from a previous post...
"The "Supposed" Mazdaspeed distributor for Australia is a "Baked Enamel Shop" with a guy who used to work as a mechanic at Mazda! He wasn't real interested - saying bascially the cars great as it is - any perf. gains are trivial and not cost effective! "
No-one has had any luck with mazdaspeed in Aus. Even their jap web-site is WAAY out of date.
