My "in frame" rebuild

[infernosg]

A company called MMR used to make solid (delrin) subframe-to-body bushings. Other than that I'm not aware of any aftermarket options. As far as I know there isn't even a "Mazdaspeed" (i.e. harder rubber) option so stock is the only option. The bushings aren't that complicated so one with access to certain tools could make their own polyurethane or whatever material bushings.

Last time I checked Racing Beat's website, they listed the Mazdaspeed rubber versions of those bushings, which are supposedly 40% stiffer than stock. Not sure if they are still available though.
