• 2021 Porsche 718 Cayman GT4 MR by Manthey Racing

Manthey Racing just injected a lot of DNA into the Porsche 718 Cayman GT4

LISTEN 02:57

Manthey Racing has created a tuning program for the Porsche 718 Cayman GT4 that taps into the sports car’s racing genes. The contents of the kit address the body, suspension, and brakes of the 718 Cayman GT4. There are no engine upgrades, though that’s expected given the tuner’s history with past projects, including one for the 911 GT3 RS. Monthly Racing hasn’t announced a price for the 718 Cayman GT4 kit.

Manthey Racing is responsible for some of Porsche’s most successful racers, as well as the 911 GT2 RS MR, which blitzed the Nurburgring with a lap time of 6:40.3, earning the distinction as one point as the fastest road-legal sports cars to take a lap around the vaunted circuit. The tuner’s new package for the 718 Cayman GT4 follows a similar script, focusing on aerodynamic and suspension improvements to make the sports car more capable on a race track.

The aerodynamic modifications include a gurney flap and new wing mounting brackets. Manthey also fitted the 718 Cayman GT4 with an air deflector and a set of protective grilles for the air intakes. The latter is an important tool that could reduce potential damages to the intakes.

The tuned Cayman sits on a set of forged wheels from BBS. The wheels have a Y-spoke design and are gold-finished. Uprated brake pads and braided front and rear brake lines are also part of the package. On the suspension front, Manthey installed a new set of coilover springs, dropping the coupe’s ride height enough to sharpen the car’s handling on the track.

The Porsche 718 Cayman GT4 MR is still powered by a stock 4.0-liter naturally aspirated flat-six engine. The unit produces 414 horsepower and 309 pound-feet of torque.

A six-speed manual transmission sends all that power to the two rear wheels, and in full bloom, the Porsche can accelerate from 0 to 62 mph in just 4.2 seconds on its way to a top speed of 188 mph.

Manthey Racing has earned a reputation for building all-world track toys and club racers. The tuner uses its know-how in motorsports to create tuning packages for road-legal vehicles with the goal of turning these vehicles into track superstars. The new 718 Cayman GT4 MR is the newest offspring from Manthey Racing, and it looks every bit as quick around a track as Manthey Racing’s reputation suggests.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio
