The short answer: a full RSI c6 carbon kit for the Porsche 992 GT3 RS typically covers the front lip and canards, side skirt extensions, mirror caps, rear wing uprights and swan-neck covers, engine cover, and rear diffuser, all produced in forged carbon or prepreg autoclave carbon and made to order in Italy. Individual pieces can be bought separately, or combined into a complete kit for a consistent weave, finish, and fitment across the car.
Why the 992 GT3 RS Is a Carbon Fiber Platform to Begin With
The Porsche 992 GT3 RS already ships from the factory with an unusually aggressive aero package — a swan-neck rear wing, a full underbody, and active aero elements borrowed from motorsport thinking. That makes it one of the few road cars where adding carbon fiber is not purely cosmetic: every panel we build is designed to work with the car's existing airflow, not fight it.
For owners, that means a carbon kit on this chassis is judged differently than on a hot hatch. Fitment tolerances are tighter, the OEM parts it replaces are already lightweight, and the visual bar — bare weave next to Porsche's own exposed-carbon options — is high. This guide breaks down exactly what goes into a full kit and why each component is built the way it is.
What's Included in a Full Carbon Kit
A complete RSI c6 kit for the 992 GT3 RS is modular — every part is engineered to be sold and installed on its own, but the full set is designed to read as one cohesive package.
- Front lip & canards: a direct bolt-on lip extension with optional canards for added front downforce, matched to the factory bumper's lines.
- Side skirt extensions: widen the visual footprint of the car and channel air along the sills toward the rear diffuser.
- Mirror caps: a lightweight direct-fit replacement for the factory mirror housings, available in gloss or matte forged carbon.
- Rear wing uprights & swan-neck covers: carbon covers for the wing supports that echo the factory swan-neck design while dropping weight versus painted OEM units.
- Engine cover: a full forged carbon engine bay cover, visible through the rear glass, finished to show the natural marbled forged-carbon texture.
- Rear diffuser: a larger, more aggressive diffuser profile than the factory unit, built to integrate with the GT3 RS's underbody aero.
Every one of these is available individually through our Porsche 992 GT3 RS collection, or as part of a bundled kit on request.
Forged Carbon vs Prepreg: What We Use Where
Not every panel on a GT3 RS kit is built from the same material, and that's intentional. Forged carbon — chopped carbon fiber strands compressed under heat and pressure into a mold — is ideal for smaller, complex-shaped parts like mirror caps and canards, where its distinctive marbled texture and structural strength in multiple directions matter more than a uniform weave.
Larger, flatter panels such as the front lip and side skirts are typically produced with prepreg carbon cloth, laid up by hand and cured in an autoclave for a traditional 2x2 twill weave with a deep, glass-like finish. We never use fiberglass or chopped-strand composites as a substitute for either process — every part in a GT3 RS kit is real carbon fiber, cured under heat and pressure, not gelcoat over glass mat.
| Part | Typical Material | Finish Options |
|---|---|---|
| Front lip & canards | Prepreg carbon | Gloss / Matte |
| Mirror caps | Forged carbon | Gloss / Matte |
| Side skirts | Prepreg carbon | Gloss / Matte |
| Engine cover | Forged carbon | Gloss / Matte |
| Rear diffuser | Prepreg carbon | Gloss / Matte |
Gloss or Matte: Matching the Factory Aesthetic
Porsche offers its own exposed-carbon options on the GT3 RS, usually in a satin or matte finish. Our kits are available in both gloss and matte, so owners can either match the factory carbon roof and mirror package or intentionally contrast it — a gloss front lip against a matte factory roof is a common combination our customers request. Whichever finish is chosen, we recommend keeping it consistent across all visible carbon parts on the car for a coherent result.
Fitment & Installation
Every part is molded from the 992 GT3 RS's factory panels, so fitment mirrors OEM tolerances rather than the looser gaps typical of universal aftermarket kits. Most components — mirror caps, front lip, engine cover — are direct bolt-on or adhesive-fit replacements installable with basic hand tools. Side skirts and the rear diffuser are more involved and are best fitted by a shop familiar with removing the factory underbody and rear bumper assembly, given the GT3 RS's active aero components underneath.
Because every kit is made to order in Italy, we build to the exact specification requested rather than holding pre-painted stock — this keeps weave orientation and finish consistent across a full kit, at the cost of a longer lead time than an off-the-shelf part. Owners planning a full kit should factor that lead time into any track-season or show deadline.

FAQ
Is the RSI c6 kit a direct bolt-on for the 992 GT3 RS?
Most components — mirror caps, front lip, engine cover — are direct-fit replacements for the factory parts. The side skirts and diffuser require more involved fitting due to the car's underbody aero, and we recommend a shop experienced with the GT3 RS for those pieces.
Will a carbon kit affect the GT3 RS's factory aero balance?
Our panels are designed to follow the factory bodylines rather than override them, so front-to-rear balance is preserved. Adding canards or a more aggressive diffuser lip does shift aero slightly toward more front or rear downforce — we can advise based on how the car is used.
What's the difference between forged and prepreg carbon on this kit?
Forged carbon uses chopped strands pressed in a mold, giving a marbled texture and better strength for complex shapes like mirror caps. Prepreg carbon uses woven cloth cured in an autoclave, giving the classic twill weave look on flatter panels like the front lip and diffuser.
Can I order just the mirror caps or engine cover instead of the full kit?
Yes — every part is sold individually. The full kit is simply our recommended combination for a consistent look; there's no requirement to buy the whole set at once.
How long does a made-to-order kit take?
Because each part is produced to order in our Italian workshop rather than pulled from painted stock, lead times run longer than a generic aftermarket part. We recommend ordering well ahead of any track day or show deadline — get in touch for a current estimate.
