Porsche GT3 Manthey kit costs £56k

The Porsche 911 GT3 has a familiar problem — if you already own one, the next step up gets very expensive very fast. A GT3 RS is harder to get, more extreme to live with, and not always the car you want if you still drive on normal roads. So Porsche and Manthey have pushed a different answer back into the spotlight: keep the GT3, add the kit, and chase a lot more circuit performance without touching the engine. Recent UK drives put the number at roughly £56,000 before fitting, which is the part that makes everyone stop scrolling. (evo.co.uk) ### What is the Manthey kit, exactly? Basically, it’s a factory-approved bundle of chassis, aero and braking parts developed by Manthey Racing with Porsche. The 992.2 GT3 package includes adjustable coilovers, lighter wheels, brake hardware, aero discs, a larger rear wing and a reworked front aero (evo.co.uk)als pitch it as a road-and-track package rather than a pure race conversion. (manthey-racing.com) ### Why is the price the whole story? Because £56,000 is not trim-money. It’s another serious chunk on top of a car that already sits deep into six figures. CAR says that figure excludes fitting, and evo uses the same headline number, which tells you this isn’t a cosmetic add-on or a mild options-pack upsell. It’s Porsche asking GT3 buyers whether they want to spend sports-car money for the last layer of track capability. (carmagazine.co.uk) ### So what do you get for that? You get lap time, mostly. The standard 4.0-liter naturally aspirated flat-six stays untouched, so the gains come from how the car uses its power, not how much it makes. Reviews point to much bigger downforce, more front-end bite and a chassis that feels calmer and more adjustable at the limit. Tha(carmagazine.co.uk)t work harder and cleaner through corners. (carmagazine.co.uk) ### How much faster is it on track? A lot, by road-car standards. Porsche and Manthey previously quoted a 6:52.981 Nürburgring Nordschleife lap for the 992.2 GT3 with the kit, and newer coverage says the package has now gone quicker again, down to 6:50.863. Either way, the point is clear — this is a real engineering gain, not bro(carmagazine.co.uk)big deal. (carthrottle.com) ### Is it basically a GT3 RS substitute? Sort of — but not completely. The kit pushes the regular GT3 closer to RS territory in focus and aero effect, which is why reviewers keep framing it that way. But the RS is still the more extreme factory car, with a different personality and a bigger aerodynamic ceiling. The Manthey GT(carthrottle.com) much further toward track days. (carmagazine.co.uk) ### What’s the catch on the road? Turns out the catch is the same as ever with serious track hardware — some civility goes missing. Reviews say the car remains usable, but the setup is firmer, noisier and more obviously optimized for smooth tarmac and committed driving. That doesn’t make it bad on the road. It just means the kit makes the GT3 more honest about what it wants to be. (carmagazine.co.uk) ### Why does this matter beyond one expensive option? Because Porsche keeps finding ways to stretch the 911 ladder without inventing a whole new model. The Manthey kit lets the company sell more performance, more exclusivity and more Nürburgring credibility to people who are already in the ecosystem. For buyers, the question is b(carmagazine.co.uk)r-edged car above it. (manthey-racing.com) ### Bottom line? This is a very Porsche kind of offer — hugely expensive, very specific, and probably brilliant if you are exactly the target customer. The news isn’t that Manthey made the GT3 better. It’s that Porsche can now charge real-money-supercar cash for making an already great car just a little closer to a race car.
