Best Fucntional Spoiler?

nasm

It seems evo-r which is the one replica of Nismo is the good choice here. For both street and track use. In fact, I was looking for one, and luckily I got this thread (thanks to search feature). Because, I am looking for downforce on the rear, because when breaking from high speed before entering turns, I feel the car moving like a fish on the back. And I wanted to have spoiler/wing to hold the rear side of the car and add downforce.

Maybe those who have evo-r can share some feedback, I will be grateful if they do, because the nismo one is expensive, and evo-r might be the good option to go.
