CMST Porsche 911 (991) Carbon Fibre Body Kit
The CMST carbon-fibre kit for the Porsche 911 (991 generation) is a near-complete exterior conversion — a four-piece front bumper with carbon lip and intake vents, a matching four-piece rear bumper, carbon side-skirt lower lips, a lightweight carbon bonnet and a three-piece carbon rear wing. CMST developed the package to rework almost every panel except the roof, giving the 991 a far more aggressive face and tail than standard. The front and rear bumpers are offered in a carbon-and-FRP construction, while the lip, vents, skirts, bonnet and wing are dry carbon fibre.

Reworking an icon without touching the roof
The 911 is one of the most recognisable shapes in motoring, which makes a full body kit a bold proposition. CMST's approach is comprehensive: aside from the roof, almost every exterior panel is addressed, so the converted car looks markedly different from a standard 991 while keeping the silhouette unmistakably 911. The front and rear bumpers are the centrepieces, each a four-piece assembly that integrates a carbon lip and a pair of carbon air intakes. Browse the platform's options in the CMST body kit for Porsche collection.
Front bumper: carbon lip and intake vents
The front bumper is the change that most alters the 991's face. Built as a four-piece set, it carries a carbon front lip along its lower edge and a pair of large carbon air intakes whose surrounds are finished in exposed weave. The enlarged side intakes dominate the new front and give the car a much wider, more purposeful look, while the lip sharpens the leading edge and helps manage airflow under the nose. Standalone front options are in the CMST front lip for Porsche collection, and bumper sets in the CMST bumper for Porsche collection.
Rear bumper: matching openings and carbon vents
The rear bumper mirrors the front with its own four-piece construction, a carbon rear lip and a pair of large openings flanked by carbon vents. Matching the front and rear treatments is what makes the conversion read as a coherent whole rather than a collection of parts — the same intake language front and back ties the car together. The rear lip deepens the lower bumper and frames the exhaust and diffuser area. Rear options sit alongside the front in the CMST bumper for Porsche collection.
Side-skirt lower lips and carbon bonnet
Carbon side-skirt lower lips run along the sills to extend the front and rear visually and drop the apparent ride height. Above them, a lightweight carbon bonnet replaces the factory panel — a change that removes weight from high over the front axle, where it most benefits the car's balance, and adds a hard carbon accent to the nose. On a rear-engined 911, trimming mass at the very front is a worthwhile, if modest, dynamic gain. Skirt options are in the CMST side skirts for Porsche collection and bonnets in the CMST hood for Porsche collection.
Three-piece carbon rear wing
The kit is topped by a three-piece carbon rear wing — a ducktail-style element that lifts the completeness and visual aggression of the conversion. A wing of this type adds a measure of high-speed rear stability and gives the tail a finished, motorsport-inspired profile. Because it is supplied in carbon, it stays light and shows the weave as part of the design. Wing and spoiler options are in the CMST wing for Porsche and CMST spoiler for Porsche collections.
Carbon and FRP: why the kit uses both
This package deliberately combines carbon fibre and FRP, and each material earns its place.
| Material | Where it's used and why |
|---|---|
| Dry carbon fibre | Lip, vents, side-skirt lips, bonnet and wing — lightest weight and exposed woven finish on the visible accent pieces |
| FRP (fibreglass) | Used within the larger bumper structures, where it offers strength and a cost-effective base for big panels |
| Carbon bonnet | Removes weight high over the front axle to benefit balance on a rear-engined car |
| Exposed weave | Contrasts with body colour and marks the car out as a considered build |
For owners who want their 991 to look dramatically different while keeping real carbon where it counts, this combination is sensible. Compare the wider range in the All Carbon Fibre Body Kit collection or browse the brand on the CMST page.
What a styling kit changes — and what it doesn't
It is worth being clear about scope. This kit reshapes the 911's bodywork and adds carbon detailing and aero elements; the carbon bonnet and wing bring genuine, if modest, weight and stability benefits. What it does not do is alter the engine, drivetrain or factory power output — those are unaffected by exterior carbon. For most owners the appeal is exactly that: a 991 that looks far more aggressive and individual while retaining the car's mechanical character and everyday usability. The honest summary is a comprehensive appearance and aero upgrade rather than a performance overhaul.
Fitment and finish in Australia
This is a large, multi-piece kit with full front and rear bumpers, so it is best installed by a workshop experienced with carbon and FRP panels. Plan for careful alignment of the bumpers, accurate bonnet fitment and clean bonding of the lips, vents and skirts. Exposed carbon should be protected with a UV-stable clear-coat and, where practical, kept out of prolonged harsh Australian sun to preserve the weave. Confirm any bonnet, bumper or aero changes meet your state's vehicle-standards requirements before road use. To plan a 911 build, start with the CMST body kit for Porsche collection.
Frequently asked questions
Which Porsche 911 does the CMST kit fit?
It is developed for the 991-generation Porsche 911. Because the 991 spans several variants and a facelift, confirm your exact model year and body style with our team before ordering so the bumpers and panels match your car.
Is the whole kit carbon fibre?
The lip, intake vents, side-skirt lips, bonnet and rear wing are dry carbon fibre with an exposed weave. The larger front and rear bumper structures use a carbon-and-FRP construction, which keeps the big panels strong and cost-effective.
Does the carbon bonnet improve performance?
It is lighter than the factory bonnet and removes weight from high over the front axle, which benefits balance and turn-in on a rear-engined 911. Its main benefits are weight reduction and a sharper, more aggressive front.
How different does the car look afterwards?
Significantly. CMST reworks almost every panel except the roof, so the front face, rear and profile all change. The enlarged front and rear intakes and the carbon wing give the 991 a much wider, more motorsport-inspired appearance.
Can I fit the bonnet or wing on their own?
Yes. The bonnet, wing, front lip, vents and side-skirt lips are available individually, so you can stage the build — many owners start with the bonnet and front lip, then add the bumpers and wing later.
Will the front lip clear Australian driveways?
The carbon front lip extends the lower bumper and sits lower than standard, so take normal care over steep driveways and speed bumps as you would with any front lip. Our team can advise on the practicalities for daily driving.
