Porsche's official stance is they will not release a lightweight racing version of their new Cayman coupe. The Cayman S will be followed by a base Cayman with less power and equipment. The statement says that the 911 will continue to be the main racing platform. You can be sure that someone else will race the Cayman if Porsche does not. When the Cayman was being developed, it was rumored to be faster around the track than a 911. It is certain that with a little tuner ingenuity that the Cayman could become a very fast track car.
