Diggitydog89 - We are running V8 Roots style supercharger becuase it provides great reliable liniar torque. Perfect for drifting. We are not necessarily looking for the highest hp #s but what we are looking for is the highest torque throughout the entire rev range. That is what V8 SC provides. Almost max torque at 2k is freakin awesome!
BRZZEE - We are running the Supra differential with the Tomei Technical Advance Trax differential that is just aweomse!
Ryaquinn - We are running a prototype FIGS Engineering Pro Angle kit for the FRS/BRZ. We are collaborating with Mike @ FIGS to make this a track tested setup. As of right now I don't believe he has a page up on his sight. However, I am most certain he will be releasing more information as soon as it becomes available.
