluminum, the unit can take quite a beating and still retain it's functionality and shape.
