German tuning firm ATT-TEC from the city of Rastatt in Baden has optimized a BMW M3 Cabriolet (E93) for much more power and sinister looks.

Starting with the vinyl wrap job (€2,600.00), the company incorporated the "steam hammer" matte black finish for the majority of the exterior panels, accented by carbon fiber wrap on the hood, mirrors and rear diffuser.

The look is completed with a set of one-piece forged 8.5 x 20 ADV.1 rims in 5.1 design at the front and 11x20s on the rear plus Vredestein Ultrac Sessanta tires sized 245/30R-20 and 295/20R-20 front to rear. Further improvements include a KW Inox Line III Variant coilover system (€1,929) in the suspension. Installation costs €559 which includes wheel alignment.

Thanks to G-Power's supercharger kit (€11,430 + €1,310 inst.) power is boosted and additional 100 HP to 520 HP (382 kW / 512 bhp). A sport exhaust sytem (€1,455.00 + €140.00 inst.) with 2 x 90 mm diameter tips aids engine breathing. 

Added all together and the complete tuning package from ATT-TEC comes to €26,573.
