The pic in the cat, shows a bracket made to bolt on the standard showa bottoms and this leaves a big gap with the caliper out further, so maybe more likely to flex thus out weighing one of the benefits of radials.
Maybe the only way is to change the fork bottoms for the big chunky cnc machined ones they have in the bottom pic, prabably a £1000 + £500 for calipers, not so cheap
