the older subzeros had problems due to the spoke design from what I read, but Rota has fixed that, and other than the subzero thing, Rota's reputation has been great amongst Honda autoX crowds, lightweight and relatively strong wheels. Honestly any decent quality cast wheel for your purpose will do, here are some suggestions:
http://www.autornd.com has custom Rotas in RWD offsets/sizes, they're a lil more expensive than regular rotas but the cost of regular Rotas + spacers will amount to be the same.
http://www.teamdynamicsracing.com has a wholllee selection of offsets in various sizes, they're based in UK so you'd probably wanna call the USA branch first. FYI TD has a stellar rep amongst Miata crowd, lightweight and strong cast wheels.
