Audi S5 / A5 B9 / B9.5 | Prepreg Dry Carbon Fiber Front Lip

Audi S5/A5 B9/B9.5 Prepreg Dry Carbon Fiber Front Lip

Designed for Audi S5/A5 B9 and B9.5 owners, this Prepreg Dry Carbon Fiber Front Lip adds a lowered, aggressive look and front-axle aerodynamic benefit to your car. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this Audi S5/A5 carbon front lip mounts directly to the OEM front bumper lower edge on both B9 pre-facelift and B9.5 facelift coupés, sportbacks, and cabriolets.

If you're building an Audi A5/S5 B9 tuning project and want a track-grade front-axle visual statement, this dry carbon front lip is for you. Autoclave-cured prepreg carbon is noticeably lighter than wet-lay parts, with superior strength and excellent UV resistance. Complements the S5 B9/B9.5's 3.0 TFSI V6 single-turbo (349-354 hp) and the A5's 2.0 TFSI EA888 character with an aggressive front-end accent.

Key Features

• Prepreg Dry Carbon Technology: Pre-impregnated plies cured in an autoclave under high heat and pressure, homogeneous resin, a consistent weave.
• Lowered Front Profile: Adds low-stance presence to the front bumper lower edge.
• High Strength: Carbon fiber offers very high strength for its weight; resists light contact and road debris.
• Aerodynamic Edge Line: Accelerates air close to the ground at the front axle, contributing to front downforce.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• B9 + B9.5 Dual Fit: Mounts to Audi A5/S5 B9 (2016-2019) and B9.5 (2019-2024) OEM front bumper lower edge.
• UV & Chemical Protection: Long-life clear coat resists fading, cracking, and road grime.

Prepreg Dry Carbon vs. Wet Carbon: Which Is Better?

Most aftermarket carbon parts use wet lay-up, where resin is applied by hand and cured at room temperature, which can leave air voids and inconsistent weight. Prepreg dry carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• Made with a controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use

Installation Notes
