+1 See below from another vendor. What do you think the power limits are for each material? I wanted a CF DS but I bet aluminum will handle enough power - well at least more me or most of the people here will probably ever run.I personally dont know of a shop that makes a carbon drive shaft, but im sure it can be had. The pricing on the aluminum drive shaft will be at the most 500. Im just quoting high until they get mine made. ONce its finished Poweraxel will be on the GB, so pricing may be even better.
Fenders and Roof would be custom.
For an full aluminum DS $350-475
For a full carbon DS $900-1250
Pricing is not confirmed yet.
