i did the SEARCH ......
and one thing i found out there's not a single spa yellow with mugen PAINTED hardtop, they are all OEM, can anyone post their mugen spa painted hardtop?

 

i think the mastergrade one might be ...look up that one

 

 

I have seen it on a few S2000s in Japan and it looks terrible. I would paint it black or leave it CF. No way in hell I would paint it Spa. Other color cars it does look better..

 

i have seen the mastergrade one, but then the color is not spa yellow
and they painted the whole hardtop yellow, i was trying to look for one that have black on the side......
i really want to see how it looks, but i can't find any

 

Might I suggest you find a good picture of a Spa with a mugen HT and have someone photoshop it for you.

 

instructions:

look at this website: http://www.mugen-power.com/street/s2000_0410/index.html

click under 'parts'
then click "aerodynamics"
then click "hardtop"

voila! The single spa yellow with mugen PAINTED hardtop. (also with painted CF hood and MF-10's)

 

Yup, that's considerably less than beautiful. Even if the sides were black I think you'd still have entirely too much yellow on the car - to the point of it being offensive. Stick with black.
