The M35 and M37 share the same motor with the G35/350z/G37/370z that are much more popular tuner platforms, so there's a big enough market to R&D and mass produce after market parts... the 45 is pretty much only in the M45 and FX45, neither of which are popular to mod (with the general public)
I would seriously consider a transgo valvebody upgrade, it'll make a huge difference in the aggressiveness of the shifting, as well as a custom Y-pipe with rear cat delete if that isn't already a part of your custom exhaust. K&N drop in filter with airbox mod, or a CAI, just be careful its not going all the way down into the fender if you're in an area that rains much.
Drop in one step colder NGK iridium plugs, and retune. unless you want to drop $$$$$$ for a set of custom headers or port your intake manifold that's pretty much it. There is a guy on the FX forum who's doing cams in his VK45, but its been a huge fiasco getting it right, and I think he's on his 3rd motor and just now getting it running.
