Almost 900HP in my M3cs! Forged Engine, less than 5s 100-200km/h 

There is some good content to be found in this video!
I decided to wrap whole build into one material. Not 2 or 3 (as it could be)!
From totally stock CS, through huge carbon fiber bundle and complete engine rebuild.
Tuning showed us almost 900HP…
3 different engine maps - lowest gives us 550 HP - it’s enough for morning groceries drive.
Highest map will let you try with Porsche, Audi, Motorcycles and other inventions!
100-200 under 5s? Let's check it!
Completely new, custom interior, few nice touches and details. New exhaust system and for desert... new wheels, that fit just with millimetres.
Lowered, folded and awfully powerful CS will be given away to one of you.
More info in the video!
see ya!
High five!
