ATT Thunderstorm M3
ATT tuning retrofits the BMW's 3 series top model - M3 with a "Thunderstorm" power output. Not too finical in re-styling the BMW M3, ATT car specialist has definitely paid attention in increasing its performance.
After an ECU remap and a specially mounted exhaust system with optimized dynamic pressure with 4x90 exhaust pipes, the output data of the BMW M3 increases to the striking 500 hp. The responsive steering is ensured by a specially mounted KW coilover suspension Variant 3. ATT tuning has also fitted the sporty M3 with a set of huge ATT-TEC LeMans 20-inch alloys in dimensions 8,5x20 and 10x20 wrapped in Michelin Pilot Sport 2 tyres with size 245/30 ZR 20 and 285/25 ZR 20.
Additionally, ATT tuning is offering an exclusive interior pack with either carbon elements or Swarovski crystals.
