Here's an article from Autocar, on the car:

If you're finding the regular Cayman S a little ordinary, then it might be worth giving German tuner TechArt a call - it has just launched a string of modifications that can take the car up to a cool 370bhp.

Three upgrades are available - the first provides a modest increast of 15bhp to 310bhp, the second (involving a switch from 3.4-litre to 3.6) boosts grunt up to 340bhp, and the top spec sees the same engine bored out to 3.8 litres (as well as new pistons and crankshaft) to provide 370bhp.

TechArt can also upgrade the car's suspension to cope with its extra performance, and the almost-compulsory body kit is also available, including a new front grille and spoilers.

The Cayman S is already a favourite at Autocar - it came out on top against stiff competition in our recent B-road Baftas supplement.

Nice of TEchArt to offer performance upgrade for the hp crazy dudes out there.
