Before ordering: Confirm your B9/B9.5 generation, model year, body style and mounting contour. Coupe, Cabriolet, Avant and allroad fitment is not listed. Vehicles outside these years need a separate check.

Material & Package

Genuine carbon fiber with a clear-coated woven finish. Includes one rear spoiler in your selected vehicle version. This is an ASIGN aftermarket accessory.

Adhesive Installation

  1. Test-fit with the adhesive liner intact. Check alignment, full mounting contact and trunk or liftback clearance.
  2. Clean and dry the bonding area using a paint-safe cleaner; remove wax and residue.
  3. Position carefully, peel the liner and press evenly along the mounting area.
  4. Follow the adhesive instructions for application temperature and bonding time before driving or washing.

Before You Choose

Which vehicle option should I select?

Select A4/S4 for Sedan or A5/S5/RS5 Sportback for Sportback. Match the body style, not just the model name.

What if my car already has a spoiler?

Send a rear-view photo before ordering. We will check the mounting area and whether the existing spoiler needs removal.

Can I install it myself?

Careful test-fitting and surface preparation are essential. Choose a qualified installer if alignment or the mounting surface is uncertain.

Will removal leave marks?

Adhesive may leave residue. Removal results depend on the paint condition and technique; repaired or wrapped surfaces need extra care.
