Welcome man. I got in yesterday, but didn't have time to install it. I'll be sure to comment on it whenever I get it in. We have a thread in the 02-06 Engine performance section on TB spacers. Just FYI, your competition also recently joined as well.
Good quality parts:
Can't wait to install it man. Fast shipping, great prices.
What else do you have in mind? I know us 02-06 Altima guys are looking for a Front strut bar, but not sure how economical it'd be on a CNC. Problem with most bars is the fitment. You have to grind the intake manifold to make it fit

Also interior door sills (like where the door shut on, I can't remember it that's what they're called), but those would be better done with a waterjet (if you have access). I'm sure we could think of some more items that can be made.
