Brit buff mag Autocar says that Porsche is readying a lightweight version of the new Cayman, with plans to create a single-make racing series for it as it already does with the 911. The Porsche Cayman Clubsport, as it'll reportedly be called, will weigh 220 pounds (100 kg) less than the standard-issue car. The weight savings will come via a stripped interior, lighter bodywork and wheels, and a "simplified" lighting system. Engine/transmission changes aren't expected to be part of the go-fast recipe, but the 314-horsepower six that's fitted to new Cayman S ought to deliver more than ample punch in the lighter Clubsport. Autocar says that a price premium of £4K is expected over the regular Cayman S, and that the car should arrive in the UK market in October. Porsche finally gives the Cayman S an engine that makes it a legit alternative consideration to the 911, and now it seems ready to turn up the heat even further with a lightweight version. Man, where do we sign up?
