Well shoot, the A8 is looking better and better. Already bought my T56 so I don't think I will change directions, but if I hadn't I'm pretty sure I would have bought an 8HP70.
These guys have a controller, sequential shifter and a clutch emulator that makes the 8HP feel like a dual clutch manual. Using a rheostat, they engage clutch packs in the trans and make it work like a manual clutch would. Then they add a spring so the clutch pedal has resistance. After getting rolling you shift like a DSG, and use the clutch for clutch kicks (??). Must be a drifting thing. Either way, pretty cool.
Not sure I would go that way myself, but pretty cool tech. The fact that the SGE kit allows for different shift schedules really intrigues me though and would probably be the way I go.
