• All are engineered for weight savings and performance while enhancing style.

Installation Tips

• Align precisely with underbody and exhaust flow; avoid contact with tires or suspension.

• Use recommended fasteners or high-strength adhesives per model instructions.

• Ensure sensors, tow hooks, and heat shields remain unobstructed.

Care Tips

• Clean with mild soap and water; avoid harsh solvents that can degrade resin.

• Inspect mounting points regularly for cracks or loose bolts.

• Install protective rock guards where available to shield against debris.

Fitment Verification

• Confirm year, trim, and bumper configuration before ordering.

• Check compatibility with adjacent aero parts to avoid gaps.

• VB Carbon offers model-specific fitment guides and customization options.
