2023 Porsche 911 GT3 RS with Manthey Performance Kit

The Manthey Performance Kit: A Powerful Upgrade for the Type-992 911 GT3

Manthey-Racing has recently unveiled a performance kit specifically designed for Type-992 911 GT3 owners in the United States. Marking a first for the company, this upgrade kit is set to take the already formidable track performance of the GT3 to new heights. The enhancements touch on various aspects of the car, including aerodynamics, chassis setup, braking, and unsprung mass reduction, aiming to deliver a greater level of driving confidence across all skill levels.

Performance Improvements

The Manthey Performance Kit results in remarkable improvements. In fact, a GT3 equipped with this upgrade kit managed to complete a lap at the Nürburgring Nordschleife in a swift 6:55.737 minutes, outpacing the standard 911 GT3 by a considerable 4.19 seconds. Importantly, despite the bolstered performance, road registration and the new vehicle warranty remain intact for the equipped models, making the Manthey upgrade a relatively risk-free proposition for owners.

Experience Before Purchase

From June 2023, Porsche Experience Centers in Atlanta and Los Angeles will give driving enthusiasts the chance to test drive a Manthey-equipped 911 GT3. This feature provides an excellent opportunity for potential buyers to compare the experience of a 911 GT3 with and without the Manthey Performance Kit, offering a comprehensive understanding of the changes the kit brings about. Participants can opt for an extended, four-hour program at the PEC Los Angeles for a deeper dive into the enhanced driving experience.

Aerodynamic Alterations

Aesthetically, the aerodynamic modifications implemented by the kit distinguish the upgraded GT3. The enhancements include larger spoiler lips, side flaps at the car's front, modified air guide elements on the underbody, and an extended, carbon fiber reinforced plastic (CFRP) rear diffuser. The result is increased downforce on the front axle, contributing to better control and stability at high speeds. The alterations at the rear, including a wider swan-neck-supported wing with a Gurney flap, enlarged end plates, and aerodiscs on the rear wheels made of CFRP, further enhance the aerodynamic efficiency.

Suspension, Braking, and Unsprung Mass Reduction

The Manthey kit comes with a specially developed four-way coilover suspension, an impressive collaboration between Porsche and Manthey. It allows for four-position adjustments without tools, moderately increasing spring rates by 10 percent at the front axle and seven percent at the rear. This innovation improves handling without sacrificing daily usability. Furthermore, the kit includes braided steel brake lines and offers optional lightweight forged wheels that reduce unsprung mass by approximately 16 lbs.

The Manthey Performance Kit is now available for purchase through Manthey-certified Porsche Centers. The starting MSRP for the kit stands at $57,300. Those interested in additional lightweight forged wheels will need to consider an extra cost of $15,500, exclusive of the labor costs for installation. The upgrade offers a balance of performance, aesthetics, and usability that GT3 owners might find quite appealing.
