Ah, yes, who wouldn't love the reduced mass? But monoleafs are terrible at windup control (launches, or heavy braking forces), and Chrysler Engineering has tested nearly every composite / fiberglass leaf out there - they desperately wanted to use them on minivans, where the rear axle is just along for the ride. But every one failed durability testing (at the "ends", not surprisingly) so they seem to be good only for single-purpose race cars, not street cruisers that actually might hit a pothole.
