As mentioned before the most popular one is the f2, but tom has the roush kit now, wich is growing more on me than the f2, and please don't get me wrong the rs kit from f2 rocks.
I know it's cool to have a lotta options, but the more options you get, the harder it is to make the decision, because all these kits are awesome, i wish i had 5 foci and have each one with a different kit...jajaja......that's me of course.
I think that is true for many Concept drawing's. But the real pic is a crappy shot from the 05 SEMA show. I have seen a few other pics around that show it off better. It is very close to the F2 kit, but I like the rear wing better on the 3D kit.
