Stacy, I was going to PM you, but since you already got someone giving some advise here, I just post here and see if there'll be other people agree/disagree my opinion...
Besides your front contour line, I would say, yes, it looks good, however, one of the reason I like the 02+ style is that it also had the coverings on the door area, so it's more flush to the body line, instead of our older style's "taper" contour. I wouldn't say I hate the original styling, but be honest, it's a really dated design. As shown as your third picture, especially with us who had the wider offset aftermarket front wheels, it looks kind of weird. The 02'+ panel is cleaner...
I'm also not sure about the lower ground clearance, I would think it'll not be too favorable to people who hits the track regularly, from the difficulties of fitting a jack underneath the car and also in case of minor off track incidents. I also thinks that the side skirt actually look wonderful with the WW front lip, but then the rear now is too short and again, the car body lines being kind of dated. ( I don't know how many people noticed that, the 97-01 nsx, from the side view, you will see the front lip being lowest, then step up to the rocker panel, then another step up to the rear valance...) which, the 02+ is more flush, I know it is an objective thing of saying the 91-01 style is dated, admit it, if it's not dated, none of us will look into this post... (I mean, most people would be just like Ken(nsxtasy) and felt that there's no need for any aftermarket enhancement on looks.) Disclaimer: I'm not saying Ken's not right
Stacy, my point is if the lower the rocker panel too much, you will limit your kit only be interested by someone who already had an aftermarket lower clearance front lip, or who had a full body kit but don't like the particulart rocker panel of that company.(mix and match type). Since you developed the whole thing and I understand it will cost you a little bit for this R&D thing, the last thing you want would be narrowing your customer base, right??
I object the idea of having any vents, it will be just like at least 4 or 5 companies' panels. Stacy's kit selling point is a clean panel that will enhance the look of the car. I believed a subtle body kit will go a long way.
I need to say again, I'm very thankful of Stacy having an open mind to accept comments (good or bad) and I admire his bravery of going out and try something new.
