if you had to modify a G37 Sedan...
 

And couldn't sell it to buy a Z, what would you do to it?

Depends on what you need it for.
Basic mods can still be applied, wheels, exhaust, intake. I know there are some nice lip kits (or even front bumpers) for the G37, or maybe do some nice rear add ons with the exhaust.

Boost it!

Pretty much the exact same things you'd do to a Z or G coupe. It's the same motor / tranny.

If you can't boost it. Do intake, HFCs, CBE, tune and some suspension mods. :tup:

Supercharger would be fun... Right now I'm getting the exhaust right. Not satisfied with Berk HFC and Tanabe axle back. Need deeper and less rasp

That is what I'm doing to my G.. I think it is cheaper to buy a used Z though. :rofl2:

Yep, the 335i looks enticing because with bolt ons and tune you're at 400whp

For a sedan, I'll just get lowering springs, spacers for the OEM wheels, window tint, and killer audio. No loud exhaust, no body pieces, no aftermarket wheels. Ok, maybe a set of Work Gnosis, but that's it :tup:.

Hey man why not look at my car, LOL I did everything mins headers :) We talk , :)
