Dortmund-based German Porsche specialists 9ff Fahrzeugtechnik GmbH have unveiled a new addition to their Cayman lineup - the Cayman S CR-42.

The CR-42 builds on the company's aero and chassis kits for the Cayman S, adding a 4.1-liter engine putting out 420 hp and 321 foot-pounds of torque. The maxi-Cayman hustles from 0 to 100 km/h in just 4.4 seconds, and from 0 to 200 km/h in less than 15 seconds. For customers in less of a hurry, 9ff also offers 380-hp and 350-hp versions.

The 9ff aero kit is fairly simple, comprising a high downforce front bumper with augmented air intakes and built-in splitter, and a rear diffuser cover adapted to the 9ff dual exhaust system.

The Cayman rides on 9ff's custom 3-piece center-lock 19-inch forged aluminum wheels, sporting 235/35 tires in front, and 265/30 tires in the rear. The "Hockenheim" sport chassis kit for the Cayman includes fully adjustable coilover shocks.

A full-on CR-42 sells for about $164,500 in Europe. If you're in the U.S., give Eurocar Boutique a call. More pics follow the break.
