High-Kick Profile · Gloss Wet Carbon Fiber · Adhesive-Mounted

Give Your Audi A4 or S4 a Sharper, More Aggressive Rear Profile

This high-kick rear spoiler adds a pronounced performance-inspired edge to the trunk without replacing the factory trunk lid. Its gloss wet carbon fiber construction delivers visible weave, reflective depth, and a clean OEM-plus finish designed specifically around compatible sedan body lines.

Real Carbon ConstructionGloss wet carbon fiber with visible woven texture

High-Kick StylingA more assertive profile than a subtle lip spoiler

Model-Specific ShapeMolded for the listed Audi A4 and S4 sedan fitments

No-Drill InstallationAdhesive-mounted add-on design for the trunk lid

Why It Changes the Car

More Visual Impact Without an Oversized Wing

A factory trunk line can look understated, especially after other exterior upgrades. The raised high-kick contour adds definition from the rear and three-quarter angles while keeping the design integrated with the sedan’s original proportions.

Stronger Rear Stance

The elevated outer profile creates a more planted and performance-focused appearance.

Deep Gloss Carbon Finish

The reflective clear-coated surface highlights the carbon weave under daylight and garage lighting.

Reversible Exterior Upgrade

The spoiler installs as an add-on rather than replacing the trunk lid or requiring drilled mounting holes.

Material and Finish

Gloss Wet Carbon Fiber

What You See

A real woven carbon fiber appearance with dimensional depth, a smooth glossy surface, and a performance-oriented finish.

What to Expect

Carbon weave and clear-coat appearance may show minor natural variation between pieces. Inspect the spoiler before installation and complete a full dry test-fit first.

Fitment Guide

Sedan Body Style Only

Choose the option that matches the chassis generation shown below. Do not select by model name alone.

Vehicle	Model Years	Chassis	Body Style
Audi A4	2009–2012	B8	Sedan only
Audi A4	2013–2016	B8.5	Sedan only
Audi A4	2017–2025	B9 / B9.5	Sedan only
Audi S4	2018–2025	B9 / B9.5	Sedan only

Important: This listing is not intended for Avant, Allroad, wagon, Coupe, or Sportback body styles. For the North American market, S4 compatibility begins with the 2018 B9 model year. Vehicles with an existing factory or aftermarket trunk spoiler should be photo-verified before ordering.

Use One Combined Vehicle Selector

To reduce incorrect combinations, use a single option named Vehicle instead of separate “Model” and “Year” selectors.

Installation

Adhesive-Mounted, No Drilling Required

Careful preparation and alignment are essential because the spoiler spans a large section of the trunk lid. A two-person installation is recommended for the cleanest positioning.

Test-Fit
Place the spoiler on the closed trunk and confirm edge alignment before removing any adhesive liner.

Clean
Wash, degrease, and fully dry the mounting surface. Remove wax, polish, dust, and moisture.

Warm
Install in a warm, dry environment. Gently warm the adhesive and mounting surface when conditions are cool.

Align and Press
Center the spoiler, lower it evenly, and apply firm pressure across the full bonding area.

Allow to Bond
Avoid washing, heavy rain, or high-speed driving for at least 24–48 hours after installation.

Installation note: This is an add-on/tape-on rear spoiler, not a replacement trunk component. Professional installation is recommended if you are not confident about surface preparation or alignment.

Before You Order

Three Checks That Prevent Fitment Problems

Confirm the Body Style

The vehicle must be a compatible sedan. Similar-looking Audi body styles use different trunk contours.

Confirm the Chassis

Use the chassis generation and model year together rather than relying only on the A4 or S4 badge.

Check the Existing Trunk

If the car already has a factory or aftermarket spoiler, send a clear rear photo before placing the order.

Frequently Asked Questions

Fitment, Material, and Installation

Is this a replacement spoiler?

No. It is an adhesive-mounted add-on spoiler installed over the compatible trunk lid. It does not replace the trunk panel.

Is it real carbon fiber?

Yes. The product is described as gloss wet carbon fiber, providing visible woven texture and a deep reflective finish.

Does installation require drilling?

No drilling is required. The spoiler uses an adhesive-mounted installation method, but correct cleaning, positioning, and bonding time are important.

Will it fit an Audi A4 Avant, Allroad, or wagon?

No. The listed fitments are for compatible sedan body styles only.

Will it fit an S4 B8 or B8.5?

The current fitment data lists B8 and B8.5 for the Audi A4 only. For North American vehicles, S4 compatibility begins with the 2018 B9 model year. Contact customer service with a rear vehicle photo before ordering an unlisted configuration.

Can I install it over an existing spoiler?

Fitment over an existing factory or aftermarket spoiler is not assumed. Send a clear rear photo for confirmation before ordering.

How should I care for the finish?

Use a pH-neutral automotive wash and a soft microfiber towel. Avoid aggressive polishing around the edges and inspect the adhesive bond periodically.
