Details:

Each diffuser fin is reversible giving you 2 style choices to choose from. Diffuser fins are also slotted which gives you the flexibility to set the depth. Pull them out for an aggressive look or push them in to keep it neat and tighten when done.

Diffuser fin profiles can be set before or after installation, adjustment can be done on the car by loosening a few fasteners (refer to fitting diagram).

This 8-piece set includes a pair of adjustable diffuser winglets and a pair of spats for everything to mount to. Everything is pre-drilled and there is no need to remove the rear bumper for installation, only basic tools and knowledge is required.
