The CMST aero kit for the Audi A7 is a full exterior package — FRP front and rear bumpers, carbon-fibre front and rear lips, FRP side skirts and a carbon bonnet — with an optional SUS304 stainless valved exhaust. The A7's factory design is already widely admired for its long, clean fastback lines, so this kit is about adding a sporting edge rather than fixing anything: it sharpens the lower body and gives a car penned for elegance a more athletic, individual stance. It is aimed at A7 owners who want their car to stand apart from every other one on the road without losing the shape that made them buy it.

• Vehicle: Audi A7 Sportback
• Material: FRP front bumper, rear bumper and side skirts; carbon-fibre front lip, rear lip and bonnet
• Key pieces: Front bumper, front lip, rear bumper, rear lip, side skirts, bonnet
• Exhaust (optional): SUS304 stainless valved cat-back, lighter than factory
• Finish: FRP supplied in primer for paint; carbon in gloss-lacquered weave
• Stance: Lowered, sharpened lower body — factory fastback silhouette retained

The A7 is one of those cars that is hard to improve because Audi got the proportions so right the first time. The trick to modifying it well is to respect the fastback roofline and concentrate the changes low down, where a sportier edge reads as intent rather than interference. That is exactly what this kit does — here is the breakdown.

The front: bumper and carbon lip

The front pairs an FRP front bumper with a carbon-fibre front lip. The bumper reshapes the lower front with more pronounced intakes and a more aggressive profile, while the carbon lip beneath it defines the leading edge and lowers the visual height of the nose. On a car as long as the A7, lowering the front this way is what stops the nose looking tall and gives the whole side profile a more planted, forward-leaning stance. The carbon lip provides a dark contrast edge against the bumper, the first of several carbon accents that run front to back.

The sides and bonnet

FRP side skirts run along the sills, lowering the visual height through the middle of the car and connecting the front and rear visually — important on a car with as much length between the axles as the A7. Because they are FRP and painted to match, they read as an extension of the factory bodywork rather than an add-on.

The carbon bonnet is the kit's signature piece. Replacing the large steel A7 bonnet with carbon removes a meaningful amount of weight from the front of the car — and because the bonnet is one of the biggest single panels on the car, the saving is more significant here than on a smaller vehicle. Less weight over the front axle helps the A7 feel more agile through corners and under braking, a genuine handling benefit on top of the visual upgrade of an exposed-carbon bonnet.

The rear: bumper and carbon lip

At the back, an FRP rear bumper and a carbon-fibre rear lip sharpen the tail to match the front. The rear lip adds depth and a diffuser-style lower edge that balances the lowered front and gives the A7's wide rear a more purposeful base. Together with the front, the result is a car that sits lower and looks more athletic from every angle while keeping the elegant fastback roofline that defines it.

The optional valved exhaust

For owners who want the A7 to sound as sporting as it now looks, CMST offers a SUS304 stainless valved cat-back. SUS304 is a corrosion-resistant stainless grade that handles heat-cycling far better than mild steel, so the system stays clean and intact through years of use, and the construction is noticeably lighter than the factory exhaust. The valve is the key feature: it opens and closes to control how much exhaust gas takes the free-flowing path, varying the back-pressure and, with it, the volume and tone. Open it for a deeper, sportier note; close it for a quiet, refined cruise — useful on a car that doubles as a long-distance cruiser. For the construction details, see the CMST cat-back exhaust range.

Why this kit suits the A7

The material strategy fits the car. FRP is used for the front and rear bumpers and skirts — large, paint-matched panels that take road abuse and need to blend seamlessly with the body colour. Carbon is reserved for the lips and bonnet, where weight saving and an exposed finish add the most: the bonnet for its mass reduction over the front axle, the lips for their defined edges and dark contrast. It is a considered split rather than carbon-everywhere for the sake of it.

Above all, the kit is restrained in the right way. It leaves the A7's celebrated roofline and main bodysides alone and concentrates on the lower body, so the car gains a sporting edge without losing the elegance that defines it.

Fitment and finish

Fitting this kit involves swapping the front and rear bumpers, so it is a more involved job than a bolt-on lip — the factory bumpers come off, the FRP units go on reusing existing mounts and transferring sensors and trim, and the carbon lips then mount to them. The carbon bonnet replaces the steel original on the existing hinges and latch. Because the FRP pieces arrive in primer, paint and colour-matching are part of the project.

Two notes for daily use. The front lip sits lower than standard, so steep driveways and speed humps need a careful approach angle. And the carbon pieces should be sealed and maintained like paint — a UV-protective coating once or twice a year keeps the lacquer clear under strong Australian sun. Professional fitment is recommended for the bumper swaps and to get the panel gaps even.

The CMST Audi A7 aero kit is a full exterior package: FRP front and rear bumpers and side skirts, carbon-fibre front and rear lips, and a carbon bonnet, with an optional SUS304 valved cat-back exhaust. It sharpens the lower body while keeping the A7's fastback roofline, and the carbon bonnet trims weight from over the front axle.

Frequently asked questions

What does the CMST A7 kit include?

The full kit comprises an FRP front bumper, a carbon front lip, an FRP rear bumper, a carbon rear lip, FRP side skirts and a carbon bonnet. A SUS304 stainless valved cat-back exhaust is offered as an option. It is a complete exterior package focused on the lower body, not a widebody conversion.

Is the kit carbon fibre or FRP?

It is a mix. The front and rear bumpers and the side skirts are FRP (fibreglass-reinforced plastic), supplied in primer for paint. The front and rear lips and the bonnet are carbon fibre. FRP suits the large paint-matched panels; carbon is used where weight saving and an exposed finish matter most.

Does the carbon bonnet make a real difference?

Yes. The bonnet is one of the largest panels on the car, so replacing the steel original with carbon removes a meaningful amount of weight from over the front axle. That helps the A7 feel more agile through corners and under braking, on top of the look of an exposed-carbon bonnet.

How does the valved exhaust work?

The optional SUS304 stainless cat-back uses a valve that opens and closes to control how much gas takes the free-flowing path, varying the back-pressure and therefore the volume and tone. Open it for a deeper, sportier note; close it for a quiet cruise. SUS304 resists corrosion and heat-cycling better than mild steel, and the system is lighter than the factory exhaust.

Will the kit ruin the A7's elegant shape?

No — it is designed to avoid that. The changes are concentrated on the lower body and the kit leaves the fastback roofline and main bodysides alone, so the A7 gains a sporting, lowered stance while keeping the proportions that define it.

Do the FRP pieces come painted?

No. The FRP bumpers and skirts are supplied in primer and sprayed to match your car's colour during fitment. The carbon lips and bonnet arrive in a gloss-lacquered weave and are not painted over.
