It's not often that we get to see French tuning houses take on German sports cars, so when we stumbled upon the Delavilla-prepped Porsche Cayman R1 it immediately captured our attention.

One of the lesser-known tuners from France, Delavilla was established in 2007 and focuses exclusively on Porsche models currently offering complete programs for the Cayman and the 911 coupes. The company says that it is also working on tunes for the Speedster, the Cayenne SUV and the Panamera saloon, with more details to be released at a later date.

Back to the Cayman-based R1, the coupe model was revealed at the 2011 Lyon International Motor Show last month and it proposes a comprehensive exterior makeover along with a choice of power upgrades.

The obvious exterior changes start with a wide bodykit that includes front and rear bumpers and fenders along with side panels, which add 120mm (4.7-inches) to the Cayman's overall width up front and 180mm (7.1-inches) on the rear.

The car also gets a bespoke set of quad tail pipes, LED daytime running lights and larger multispoke alloy wheels in the same color as the body.

Delavilla notes that it offers a great number of options ranging from scissor-style doors with a fingerprint recognition system to a transparent engine cover.

Inside, the French tuning house adds a pair of bucket seats along with Alcantara trim on the steering wheel and gear lever.

Buyers can choose from three different power kits that lift output to 340HP, 385HP and 420HP, though the most powerful option is only for those than plan to use the car on the track for racing.
