Went on rimtuck.com (great site! thanks
Mr93z32) and looked through the 300ZX pix, the only ones that kind of caught my attention were:

and in second place:
TTkickedin: I'd like to stay around $5,000, maybe $6,000 as my budget. I looked at your 3 suggestions:
-Work Emotion CR-KAI: I'd choose over the other 2
-MB Battle: was ok
-OZ Futura: was a definite no
What I liked about the Emotions over the Battles is the fact that the spokes don't end at the edge of the wheel, instead, there's an uninterrupted ridge that goes around the whole wheel. Also, I like the look of the 5 dual spokes over the equidistant 6 spokes.
Mr93z32: It's funny you should mention Rotiform because I really liked one of their wheels and I actually called earlier today for a quote. They told me about $1,600 per wheel for these:

It has the concavity and lip that I'm looking for and they're within my budget (albeit on the VERY high side of that budget)
As for a quick glimpse as to what wheels I wanted (and you'll see I've bounced all over the place), at first I wanted to get wheels that were on high end cars from the same era of my '91 Z32. That landed me on these Lambo wheels that I fell in love with:

After more searching, I landed on these and was committed to having them:

(Look at that concavity and that lip!

)
Started doing research on the specs and found out that not only were they rare and expensive, they had a different bolt pattern than my Z. I considered getting wheel adapters to solve that issue, but some people advised me against it due to the amount of power my car has going to the wheels. So I started looking for a company that would copy that wheel and customize it to my Z. That's when I found ADV1 wheels and their ADV-X program. I had a conversation with them and they quoted me a surcharge of $6,000 for the design of the wheel, then at least $8,000 for the wheels themselves

I wasn't going to spend that much money on wheels, and although I liked these from their collection:

they cost about $8,500 for the set and the wait is months. (notice they look similar to the Rotiforms, but 2x the price)
Feeling frustrated and beat, I've started considering either an Infiniti wheel (keeping in line with putting the luxury line wheel on the parent brand like I did by putting Audi wheels on my VW), like the G37S:

OR

OR the IPL wheels:

(went to the Infiniti dealership and was quoted about $4,800 for that set)
OR some other cheaper wheel that has concave and lip until I can afford the final set of wheels that I want.
So I come to you guys for some suggestions and guidance, and hopefully from this thread I can find a good set of wheels for my car. So thank you in advance!
PS: I want to have wheels on my car within a couple of weeks so my body guy can roll/pull the fenders accordingly
