CMST Porsche Taycan Widebody Carbon Fibre Aero Kit
The CMST widebody aero kit for the Porsche Taycan wraps a purpose-built carbon fibre and fibreglass reinforced set of body pieces around one of the most aerodynamically refined electric sports cars ever produced. The kit includes a carbon fibre front lip, two-piece side skirt lips, rear lip with corner trim, eight-piece widebody wheel arch extensions, and a carbon fibre rear wing — available in full carbon or a hybrid version that substitutes FRP arches for a lower entry cost. Every panel is engineered to bolt onto standard Taycan body mounting points without modification to the chassis structure.

Why a Widebody Kit on an Electric Porsche
The Taycan's production body is a triumph of aerodynamic efficiency. Porsche's engineers spent thousands of hours in the wind tunnel achieving a drag coefficient of just 0.22 Cd on the standard Taycan sedan. Yet the factory arches sit relatively flush against the body, leaving the wheel-to-arch relationship looking conservative compared to the Taycan's electric-performance ambitions. A widebody conversion solves this by visually and physically widening the car's stance to accommodate wider tracks, larger-section tyres, or simply a profile that reads as deliberately extreme.
Carbon fibre is the rational material choice here. The Taycan's body panels are already high-strength steel and aluminium alloy, and adding mass through heavy fibreglass pieces works against the efficiency the electric drivetrain promises. A set of dry carbon fibre wheel arches contributes a fraction of the weight that equivalent fibreglass panels would, keeping the car's total mass penalty minimal. Where budget is a consideration, the FRP arch option allows fitment and later replacement with carbon if priorities shift.
Kit Components in Detail
Front Lip
The carbon fibre front lip fits directly beneath the Taycan's factory front bumper, extending forward and downward to sharpen the car's approach angle. The design incorporates a mild splitter profile that works with the factory ducting in the lower fascia. Because the Taycan's nose already sits very low — Porsche specifies active air suspension that can raise the nose for driveways — the aftermarket lip requires particular attention to ground clearance on the Australian urban network. Most owners set the air suspension to its raised mode for slow-speed kerb negotiations and lower it at speed, which pairs well with the aerodynamic intent of the lip.
Side Skirt Lips
The two-piece side skirt lips mount beneath the Taycan's existing sill extensions. The two-piece construction is deliberate: it makes fitment around the battery pack cooling ports easier and reduces the risk of a single panel flexing along its full length. The wave-form profile adds visual width to the lower body while the carbon weave is left exposed for a texture contrast against the painted bodywork above.
Rear Lip and Corner Trim
The rear lip mounts across the base of the rear bumper and incorporates separate corner pieces that wrap around each side. This corner-trim approach improves the visual continuity of the kit from sill to rear fascia. The rear lip also provides a natural mounting partner for the rear wing, creating a coherent visual baseline from which the wing element rises.
Eight-Piece Widebody Wheel Arches
Eight individual arch extensions — two at each corner — are the defining element of this build. The split construction allows each piece to follow the Taycan's complex compound curvature individually, rather than demanding a single stamped piece to conform to multiple radii. In carbon fibre, the four-piece-per-corner breakdown keeps each panel small enough to be laid up without voids. In the FRP version, the split is still used for fitment accuracy, though the material is primer-ready for body colour matching rather than left exposed.
The arch extensions add genuine width to the Taycan's stance, accommodating wheels up to 21 or 22 inches running wider-section tyres. Porsche's factory 21-inch packages run up to 265-section rear tyres on the Turbo S; the widebody arches create clearance for up to approximately 285-section rubber depending on offset. Any tyre-and-wheel combination should be verified against the extended body before purchase using the vehicle's specific suspension geometry.
Rear Wing
The carbon fibre rear wing mounts at the trailing edge of the Taycan's bootlid. The design uses an open-lattice mounting structure — described as perforated or hollow in the source material — which reduces the visual mass of the mounting pillars while maintaining structural rigidity. At highway speeds, a fixed wing of this profile generates meaningful downforce at the rear axle, complementing the car's standard rear active aerofoil. Buyers should note that the CMST wing adds fixed downforce regardless of speed; it does not replicate the factory wing's variable-angle behaviour, so overall aerodynamic balance differs from stock at low speeds.
Carbon Fibre vs FRP: Which Should You Choose
The CMST Taycan widebody kit is offered in two primary material configurations. Understanding the difference is straightforward:
| Feature | Full Carbon Fibre Kit | Hybrid Kit (Carbon + FRP Arches) |
|---|---|---|
| Wheel arches material | Dry carbon (exposed twill weave) | FRP (fibreglass, primer finish) |
| Front lip / skirts / rear lip / wing | Carbon fibre | Carbon fibre |
| Paint matching | Carbon exposed; no paint required | Arches require body colour painting |
| Weight | Lower (carbon arches) | Higher (FRP arches) |
| Suited to | Carbon-contrast aesthetic, concours builds | Full body-colour widebody builds |
For a Taycan in a darker body colour — Volcanic Grey, Night Blue Metallic, or similar — carbon-exposed arches read as a deliberate contrast material and need no additional finish work. For owners who want a full painted widebody look, the FRP arches allow colour-matched paint before fitment. Either way, the carbon fibre front lip, side skirt lips, rear lip, and wing remain in exposed carbon weave.
Fitment and Installation Considerations
Installing widebody arches on a Taycan involves several steps that differ from simpler lip or spoiler fitment. The process generally requires removing the factory wheel arch liners, drilling or bonding the extension pieces to the outer body, and reinstalling the liners behind the new arches. Many installers also apply a thin bead of automotive-grade body adhesive along the inner edge of the arches to eliminate panel gaps, followed by machine-polishing the seam where the arch meets the original paint.
The Taycan's active air suspension introduces a specific consideration: the ride height range must be checked against the extended arch position to ensure the front and rear arches do not contact the tyres at any suspension travel point. Porsche's air suspension on the Taycan operates across a range of approximately 90 mm from its lowest to its highest position; arch fitment should be confirmed against the lowest (track) ride height setting.
Australian climate conditions — particularly UV exposure in Queensland and Western Australia — mean all carbon panels should be coated with a quality UV-stable ceramic or PPF immediately after fitment to prevent the resin yellowing over time. Exposed carbon without UV protection will amber noticeably within two to three years in high-UV environments.

Building a Complete Taycan — Wheel Pairing
A widebody conversion without a corresponding wheel upgrade is a common mistake. The Taycan's factory 20- and 21-inch wheels are designed to the original track width, and the extended arches will appear to swallow them without appropriate offset adjustments or a larger wheel. Most builds pair the CMST widebody kit with 21 or 22-inch forged wheels running roughly 10–10.5-inch-wide fronts and 11–11.5-inch-wide rears. The goal is to fill the arch visually — approximately 5–10 mm of space between the tyre sidewall and the inner arch edge is the typical target. CMST forged wheels for Porsche are engineered with the widebody offset clearances in mind and are a natural companion to this kit.
Frequently Asked Questions
Does the CMST Taycan widebody kit require cutting the factory body panels?
No cutting of the Taycan's steel or aluminium body panels is required. The eight-piece arch extensions mount over the factory body using a combination of bolt-on hardware and adhesive bonding to the wheel arch lip. The process is reversible in that the car can be returned to standard body panels, though paint repair to the mounting points would be necessary.
Will the widebody arches void the Taycan's factory warranty in Australia?
Australian Consumer Law protects warranty rights. An aftermarket body kit does not automatically void a factory warranty. However, Porsche Australia dealers may decline warranty claims on components that they believe were directly damaged by the modification. Structural electrical components, battery pack, or air suspension components are unlikely to be affected by an external body kit, but owners should document the fitment professionally and retain all records.
What wheel size should I run with the CMST Taycan widebody arches?
Most builds use 21-inch or 22-inch forged wheels with approximately 285mm-section rear tyres and 265mm-section fronts. Offset requirements vary between the front and rear axles, and the specific offset must be calculated against the suspension geometry of your particular Taycan variant (Taycan 4S, Turbo, Turbo S, etc.). A wheel fitment specialist who has handled Taycan widebody builds should confirm measurements before ordering wheels.
Can the FRP wheel arches be painted to match the factory body colour?
Yes. The FRP (fibreglass-reinforced plastic) arch option in the hybrid kit is supplied in a primer-ready finish, designed to accept automotive basecoat and clearcoat. A professional automotive painter with experience in Porsche colour matching can achieve a seamless colour match. Metallic Porsche colours such as Frozen Berry Metallic or Dolomite Silver Metallic require extra care in achieving panel-to-panel consistency, so provide the painter with the Porsche factory paint code from the vehicle's VIN sticker.
How long does the CMST Taycan widebody kit take to install?
A professional installation involving all eight arch pieces plus the front lip, side skirts, rear lip, corner trims, and rear wing typically takes two to three full working days. This allows time for dry-fitting, alignment, adhesive curing, and final polishing. Rushing the installation, particularly the arch fitment, risks panel alignment gaps that are difficult to correct without removal and restart.
Is the CMST rear wing compatible with the factory Taycan active rear spoiler?
No. The CMST fixed carbon fibre rear wing mounts in the same location as the factory active spoiler and replaces it. Owners who retain the active spoiler mechanism cannot simultaneously run the CMST fixed wing. If preserving the factory spoiler's variable-angle function is a priority, the rear lip and wing combination is not appropriate for that build direction.
