Lamborghini Urus Prepreg Dry Carbon Fiber TC Rear Diffuser

Engineered for Lamborghini Urus owners, this Prepreg Dry Carbon Fiber TC Rear Diffuser upgrades the rear underside of the world's fastest super-SUV to the aggressive TC look and raises its aerodynamic character. Manufactured in Europe and quality-controlled by BYC Performance, this Urus TC carbon rear diffuser bolts directly to OEM rear bumper mounting points.

For the Lamborghini Urus with its 4.0L V8 biturbo engine and 650-666 hp output, this diffuser completes the TC rear kit aesthetic and, when used together with the TC Rear Air Duct Add-on (upper rear area), delivers a unified aggressive look across the entire rear face. Autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay parts, with superior structural integrity and outstanding UV resistance.

Key Features

• Prepreg Dry Carbon Technology: Cured in an autoclave under high heat and pressure for a more consistent weave.
• TC Style Geometry: Aggressive TC rear kit contours with vertical channel ribs and integrated exhaust cutouts.
• Lightweight Build: Noticeably lighter than the factory plastic diffuser.
• Aerodynamic Build: Channeled diffuser surfaces convert underbody airflow into rear-end stability.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• TC Kit Compatible: Pairs with the TC Rear Air Duct Add-on, TC Front Lower Lip, TC Front Upper Lip and TC Spoiler.
• UV & Chemical Protection: Clear coat resists exhaust heat and road chemicals.

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

Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature — leaving voids and inconsistent weight. Prepreg (dry) carbon:

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

Vehicle Fitment

This Urus TC carbon rear diffuser fits the following models:

• Lamborghini Urus (2018, 2019, 2020, 2021, 2022) — 4.0L V8 biturbo, 650 hp
• Lamborghini Urus S (2022, 2023, 2024) — 4.0L V8 biturbo, 666 hp
• Lamborghini Urus Performante (2022, 2023, 2024) — 4.0L V8 biturbo, 666 hp, lifted

Important notes:

• This product is NOT compatible with the Lamborghini Urus SE (2024+ facelift, PHEV). The 2024 facelift changed rear bumper geometry; the TC kit is designed around the pre-facelift Urus rear bumper.
• This product is NOT compatible with the Porsche Cayenne 9YA, Audi Q8 or Bentley Bentayga. They share the MLBevo PL52 platform with the Urus but use different rear bumper and diffuser geometry.

Installation Notes

Urus TC rear diffuser installation involves removing the factory diffuser/lower panel and bolting on the new carbon diffuser. Professional installation is recommended.

1. Raise the vehicle and remove rear bumper underbody screws.
2. Detach the factory lower diffuser panel from clips.
3. Test-fit the new TC carbon diffuser for alignment.
4. Verify exhaust tip alignment with the diffuser cutouts.
5. Secure with the supplied hardware to the manufacturer's recommended torque.
6. Confirm that all clips have fully engaged.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer nozzle at least 30 cm from surface. Inspect areas near the exhaust tips periodically.

FAQ

Compatible with base Urus, Urus S and Urus Performante?
Yes. All three trims share the same pre-facelift rear bumper geometry.

Compatible with Urus SE (2024+ facelift)?
No. The facelift changed the rear bumper, so the TC kit is incompatible with SE.

Used together with the TC Rear Air Duct Add-on?
Yes. The TC Rear Air Duct Add-on mounts in the upper rear area; this diffuser sits at the lower rear. Together they deliver a unified carbon rear face.

Compatible with Porsche Cayenne or Audi Q8?
No. Despite the shared MLBevo PL52 platform, rear bumper and diffuser geometry differ entirely.

Will rain damage dry carbon parts?
No. Autoclave-cured prepreg carbon is fully waterproof and weather-resistant.
