FORM Pre-Preg Carbon Fibre Competition Rear Diffuser for Audi R8 by FORM (2015+, 4S)

Take the rear end of your Audi R8 to the next level with the Pre-Preg Carbon Fibre Competition Rear Diffuser from FORM. Engineered to replace the factory lower bumper section, this diffuser improves underbody airflow while delivering a dramatic, motorsport-inspired rear silhouette.

Key Features:

• Direct OEM fitment — retains factory mounting points, wiring connectors, and sensor cut-outs where applicable
• Improves underbody air extraction for reduced rear lift and improved stability
• Aggressive vertical fins add visual width and motorsport presence
• UV-stable clear coat prevents yellowing, fogging, and weave degradation over time
• Autoclave-cured pre-preg carbon fibre construction for a consistent 2x2 twill weave and show-quality clear-coat finish
• Backed by FORM Industries — a trusted name in OEM-level aftermarket upgrades for modern performance cars

Materials & Construction: This component is produced from genuine pre-preg carbon fibre — the same autoclave-cured composite process used in Formula 1 and OEM performance parts. Unlike wet-layup or hand-laid alternatives, pre-preg delivers a tighter, more consistent weave, superior strength-to-weight ratio, and a show-finish gloss clear coat with full UV protection. The result is a part that looks as good in five years as it does on day one.

Fitment Notes: Built to suit the Audi R8, model years 2015+, 4S. This is a direct-fit replacement or overlay depending on variant — the part matches the factory mounting pattern and panel geometry of the listed models, so a standard install is bolt-on / clip-on with no cutting or drilling required. If your car was built with a non-standard options pack, it's worth checking fitment with our team before ordering.

Installation: Fitment is straightforward for an experienced installer using standard hand tools. We strongly recommend installation by a qualified bodyshop or detailer, particularly for exterior components that require panel alignment, adhesive bonding, or painted-surface preparation. Full fitment guidance is provided in the box, and our support team can help confirm the best approach for your specific car.
