Audi tuning specialist Nothelle, a performance house with a forty-year history of vehicle customization, has released a new package for the Audi TT. Nothelle’s new kit is designed for either the Coupé or Roadster, and includes enhancements for both the 2.0L TFSI or 3.2L V6 variants.

The flagship model is a twin-turbocharged version of the V6 quattro that delivers up to 520hp and 635Nm of torque. The package includes a reinforced clutch and a specially adapted gear transmission ratio for manual models and when equipped with the DSG gearbox the tuned TT reaches a top speed of 308km/h.

Power for the 2.0L TFSI is also improved, with four different output stages available ranging from simple ECU upgrades that yield 40hp increases, up to a complete rebuild that delivers 330hp and 400Nm of torque.

Engineers also added a high-flow exhaust system, a sports suspension system (25mm lowering), and 19 or 20in lightweight aluminum-alloy wheels. To complete the package, Nothelle adds a complete bodykit with a three-piece front spoiler, side-skirts and a three-part rear spoiler for added downforce. Follow the jump for our complete gallery.
