C3 Carbon Ferrari 458 Carbon Fiber Rear Diffuser

FITS: Ferrari 458 Italia

Replace the heavy fiberglass diffuser on the rear on your Ferrari F458 with a lightweight, beautifully crafted Carbon Fiber Rear Diffuser from C3. The hefty, drably painted OEM diffuser belies the Formula 1 roots of the 458, adding unnecessary weight aft of the rear axle. Ferrari offers a carbon replacement for $9,600! C3 makes an autoclaved, pre-impregnated 3k dry carbon fiber replacement for a reasonable price with no compromise in quality, fitment or finish. C3 has perfectly matched the OEM Ferrari 1x1 3K plain carbon fiber weave; both functional and beautiful, this is our most popular upgrade for the 458.

A common complaint among 458 owners about the factory diffuser, which breaks easily, is that it's easy to break in daily driving. The C3 Carbon Fiber diffuser, by comparison, is far more robust. However, should any of the diffuser fins on our piece get scuffed or chipped, they can be easily replaced individually!


  • Autoclaved pre-preg dry carbon fiber 1x1 3K plain weave that matched to factory Ferrari carbon
  • Weighs 67% (over 10 lbs.) less than the factory Ferrari piece
  • Clear-coated with automotive urethane, hand polished to a mirror finish
  • OEM-perfect fit with ground clearance equal to the original factory diffuser
  • Installs easily in minutes with no modification to your 458
  • Digitally 3D laser scanned for guaranteed fitment
  • Autoclave formed in billet aluminum molds at more than 100 psi and 200 degrees Fahrenheit

Experience the Difference of C3 Carbon Products

Competition Carbon Components (C3 Carbon) has been steadily gaining in popularity amongst today’s high-performance driving enthusiasts due to several key factors that help C3 Carbon stand out in a market full of sub-par aftermarket offerings. Each C3 Carbon product is manufactured to provide perfect fit and extreme strength while reducing weight, maximizing quality and ensuring years of exceptional finish. We provide all of this for significantly less money than OEM parts.

Every product we make uses pre-impregnated dry carbon formed in a CNC-machined billet aluminum mold which is manufactured by laser-scanning the OEM component(s) so you know you’ll have a perfect fit, every time. Dry carbon is stronger and lighter than wet carbon, often weighing 1/3 of our competitors’ products. Our manufacturing methods also produce a smoother surface on each part for more dimensional accuracy; shaving edges, widening mounting holes and flexing pieces to make them fit are a thing of the past.

C3 Carbon also applies an automotive urethane clear-coat which is U/V cured for durability and guarantees C3 Carbon parts won't yellow over time.

Many of our competitors use wet carbon (which is heavier), and some use fiberglass with a carbon overlay (much heavier, as the carbon fiber has epoxy literally painted onto it). These materials and manufacturing methods produce a poor finish due to air contamination, and because the epoxy isn’t applied uniformly throughout the weave. These products are also much weaker than C3 Carbon products. Finally, most competitors use a fiberglass mold, which is far less expensive but cannot maintain the strict tolerances we demand of our own products. In the end, the fit and finish simply cannot stand up to C3 Carbon products.
