I installed my Rogue Engineering shifter today.. easy peasy and now my shifts are buttery smooth. Despite the shorter throw shifting is quick and precise with no hint of notchiness due to the weighted selector rod. The other day I installed my Intravee2 and KC420i Ipod adapter. It works just so so.. it makes music but the interface is buggy unlike my M3 or my 540 that I had one in. I may switch to the DICE Mediabridge, we'll see. Additionally I ended up with a pair of rear OEM wheels that I shod with matching tires for the front of the beast... they look great and since they're OEM I have no worries about shake or shimmy. So far the car is awesome and I still have a few things to install, PSS9's, Rogue X-Pipe, DVD based nav etc.
