Hmm, I think that will come under Construction and Use / Homologation regs.
No problem fitting as aftermarket, but I'm not sure can be done as part of standard production. Needs someone who knows the rules better than I. Aero Racing can certainly fit them, but that would come under aftermarket AFAIK.
And before anyone chimes in with their electronically controlled settings on a modern, that's different to fitting separately adjustable items that a new user could err, make a hash of...
The type approval document I've seen dated 21/12/2017 essentially covering the 5 link rear suspension changes for Roadster mentions only front discs and rear drums under the brake section. Wishful thinking but maybe there are more recent approvals covering brakes for this model.
