found a set of polyurathane A arm bushings on ebay. much cheaper than a Perrin PSRS setup and will still get rid of that sloppy rubber mount. What I want to know is if these bushings are the same from 02 on up thru 06? bushing kit says it fits an 02 thru 05 wrx, I have an 06 but know most part on these years are the same , is this one of them? I see that Perrin does have two part #s between 05 & 06 wrxs , but maybe just the mounting is different.
