SFORZA Carbon Fibre Front Fender Louver Covers 

Enhance the aggressive motorsport styling of your Porsche 991.2 GT3 RS or GT2 RS with the SFORZA Carbon Fibre Front Fender Louver Covers.

Fits:

  • Porsche 991.2 GT3 RS 4.0L (520 Bhp) 2017-19
  • Porsche 991.2 GT2 RS 3.8L PDK (700 bhp) 2018-19

Designed specifically to cover the original plastic front fender louvers, these premium carbon fibre components introduce a high-quality exposed carbon finish to one of the most distinctive aerodynamic features of the RS models. The result is a sharper, more sophisticated appearance that complements other factory or aftermarket carbon fibre exterior components.

Pre-Preg Autoclave Carbon Fibre Construction

The SFORZA front fender louver covers are manufactured from pre-preg carbon fibre using an autoclave moulding and curing process. This premium manufacturing technique delivers excellent surface quality, accurate construction and the crisp detailing expected from a high-end carbon fibre component.

Each cover is completed with a glossy clear coat, highlighting the carbon weave while providing a deep, premium finish.

Carbon Fibre Upgrade for the 991.2 GT3 RS & GT2 RS

The distinctive front wing louvers are an integral part of the purposeful appearance of the Porsche 991.2 GT3 RS and GT2 RS. The SFORZA covers retain the original design while replacing the visual appearance of the standard plastic surface with exposed carbon fibre.

This makes them an ideal upgrade for owners looking to create a more cohesive carbon fibre exterior package, particularly on cars already equipped with carbon mirrors, bonnet components, rear aero parts or other carbon fibre detailing.

Installation

The SFORZA carbon fibre louver covers are designed to install directly over the original plastic fender louvers rather than replacing them.

Installation requires suitable automotive adhesive, which is not supplied with the product. Correct positioning and adhesive application are important to achieving a secure, clean and professional result.

Due to the installation method, fitting should be carried out by a knowledgeable professional with previous experience installing bonded automotive components and working with appropriate adhesives.

Why Choose SFORZA Carbon Fibre Fender Louver Covers?

For Porsche owners looking for carbon fibre front fender louver covers for the 991.2 GT3 RS or GT2 RS, these SFORZA components provide a premium visual upgrade while retaining the underlying factory components.

Their pre-preg autoclave carbon fibre construction and gloss clear coat finish provide the high-quality appearance expected on Porsche's most focused RS models.

Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.
