I'd think CSS could produce any coil, with proper specification.
Getting the price point to the $500-600 range would be crucial to the success of, for the LC crowd. Unless slow boating an entire container, don't see how that's possible to come close to.
I don't know what the shipping charges for the packages that just left AUS are yet, but it was estimated by my buddy there that after repacking the coils (arms are separated) $275-325 AUD, shipped at his cost, via Qantas. No charge for packaging or handling, though, and that's coils only. (He's no interest in taking this on as a compliment to his existing business).
Another consideration, at least from my uneducated perspective, is having corresponding shock travel criteria available, or a shock manufacture with products available for the various coils lengths, bolt on of course.
Have no clue how long the shipment will take, and I've postponed shocks until I can cycle with the tires I plan to run, order accordingly. Since the build has grown to include some type of work on just about every component of 450, it may be some time before the capabilities will be depicted, but I do plan to be very, very thorough and meticulous (thanks, :big thumb:. I was listening) in documenting.
Looking forward to the radius arms, too. Anxious to see in action. Another thread, perhaps, but hoping the result was worth the effort and expense.
