ATT are a relatively unknown German tuning company who focus largely on German brands such as BMW, Mercedes and Porsche. Their latest project has just been released, it’s a performance and aerodynamic kit for the BMW M3. Named the Thunderstorm, power figures peak around 500bhp.
In terms of the cars mechanics, ATT have added relatively little to release the extra power. A new compressor provides extra boost and an ECU change allows the car to deal with the new power in a more efficient way. As well as these 11,749 euro options, theres also a new exhaust to be had for 1,355 euros.
To stiffen up the suspension, ATT are advising KW coilover suspension at a cost of 2,029 euros. ATT-TEC LeMans 20-inch alloy rims finish the kit and add width to the M3. 8,5×20 and 10×20 alloy rims with Michelin Pilot Sport 2 245/30 ZR 20 and 285/25 ZR 20 tyres cost 3,475 euros.
Optionally you can order an interior package for the passenger cabin with either carbon parts or Swarovski crystals.
