Congrats dude!
Well, interior wise I got some 350z seats.

I wish I had nicer floormats.
Did my headliner suede to match the black interior panels.
Engine wise, I got an SR20 airbox to make it look closer to stock.

I'm gonna find a black interior light to match.
I also got coilovers a few months ago and did some suspension stuff and installed a VLSD (cleaning that VLSD was such a pain in the butt!)
That's most of it!
The rest of it is in my thread.

What's up with you in the car department?
