Sure, I've been recommending the tall knuckles for years. They are lighter and you get a better camber curve with them. The trick is to use the upper control arms from www.firmfeel.com which have the tweaked ball joint angle.

I'm working on a project now where the knuckle is even taller than the FMJ one. The guys at Firm Feel are building me custom upper arms to make it all work. I'll post some pictures once we get it all together.
