That has to be one of the best if not the best write ups I have ever read on e90. Normally I see a post this long I just skim through it. This one I read every word. Well done sir!
Your car sounds like a beast. It's nice to have a car that is better then you are. You will become a better driver because of your car.
Very nice list of mods you have on your car.
I will be looking for your next write up
Edit: Just looked at your pics. HOLY SHIT. That is a gorgeous car. It looks fast sitting still
