2026 Porsche 911 GT3 Manthey: Best of Both WorldsPorsche (Porsche)Every time you think there can't possibly be room for yet another variant of 911, Porsche says, "Hold mein Bier." Porsche long answered owners' requests for a more track-focused GT3 by directing them to the GT3 RS, but here's an alternative answer. Keep your GT3—just fit it with the kit developed by Manthey Racing.This one's a bit different. Instead of being plucked from dealer inventory, it's an aftermarket kit—one that costs $70,657 before tax and installation. It offers no more power and removes no weight, which makes it something of a hard sell, you'd imagine. Put it this way: You've got to buy into the idea of this kit and care deeply about Manthey and its expertise.Porsche (Porsche)At the core of it, fitting this kit removes about 5.5 seconds from the GT3's Nürburgring lap time. But that's not why you should care about it. Instead, point your attention to something Car and Driver editor-in-chief Tony Quiroga wrote about the GT3 last year: "The softest damper setting is Sport, and it's stiff enough to send your coffee shooting out of your Yeti and onto your cords."AdvertisementAdvertisementFit the hardcore Manthey kit, and that won't happen. Because it rides better and is more supple and fluent than the standard car. And yes, still 5.5 seconds faster around Germany's most famous track. Weird one, huh?What Makes Manthey So Compelling?Manthey was a super-successful race outfit using 911s to win at Le Mans and the Nürburgring 24 Hours. It won so heavily that in 2013 Porsche bought 51 percent of the business. Manthey carried on racing, and Porsche carried on doing road cars.Porsche (Porsche)In 2017, the GT2 RS held the Nürburgring road-car lap record, at 6:47.25. But then along came Lamborghini with the Aventador SVJ, and then AMG with the GT Black Series, lowering the record to under 6:43.62. Porsche wanted to fight back, but with no new GT2 in the pipeline, what could it do?What Porsche did was call its racing partner and ask for help. However, that help had to be very specific, because Porsche wasn't about to put the GT2 back through the frustrating process of homologation. Thus, the resulting car couldn't have less—or more—aero drag, be lighter or lowered, use more fuel, or feature any engine mods. It had to fit the exact same boxes. And it had to be fully warrantied by Porsche, with components put through the same durability tests.AdvertisementAdvertisementAnd yet, targeting only aerodynamics and suspension, Manthey managed to improve the GT2's lap time by four seconds and reclaim the record. Ever since, Porsche has allowed Manthey to take an RS and make it faster. Equipped with Manthey's package, the 992.1 GT3 RS's lap time fell by four seconds, and the Cayman GT4 RS's dropped by more than six seconds.The Latest Bag of TricksSo what fairy dust is Manthey sprinkling on these cars? Let's have a look at this new GT3. Outside, you'll notice the rear wheel spats (which help smooth airflow leaving the car) and the bigger rear-wing end plates (designed to angle the air inward so it stays attached over the lower ducktail wing element). But it's what you don't see that contributes most to a total downforce figure of nearly 1200 pounds at 177 mph.The front splitter protrudes 0.5 inch farther and curves upward to channel more air underneath. Once there, it's grabbed by a series of new, deeper turning vanes and directional elements, some up to 60 inches long, that guide the air around. Downforce at the front axle is up 30 percent, and the larger diffuser in the back is borrowed from Manthey's GT3 RS.Porsche (Porsche)Then there's the suspension. Manthey installs new springs all around—20 percent stiffer at the front and 7 percent softer at the back. The adaptive dampers are replaced with manually adjustable four-way passive dampers. If you want to change the settings, prepare to lie on your back in a pit lane.AdvertisementAdvertisementAfter this, it's minor stuff: braided-steel brake lines, illuminated carbon doorsills, a badge on the console, LED puddle lights (even Manthey isn't immune to a bit of frivolous jewelery). But there's no need to stop there. The car we drove had extra Manthey options, including tow hooks, upgraded brake pads, a carbon-fiber kit, and fancy lightweight aluminum wheels that are only three pounds heavier in total than Porsche's ferociously expensive magnesium rollers. Those extras are not inexpensive, though: All told, that added another $33,000.Porsche (Porsche)Driving the Manthey GT3Fit this kit to your GT3, and you'd better have the driving skills to match. And think very hard before deciding to leave those carbon wheel spats installed if you're taking on a Starbucks drive-through, as scraping one of them will definitely deposit your latte in your lap.But as a car to drive through twisties or on a track, it is sublime. The engine and gearbox are directly carried over, but that's nothing to complain about. Sure, it makes "only" 502 horsepower, but we all know Porsche breeds healthy horses. The 4.0-liter flat-six is a zinger, howling to 9000 rpm, with a razor-sharp throttle and nearly instantaneous shifts from the PDK dual-clutch automatic gearbox. It ensures the whole car tingles with attitude and eagerness.Porsche (Porsche)Through high-speed corners, you can feel the additional downforce. It's not quite the heavy hand pressing down from on high that you get with the RS, but stability and composure are a step up from the regular GT3.AdvertisementAdvertisementAerodynamic tweaks are felt only part of the time on track, never on the road, whereas suspension compliance is noticed all the time. It's still very short on travel, but the amount of damping ability packed in here is remarkable. Where the standard car fidgets and feels hard, this one rounds off the edges of bumps better. It gives the car more on-road fluency and makes it feel more approachable, while it feels less snatchy on the track and does a better job of filtering information. This calmness, combined with wonderfully communicative steering, gives you the most important thing of all: confidence.Porsche (Porsche)There is still a bit of lateral bob and skip from those stiffer front springs across midcorner surface changes, but the trade-off is a nose that goes exactly where you point it with zero delay. It loves braking deep into apexes, then using those softer rear springs to flex and pull more grip from the rear tires on the way out.Overall, the impression is not that the Manthey-blessed GT3 is a more serious driver's car, but rather it's a more forgiving and flattering one. Most people want the full package, so other people can see what they've got. But if you'd rather keep your coffee in its cup, you can head to Manthey's parts catalog and order just the springs and dampers.Porsche (Porsche)➡️ Skip the lot.
