Manthey Racing

MR tuning by JZM

Manthey are so good at making Porsche go quicker round tracks that when Porsche bought 51% in to Manthey-Racing they kept the name above the door. We’ve been friends with Olaf Manthey for over 30 years and install Manthey-Racing parts today as we have done since becoming their UK’s first official agent – methodically and meticulously with Germanic precision. TÜV (Technischer Überwachungsverein) approved and ready for Manthey-Racing track day invitations.

On 14 June 2021 Lars Kern topped the list of fastest production cars on the Nürburgring Nordschleife with a lap record of 6:38.835 in a Porsche 911 GT2 RS (991.2)

Porsche has to build a car for anybody. We build a car for track day fanatics. We don’t have to serve the 100%, we serve a percentage of freaks.” Michael Grassl, Manthey Racing.
