Our new s197 rear diffuser fits GT bumpers. The Base is constructed 1/4 inch ABS plastic while the Fins are made from an Aluminum Composite Material (ACM) this gives the fins a high quality smooth black finish. The diffuser does not need to be painted and will never rust. In the event of damage the Fins are easily replaceable with screws going into the top of the fins giving our diffusers a very clean appearance. Purchase includes all mounting hardware.  UPDATE, we have confirmed fitment through 2011 body's!

    05-11 diffuser looks perfect

    Installed on my 2008 Bullitt, looks absolutely amazing. Exactly what the car needed to finish off the rear end. Fit perfect, excellent craftsmanship. This is the second vehicle I’ve installed a C2 diffuser on, and I’ll do it again if I buy another mustang in the future.
