ATT BMW M3 Thunderstorm

It’s hard to make a car as good as BMW M3 any better, but that didn’t stop ATT tuners from trying. And by the looks of things, it seems that they’ve done a good job!

The have picked the cabrio version of the M3 for the job and immediately got busy with its engine! They installed an inbuilt compressor, a new sport exhaust system optimized dynamic pressure and bigger pipes, and a modified ECU.


The result is 500hp ensuring much better performance for the handsome M3.

ATT, being professional, has also upgraded the car’s chassis and suspension via KW Variant 3 coilover suspension system, and 20-inch ATT-TEC LeMans wheels wrapped in 245/30 ZR 20 front and 285/25 ZR 20 rear Michelin Pilot Sport 2 rubber.
