Update 2009:
I bought genuine TRD wing for a price can only be described as a steal. I didn't really want to change the wing as I like how it is subtle with the low spoiler, but the price was too good to be missed. Strange how all my parts were purchased at low low price, it must be fate.
Nonetheless the wing is 2nd hand and it is painted in OEM Toyota black. In the beginning I thought I will paint it white but leave the mid-blade black. But I am not interested in spending money to paint it as I don't view the TRD wing as a real necessity to the aesthetic of the car.
Keen to feel what aerodynamic changes to the car, so I thought let's fit it as it is and see how it look like without painting it white:
Not bad, I think it actually looks interesting.
