I'm going to start with some criticism... the M3's rear bumper doesn't sit flush with the fenders. That would drive me nuts! I also feel that it has too much of an angle from where the flares start, making it look like a Z3/frog from the front pic.
The other E90 desperately needs mods. The Mtech kit does nothing for it since all your attention goes to the most horrendous stock wheels you can get.. in fact they are not even stock for a 335, but a 330i!
But now onto the good stuff... big respect for your E90 collection and the club you've started. It's hard maintaining and QCing a group when you're lonely at the top. Keep it up and I'm excited to see more content from you!
