Hi Lorenzo great vids! You engine is stock? Sounds flawless and powerful. I own a 325i as well but I'm experiencing some flat spots when I rev on low gears at about 1500-2500 depending ... did a remap and it's quite quick and an exhaust system with decat...she runs beautiful except those occasional flat spots.
How is it possible that it slides so much?! It's a heavy car on quite wide tyres with not so much power... How???? :D I have an old 328i with 225 r17 tyres and it won't slide as easily, my car has a lot of traction...
