A 1/4 inch ABS Base Plate and Aluminum Composite Material (ACM) Fins make a strong yet lightweight rear diffuser.  The base comes in natural back finish and the Fins are painted black with thin silver edges that draw your eye.  Fins are also easily replaceable in case of accidental damage.  Bolts through blind holes in the top of the fins keep them firmly attached, with a bonus of no visible fasteners or angled mounting plates!  Purchase includes all mounting hardware and instructions.  

Diffuser's are designed to fit a specific bumper.  IF you are running a termi bumper on a GT you will you want the termi diffuser, etc

This product will work with a solid axle or an independent rear. Will not work with a sumped tank.

    Mach 1 diffuser

    This part fits perfectly. It's that little extra piece that gives the rear end of these cars the pop they need to break the mold from every other new edge. Highly recommend this product!

    Rear Diffuser

    The rear diffuser for my 04 GT came in as described. Install is pretty simple and takes about 30 mins. The look is very very nice! Completely changes the rear end of the new edge mustang. I highly recommend this accessory!
