They did, nismo, as in Nissan Motorsport.
You've went from talking about front lips and side skirts to spoilers now.
You bought an oem wing for your car as it came without if I remember correctly. Why did you do this? Because it looks better?
Of course it's all down to taste but at one point the nismo kit was one of the most desired and expensive kits for zed. It still is expensive but there is many many replicas on the market now which is why we see more cars looking like this.
If you had followed my build thread you would have seen what's happenig with my car and infact the wing is coming off the car for something my larger and less discreet but with much more purpose.
The full body(doors and wings, boot etc) on my car is getting changed to carbon fibre over the next year to drop weight for track fun as the zed is fat and needs a diet.
You need not make assumptions of people's IQ because of kits etc as it will reflect very badly on yourself, and, as you said you were older I thought you may have been much wiser than to make such silly remarks.
I'm out....
