With the M3 carrying the flag of the BMW 3 Series line-up, tuner ATT calls its new custom car – quite unimaginatively – the Thunderstorm M3. Fortunately, the Rastatt tuning specialists put much effort and creativity not only in design, but also in great driving performance.

The inbuilt compressor, together with engine software optimization, greatly increases engine performance. It is provided for by a unique exhaust system with optimized dynamic pressure (available in two sound variations) for 1355 Euro with 4x90 exhaust pipes increasing engine power up to 500 hp. The price for engine retrofitting is 11,749 Euros, including installation.

Driving dynamics are taken care of by an upgraded chassis, assisted by KW coilover suspension Variant 3, which guarantees better road-holding, even at high speeds.

20” ATT-TEC LeMans alloy rims increase overall body width. 8.5x20 and 10x20 alloy rims with Michelin Pilot Sport 2 245/30 ZR 20 and 285/25 ZR 20 tyres are set off by 20 mm distance washers on the front and rear axle.

Optionally you can order an interior package for the passenger cabin with either carbon parts or Swarovski crystals.
