Posting pics done by myself (so not professional) of my 550i Msport. Signature has mods. Thanks all for the help over the last year plus, off of it assisted me in making the decisions I did.
The ACS suspension is fantastic and really gives the "grounded" feel back to the relationship between road>tires>steering>hands and I suppose if BMW had used this sort of suspension to begin with much of the "feedback" criticism would be solved.
After driving 4k miles on my first F10 then another 2k or so on this one, the ACS exhaust takes some getting used to. It definitely fits the power in the car and has a great tone. Its nice to hear the acceleration. I always thought the car was too quiet prior. I prefer the tips over others but that's strictly personal taste.
I would like to see how the Hartge ECU turns out when they finish their testing, other then that, I couldn't be happier!
