Lamborghini Huracán Coupe Sidewall Right Bianco Icarus

Right Sidewall (also commonly known as the Rear Quarter Panel) for a Lamborghini Huracán Coupe is one of the most significant structural and cosmetic components of the car’s aluminum spaceframe.

Sourcing this part in Bianco Icarus (LY9K) usually implies looking for a used/salvage panel, as new parts are supplied only in primer.

1. Technical Identification

• Part Number: Primarily 4T0809602 (with varying suffixes for different model years/EVO updates).

• Material: High-grade Aluminum.

• Construction: Unlike the front fenders, which are bolt-on, the rear sidewall is a large structural piece that integrates with the roofline and the door sill.

• Color Code: LY9K (Bianco Icarus Metallic).

3. The “Bianco Icarus” Paint Challenge

Even if you find a used panel in Bianco Icarus, a direct “bolt-on” and drive is rarely perfect:

• Metallic Flake Match: LY9K is a metallic finish. The orientation of the flakes can differ based on how the panel was sprayed at the factory vs. another batch.

• UV Fading: Depending on where the donor car was kept (e.g., Arizona vs. London), the white may have aged differently than your car.

• Recommendation: Most 2026 specialist body shops will still require “blending” the new panel into the door and the engine cover to hide the transition.

4. Installation Complexity

• Bonding & Riveting: The Huracán’s rear sidewall is not just bolted on. It is part of the aluminum spaceframe and is typically structurally bonded (glued) and riveted.

• Labor Hours: A full replacement of a rear sidewall usually requires 30–50 hours of labor, including the removal of the rear glass, the interior trim, and the engine bay components.

• Total Repair Cost: Expect a total bill (Part + Paint + Labor) between $12,000 and $18,000 at a certified Lamborghini collision center.

5. Essential Sub-Components

When replacing the right sidewall, you will likely also need:

1. Rear Quarter Glass: Often breaks during removal.

2. Air Intake Duct (Right): The plastic or carbon fiber scoop that feeds the engine.

3. Wheel Arch Liner: Typically damaged if the sidewall was hit.
