Germany's ATT-TEC has developed a new performance package for the latest generation BMW M3 models. The main event of the firm's tune is the addition of a compressor and a unique exhaust system that give the M3's 4.0-liter V8 engine an 80HP boost for a total output of 500 horsepower. ATT said that the price for engine retrofitting is �11,749 or about US$ 17,600, including installation.
The package also bundles a KW coilover suspension Variant 3 priced at �2,029 (US$3,050) and 20-inch alloy wheels wrapped in Michelin Pilot Sport 2 rubber size 245/30 ZR20 up front and 285/25 ZR20 at the back for a total cost of �3,475 (US$5,200).
The tire set is completed by 20 mm distance washers (�393 or US$586) on the front and rear axles.
An interior styling kit with carbon fiber parts or for the more adventurous, decorative Swarovski crystals, is offered as an option.
