As far as we're concerned, the stock 420 HP on the E92 M3 are plenty for any enthusiast on the street but going on a full-on track like the Nurburgring might require some more grunt.
For that you have various tuning companies and one of the best in Europe is DM Performance. They created a 630 HP M3 and then sent it out to the guys from Motorsport Magazine to give them a first impression.
We saw them driving it a while back and now it's back, in the capable hands of the guys from Trackdays, that had the courtesy to take it on the Nordschleife, record the experience and share it with us.
Needless to say that the video below has incredible sounds and 8 minutes of pure driving experience, showcasing just how good the supercharger, Brembo brakes and custom exhaust can work together.
