Hit the nail on the head. Most Honda-Heads in the states are inspired by the Japanese factory stylings, and most Honda-Heads overseas (not just Japan) are inspired by the American aftermarket.
Oh, and like my friend Zol said .... Bomex is the rice of JDM.
There are plenty of Japanese manufacturers that make kits that actually compliment stock body lines - Mugen, BYS, Top Fuel, Azect, Bugspo, C-West, HiRO, Seargent, Act Sports, Rando Sports, Aero Over. The list goes on.
But yes, back to the integra. Seems like a lot of money was put into it, but it's still ugly, IMO. Lambo doors, no matter how well done, never seem to work quite right. On his car, the headlights don't seem to line up with the "bomex" bumper. And stereo systems are fine for show .... but they're just not my cup o tea.
