Carbon Fiber Rear Diffuser

Tesla Roadster — Carbon Fiber Rear Diffuser (2.5-Style for 1.5 / 2.0 / 2.5)

Elevate your Roadster’s tail with a true 2.5-style carbon diffuser. Engineered to retrofit 1.5 and 2.0 cars and replace aging 2.5 units, this assembly delivers modern aero styling with perfectly aligned 2×2 twill and a show-grade finish. Each kit includes matching carbon winglets and stainless mounting hardware for a clean, durable install.
Crafted in the USA by a premier composites partner supplying Lamborghini, Ferrari, and McLaren programs.

Why Prepreg & Autoclave Construction

• Maximum properties — Prepreg targets ~35% resin (vs. ~50%+ in wet-lay) for higher specific stiffness and lower brittleness.
• Uniform & repeatable — Pressure + heat cure minimizes voids and print-through; consistent thickness and fit every time.
• Show-grade cosmetics — Tight, symmetric weave orientation under UV-stable Satin or Gloss clear.
• Built to last — Autoclaved laminate resists heat-cycle deformation and road-spray exposure.

Highlights

• 2.5-look retrofit — Updates 1.5/2.0 cars to later visual spec; direct replacement for 2.5.
• Complete kit — Carbon diffuser + carbon winglets + stainless fastener set.
• OEM-style geometry — Produced on dedicated molds to original Tesla dimensions.
• Made in USA — Built by a top-tier carbon shop with supercar pedigree.

*Some early cars may have bracket or heat-shield variations; confirm hardware pack selection at order.

Install & Care

• Lift and support rear; remove OEM diffuser/winglets and hardware. Test-fit CF parts before final torque.
• Use included stainless fasteners; apply anti-seize on threads. Verify exhaust/undertray clearances.
• Rinse road salts/debris regularly; clean with pH-neutral wash. Avoid abrasive pads and harsh solvents on clearcoat.

Every Gruber carbon component is produced on precision tooling to original Tesla specifications, delivering factory-grade fit with elevated materials and finish.
