I have no experience with these kits (and no connection to W&W). At
one
time I was considering modifying my LS8-18, but I've since found the
factory brakes work well enough if you keep them adjusted properly.

The Tost catalogue shows a range of retrofit kits for drum to disk
conversion, many with EASA or glider manufacturer approval. They
offer kits for S-H gliders in both 4" and 5" wheel form, and acknowledge
the space issues! No details are given on whose caliper is used, their
own or Cleveland, but I'm sure they will tell you if you ask.
