I actually signed up some years ago, but never got round to exploring the forum. Having seen it mentioned a few times in conversations, I thought i'd reacquaint myself.
I own a 330 sport convertible which I've owned for 2.5 years.
In that time, the notable mods have been:
Full OEM Nav retrofit,
Powerfold mirrors retrofit,
HSD MonoPro Coilovers,
Powerflex Bushes all round,
Genuine BMW Performance Carbon Airbox,
CAAT Carbon Strutbrace,
Storm Motorwerks V1 Gearknob.
Heres a few of my favourite pics. But I'll stick details of the work done in the projects forum when I get chance.
