The 911 GT3 RS is a complete sports car, but this kit somehow builds on that quite nicely

LISTEN 02:14

Mansory and company, do take notes. This is how you improve on a presumably well-rounded recipe that offers staggering performance right off the factory gate WITHOUT messing up with its design. Let’s check out this 911 GT3 by Manthey Racing.

This is a racing kit first and foremost

Manthey Racing is the most successful Porsche racing team out there.

Porsche itself holds a 51-percent share in Manthey, so the two companies are basically family. And with eight titles in the Porsche Supercup, five overall victories at the 24h of Nurburgring and two in Le Mans, who’s better at tweaking the GT3 RS than the skilled guys over at Manthey Racing?

Other than the visual tricks highlighted in the video, there’s no word of powertrain upgrades, but come on, are they really needed? We believe not. The 911 GT3 RS already cranks out 520 horsepower from a banshee-screaming 4.0-liter flat-six that revs all the way up to 9000 rpm.

Best thing, though? You can pick your weapon of choice when it comes to transmission. Purists will love the availability of the six-speed manual (optional), while automatic fans are in for some serious treat from the seven-speed dual-clutch PDK.

Heck, Car and Driver tests showed the GT3 RS can blast from 0 to 60 mph in 2.9 seconds, scorching through the quarter mile in eleven seconds flat at 129 mph.

Throw in the fact that Porsche also focused on the GT3 RS’ streetable side, and one might ask: is there really a better sports car out there, for road AND track? For road, we think not. For track days, Manthey Racing’s recipe might even touch on perfection.

Tudor’s first encounter with cars took place when he was only a child. Back then, his father brought home a Trabant 601 Kombi and a few years later, a Wartburg 353. At that time, he was too young to know how they worked and way too young to drive them, but he could see one thing – each of them had a different ethos and their own unique personality. As time went on, he started seeing that in other cars as well, and his love for the automobile was born.  Read More
