German tuner ATT-TEC, a tuning company that specializes in wicked programs for BMWs.

Their latest project is for the BMW M3 E93 Convertible. Comprised of a complete aerodynamic and performance upgrade, ATT-TEC went to great lengths to give the M3 some serious looking edge. Aesthetically, the tuner gave the sports car a matte black wrapping foil to go with new carbon fiber components, particularly on the hood, the grille, mirrors, and side gills.

Moving on to the engine, ATT-TEC fitted an SK I “Sporty Drive” supercharger system from G-Power to the M3’s 4.0-liter V8 engine, before reprogramming its ECU unit and adding a new stainless steel exhaust. The result of all the engine tweaking is a car that now carries an output of 520 horsepower, a 100-horsepower increase from the stock model’s 420-horsepower output.

As far as prices go, the aesthetic modifications cost €2,600 ($3,400) while the complete wheel-and-tire set hits €7,150 ($9,400) with the coil over kit costing €1,929 ($2,500). From there, the supercharger system will cost you €12,740 ($16,800) with the stainless steel exhaust setting you back another €1,595 ($2,100).

来自德国巴登州的改装厂ATT-TEC近日为一辆宝马M3敞篷版(E93)进行动力升级并为它打造了一个“霸气侧漏”的新外观。耗资2600欧元的车身乙烯贴膜使用了“蒸汽锤”磨砂黑色,用来包裹大部分的车身外部面板,并且在前机盖、后视镜以及排气增压器上采用了碳纤维处理。

此外这辆M3还装备了单块锻造的8.5×20 ADV.1轮圈,尺寸为前5.1,后11x20s,加上前245/30R-20和后295/20R-20的Vredestein Ultrac Sessanta轮胎。其他改装还包括KW Inox III可调绞牙避震系统、四轮定位以及将引擎输出功率提高了100匹马力至520匹马力的G-Power增压器组件,除此之外还有一套排气尾管直径90mm的运动型排气系统用来帮助引擎的“呼吸”。
