Thanks to Mike at Vivid Racing I was lucky enough to get my hands on the very first JP front lip spoiler for the 370Z to arrive in the U.S. I have had it for two weeks now waiting for it to get painted. I finally picked it up yesterday from the paint shop. This morning Modshack and I installed it.
I personally think that it is a subtle addition to the car and it makes the front end look much better. I also like the way it slopes up on the bottom in the middle like the stock Sport Package underneath spoiler does. And no it doesn't impact the Sport Package lower spoiler. I also think painted it looks a lot less bulky on the sides than it does in the unpainted pictures I've seen.
Here are some pictures.
