That's a JDP Engineering Carbon Fiber (google it up!) wing. Had that on my black S2000....can't wait to install it on my new white S2000 coming up this weekend. Its around $280 for that wing if I remember correctly.
REALLY REALLY NICE MEN! I love the car and the wheels. at 0.48 idk why but maybe its ben painted differently the door and the fender and hood look way off maybe the sun but other than that the car looks amaziG!!!
Why ruin a perfectly good S2000. Understand putting Konis on and perhaps a better sway bar as suspension improvements. Next I suppose someone will put a kit on to raise the car like of the 70s cars I've seen around that sit about 2 feet off the ground.
