    Front splitters are very effective at producing front end downforce without increasing drag significantly. They do this by creating a large pressure delta between the top and bottom surfaces. We then incrementally improved the front splitter by adding design tweaks to the underside of the splitter to improve flow with our carbon splitter diffusers. All of this adds up to a front splitter kit for the 991.1 GT3RS that creates a large amount of additional front end downforce.

    The splitter is produced from a carbon thermoplastic, which is the same material used in high forms of Motorsports. The material is not brittle, so no more issues with cracking like carbon fiber and ABS. It will not grab and bend under the car like aluminum units either. It is a great splitter material.

    Bracketry was designed off scan data and precision cut and bent to ensure repeatability. The carbon diffusers were developed in CFD to promote flow and improve downforce generation. The splitter was designed to balance out large rear wings, more specifically our V1x for the chassis.

    Front splitters, when designed properly, greatly increase front-end grip and this is the case with our splitter and the 991.1 GT3RS.  Utilizing state-of-the-art analysis software, we were able to extract more performance from the front splitter, air dam, and diffuser combo through an iterative design process. We were also able to properly size the front splitter and dive planes to counteract the rear wing and factory diffuser creating a safe and effective aero balance.

    The front splitter is part of our Ventus 2 and 3 Kit for the Porsche 991.1 GT3RS. The Ventus 2 and 3 kit boosts downforce significantly from the factory vehicle. The goal was to create a package that dramatically improved the aerodynamic performance of a factory 991.1 Porsche GT3RS in a safe and balanced package for the typical track/HPDE enthusiast. Another goal was to retain street-ability from the aerodynamic components; with reasonable front splitter stick-out and rear wing widths.
