Gunther Werks GXR-EVO Is a Wild 993 RestomodGunther WerksEven among the seemingly endless pool of Porsche 911 restomods on offer these days, few of these reworked classics are truly quite as crazy as what comes out of Gunther Werks. The purveyors of the world's most extreme 993-generation Porsches continue to find ways to push the limits of Stuttgart's last air-cooled model, and this year's Monterey Car Week festivities serve as the perfect backdrop to reveal the brand's most extreme model yet. This is the Gunther Werks GXR-EVO: a limited-production monster aimed at bringing track-focused thinking to public tarmac.Like every Gunther Werks model, the process begins with a 993-generation donor vehicle. There's not much left of the original car that you can spot however, as the GXR-EVO gets every goodie the shop could throw at it. The brand's carbon-fiber body has been revised with a greater focus on aero elements, resulting in new splitters front and rear, dive planes, and a truly kick-ass-looking high-downforce wing so big, it required the removal of the rear window and the installation of a stability element.The weight savings measures were also taken to the extreme, with Gunther Werks finding an additional 210 pounds to remove when compared to the company's usual Coupe models. All told, the GXR-EVO tips the scales at just 2386 pounds dry.Gunther WerksUnder the rear decklid of the car sits a Rothsport-built 4.0-liter flat-six engine, which has been fitted with upgrades like a slide-valve throttle-body setup and intake inlets mounted in the rear quarter windows. Output is expected to sit at 455 horsepower, which is plenty in a car this light. You'll certainly get used to hearing the thing wail, however, as the GXR-EVO rocks a straight up straight pipe exhaust. (Neighbors beware.) A highly modified G50 six-speed manual gearbox out of a 993 sits mated to the engine.AdvertisementAdvertisementOther performance oriented highlights include a double wishbone front suspension, RZ three-way adjustable remote-reservoir dampers, a Brembo Pista brake setup front and rear, a built-in pneumatic air-jack system, and lightweight magnesium center-lock wheels. Some motorsport-specific items find their way inside as well, including Motec displays, a helmet-cooling system, OMP electronic fire-suppression, Racetech carbon-Kevlar racing seat, six-point harnesses, and an eight-point roll cage. The GXR-EVO also adopts race-grade ABS and an electronic rearview mirror to replace the view blocked by its shark fin.Gunther WerksIf the performance alone wasn't enough to tempt a call to your financial adviser (or considering the likely audience for this car, your family office), we should also add that every GXR-EVO will include a bespoke racing simulator as part of your purchase. Crafted from aluminum and carbon fiber and featuring a wheel inspired by the actual car, Gunther Werks says this is the perfect tool for getting ready for a track day in your new ride. Software has reportedly even been developed to accurately represent the car's dynamics within the sim.We at Road & Track would love to get a crack at the car and see what it's like for ourselves, but given how few of these GXR-EVOs are slated for production—Gunther Werks will only build 15 copies—that seems like a bit of a straight pipe dream.You Might Also LikeIf You Can Only Own One Car, Make It One of TheseThese Are the Most Popular Cars by State
