Apparently all the bolt holes are there and you just need to get the necessary parts, am I correct on this one?
here you go, it was on the E90 3-series DIY thread, a parallel thread for non-M3 forum
anyways, this is an awesome write up. You do need to source your split seat back though, but yes, then you need to just wire up your cable and release. Seems pretty straight forward. There's a few E90 black leather rear interiors for sale on the M3 forum here, check the interior for sale thread (you'll want M3 Novillo leather vs the crappy non-M3 leatherette)
someone should do this!!!
