What 2003 G35 coupe parts would fit a 2008 M45s?

Hi there.

I have a 3rd kid on the way, and I think I may need to make the move to a sedan... or a minivan.

I love my G35 coupe, and I would like to see if I can take any pieces of it with me if I were to migrate to an M45. These are some of the key bolt-ons:

3.9 FD ratio
350z shocks
Berk Test Pipes
Crawford Plenum
Eibach Springs
Front Camber Kit
HKS Hi-Power Exhaust
Rear Camber Kit
Stillen CAI
Stillen Swaybars
Transgo Transmission Valve Body Kit
VLSD pumpkin
Z Tube

Any input would be appreciated!

Thanks,

Clint

The Transgo kit can be put on the M45. With a bit of work the 3.9 differential can also be made to fit, but it will require new axle's on the output and a small bit of work on the input side of things to mount up right. Stillen sway bar's probably wont transfer since the body is a different size. Plenum wont work at all since it is a completely different engine

I also cant comment on long term reliability if you put the different rear differential on the M45, since the new axle's will be far smaller than the M45 is supposed to have.
