This is the outcome of operation Thunderstorm which is successfully accomplished by ATT task force! It’s based on a BMW M3 Cabrio and it comes with a significant power upgrade. The tuner has not anything on the body, mainly because it’s already one of the coolest looking cars out there! But what they’ve done with the engine is quite remarkable.

The high-revving V8 engine of the Thunderstorm M3 is garnished with a compressor, a new software for its ECU and a unique exhaust system with optimized dynamic pressure and 4×90 exhaust pipes which also has two sound modes. The result of this modifications is a healthy 500hp.

Enhancing the car’s handling to cope with the extra power, the tuner has equipped the M3 with KW coilover suspension Variant 3and fitted it with ATT-TEC LeMans 20-inch alloy rims wrapped in Michelin Pilot Sport 2 tires size 245/30 ZR 20 and 285/25 ZR 20.

The cost of complete engine tuning is 11,749 euros, while the suspension kit will add 2,029 euros to your bill, and if you want the wheels, they’ll set you back another 3,475 euros.

ATT also offers optional interior trims in either carbon fiber or Swarovski crystals.
