Thanks,

gpflepsen, GM shortened the shifter handle length and modified the shift linkage a bit. Reviews I've read said it's nice enough that most people won't bother to get an aftermarket shifter, but it's not like it buttery smooth.

Also, the much respect Race Car Engineering ran a article on the Zeroshift, http://www.zeroshift.com/res/content...eering0204.pdf.
I for one would like to see the US availablility "RUSHED" and not put on the "back-burner"! 2006 seems WAY to slow to get this on our soil.

syncros are remove and your parts are installed - correct?

I have just read that they are using a new sequential gearbox, so that rules out C5R as a proving platform for Zeroshift. Man that would have been cool

The C5R uses a sequential shift racing gearbox (with dog engagement instead of synchros) so no clutch is needed for upshift/downshift. I'm sure there have integrated a n ignition cut on the upshifts and throttle blips on the downshift algorithms to help smooth things out and increae endurance for th long races. It used to be a Hewland box in years past.
It may all be moot when the new GM 6spd auto makes it way into the C6. Then you have the good ratio spread, full auto capability, and full tunability - with just a bit more parasitic loss. An LS7 would help on that end.
