The R and the S probably have the same weight limits on suspension. Both front and back are Air so you should be able to pump them up for your weight. Both the Zeb (r) and Fox 38 (s) are good choices for heavier riders as them have 38mm chassis. All models have 38mm forks on so no better on the...
Upgrading mountain bikes is much simpler than motorbikes. Most things are interchangeable (not all like T Type mechs). There are only really 3 or 4 suspension manufacturers and they are all interchangeable as a unit (fork or shock complete). The base level Fork and shock on the R model are good...
