ATT tuners have released their latest package that sought to create a version of the BMW M3. Dubbed as the Thunderstorm M3, the car has had its appearance and performance enhanced.. The Thunderstorm M3 doesn't have a very stylish look. What makes it outstanding is its powerful performance tuning. Engine is improved due to its inbuilt compressor and engine software optimization.
It has a unique exhaust system with optimized dynamic pressure (available in two sound variations) for 1,355.00 Euro with 4x90 exhaust pipes increasing engine power up to 500 hp. The price for engine retrofitting is 11,749.00 Euros, including installation. For better handling, the car's chassis was upgraded. Its KW coilover suspension Variant 3 (2,029.00 Euro) guarantees better road-holding, even at high speeds.
Body overall width is increased due to its huge ATT-TEC LeMans 20-inch alloy rims. ATT gave it a set of 8,5x20 and 10x20 alloy rims with Michelin "Pilot Sport 2" 245/30 ZR 20 and 285/25 ZR 20 tires that cost 3,475.00 Euros (mounting & balancing included).
The package also offers 20 mm distance washers (for 393,00 Euros) on the front and rear axle. Buyers have the option of choosing an interior packet for the passenger cabin with either carbon parts or Swarovski crystals.
