A pair of FRP diffuser panels designed to bolt to the rear bumper and sharpen the lower fascia line. Built from fiberglass-reinforced plastic, these add-ons ship in raw FRP condition so you can finish them to match your paint. Two-piece set installs at the factory mounting points.
Will these diffusers block or obstruct my factory sensors or backup camera?
The diffusers mount below the main bumper surface and do not interfere with factory sensor locations. If your vehicle has sensors integrated into the rear bumper fascia, verify their exact positions before final installation to ensure clearance.
How much prep work is required before painting?
Sand the surface with appropriate abrasive, clean thoroughly, and mask off any areas you don't want painted. Apply your chosen primer and topcoat system following standard automotive finish procedures. The FRP substrate accepts paint well once the factory primer is properly prepared.
Do these add-ons extend beyond the factory bumper edge?
The diffuser profile adds visual depth to the lower bumper area without creating a significant overhang. They integrate with the existing bumper line and do not extend far enough to affect parking clearance or trailer access. Verify fitment in your specific setup before finalizing placement.

It's designed for the fitment listed on this page. If your model has multiple bumper options (M Sport, GT, RS), confirm which one you have before ordering — these are specific to the bumper style.
Most ship unpainted (raw composite, primer, or raw carbon). Some carbon fiber lips ship pre-finished with clear coat. The spec sheet on this page tells you what to expect.
Yes — most lips and diffusers are bolt-on or 3M tape-on, 30-90 minutes with basic tools. Some require drilling, which is permanent, so check the spec sheet for the mounting method before you start.
Most lips and splitters ship standard parcel (UPS/FedEx). Larger one-piece splitters may ship freight. Either way, shipping covers insured delivery and damage replacement.
Duraflex has been the go-to aero choice for serious builders for over 20 years. These parts are flexible fiberglass pieces engineered to be shaped, prepped, and painted to your exact spec. If you're doing a proper build with body shop work planned, this is the right part.
Parts ship unpainted and require professional prep, prime, and paint before final installation. Minor adjustments during fitting are normal and expected, this is how custom builds get a factory-quality result.

Yes. Duraflex parts are engineered for professional prep, prime, and paint. They're built for builders doing a proper custom finish. Your body shop has almost certainly worked with Duraflex before, it's the most widely used fiberglass aero brand in the aftermarket.
Your shop will sand, test-fit, smooth any minor imperfections, prime, and paint to your exact color spec. Minor waves or uneven edges on raw fiberglass are completely normal and are addressed during prep, this is standard for any custom aero build.
Duraflex parts are designed to fit within acceptable custom aero tolerances. Because they're flexible fiberglass rather than OEM plastic, minor adjustments during fitting are normal and expected. Your body shop will dial in the gaps during the test-fit stage before paint.
