No more wondering what a “Cayman GT3” would look like!
Featuring a daring pipe frame rear end
In an attempt to go beyond Porsche’s own ready to race 911 GT3R and assorted cup cars, M’s Machine Works created this 987 Cayman.
While leaving the cabin intact, the rear end has been stripped away and replaced with a pipe frame. The car gets a heart transplant, receiving the 3.8L (M97/78) unit from a 997 cup car. This produces 450ps, and is paired with a Hewland NLT transmission. Also worthy of note is a Motec M800, allowing the change to paddle shifter operation.
After changing the rear suspension from MacPherson struts to a one-off multilink setup, the quest for ever faster times prompted the huge change to an inboard system. The inspiration for this work was apparently the 911 GT1 that ran at Le Mans. The dampers are from Element Sports, with HAL springs joining the party.
The cockpit, dominated by a welded rollcage is an extremely spartan affair. Gone is the gear lever, a result of the switch to paddle shifters. Furthermore, the replacement of the rear section with a pipe frame provides weight savings of 100kg.
No holds are barred outside either. Porsche 997 headlights replace the originals, and a custom body kit replaces all exterior panels excluding the hood. The rear fenders have increased markedly in size, bringing the cars width to 1950mm. A street version of this ferocious aero kit that makes even the GT3R quake in its boots is already ready to go on sale.
Impressively, the wheels get a set of centerlock hubs. These are M’s Machine Works’ own design, and hold in place Volk Racing centerlock racing wheels designed for use in the Super GT300 series. The tires are Advan A050s in extra wide 295/35 size.
Whilst the rear pipe frame stretches the wheelbase 85mm, this apparently still doesn’t reach the ideal length for a midship car. “To be so fast with a short wheelbase RR drivetrain, the 911 is a truly special machine,” opines M’s Machine Works’ Mizumoto-san.
With constant improvements since the project began five years ago, this monstrous tuned Cayman made its time of 58.070 at Tsukuba look easy – and this whilst still in the set-up stage. The goal for the time being is to get under 57 seconds, but there are no plans to make this a Time Attack special. M’s Machine Works say they are aiming to make this a real tuned car that drivers can enjoy driving at the track – and look cool doing it.
