Randman: No information about prices yet.
VenomRcR: They could be machined out of SSG carbon fibre but that would depend on the availability and price of the SSG material. They would most probably be more expensive and also heavier and not as stiff as the twill weave carbon fibre. I'm sure they would look good in SSG though!
MIP CVD's: Here's what I have worked out by measuring the driveshafts; if you use the front MIP axles for the MR4TC and the bones for the rear of the MR4TC then that assembly should fit the front of the SD. And as many of you have said the rear MIP CVD's from the MR4TC fit the rear of the SD perfectly.
SD front: TC front MIP CVD axle + TC rear MIP CVD bone
SD rear: TC rear MIP CVD set
Can anybody confirm this?
