Hello there,
I like all the DIY tips and tricks, quite nice to see budget conscience mods do work and turn out just fine.
That is what I am going for! 
Budget friendly mods that can still look good and grab some attention.
I was hoping you could provide a couple details as I am considering purchasing some wheel spacers. I posted up a couple questions on the 18" stock thread but no answer as of yet. As yours are stock 18" and 20 mm's... some questions for you if you do not mind...
I contacted CPZ performance and could not provide a definitive answer, unless I pull the front stock rim and provide an picture to them.
I noticed in your build images a picture of the front wheel and saw a "smaller" nut sticking out (not the studs for the attachment of the rim).
That little nut just spins right off, its for people to remember not to put the rear wheels on the front. But it comes off easily. Just store it with the other spare parts.
Did you have to remove that when installing the 20 mm spacer. Also which brand did you end up purchasing. Seems like the H&R Trak DRM (bolt on's) on the Stillen website state they do not fit the 370Z fronts. Hence the question out to you.
20mm spacers bolt on just fine. I have seen people rock 30mm up front with base 18's. I am not sure what brand I have. I bought them off a forum member who just happened to live a few miles away. I believe they are either H&R or z1 spacers..
Also how did you black out the door handles, was that plasti dip?
Everything that you see on my car is plastipped black, except for the roof. Thats gloss black vinyl. Here is my DIY: DIY: How To Blackout/Plasti-dip Handles
Regarding your purchase of the rear wing via WingTech, how was your experience dealing with them. How was the fit, finish and color match? I tried calling them several times now, left messages and send them 2 e-mails and have yet to receive any comm's back, hence my hesitation. [COLOR="red" Most sellers on Ebay have shitty customer service. Its just something that you have to deal with. They get spammers calling all the time too. So its better if they just have an email sent over, but those can take awhile to respond to as well. I have the base and shopped for many different spoilers. The sport one just makes sense and it looks great. I purchased the wing and it came 2-3 days later and wrapped up perfectly. Came with all the hardware, painted perfectly to match brilliant silver. (You just give them a color code). Anyways for $130-140 it cant be beat.. I didn't even drill mine, because I might want to remove it. Been on there for months..[/COLOR]
Did you go through their website or via their ebay listings?
They are both the same thing usually. Free shipping on ebay... Nissan 370Z 09 13 ABS Trunk Rear Wing Spoiler Painted | eBay
