Tuners are all about giving people what they want. If you happen to want a stealthy looking BMW M3 Convertible with a significant power boost, ATT-TEC has a readily available solution.

To improve the stock M3’s performance numbers, the German tuner made use of the compressor kit from G-Power that costs €11,430 (US$15,000) to buy and €1,310 (US$1,720) to install.

Along with the help of a new sports exhaust system, the V8 engine’s output is bumped by 100PS to 520PS (513hp).

Chassis upgrades include new coilovers and a wheel set comprising 20-inch forged alloy wheels wrapped in Vredestein Ultrac Sessanta tires size 245/30R20 on the front and 295/20R20 on the rear axle.

The exterior is covered in a two-tone matt black and visible carbon-fiber foil wrap, which is priced at €2,600 (US$3,420).

The complete tune including installation for all parts will cost you about as much as a new VW Golf GTI in Germany at €26,573 (US$35,000).
