well, here's my update after going to my dealer (galpin mazda in sfv). i checked the prices for the mazdaspeed parts, heres what i got quoted at:
MS CAI - 750 (not available)
MS catback exhaust kit - somewhere around 1500 (not available)
MS Coil Over kit w/ rear camber links - about 2k
MS STS - around 250
that's not including the installation/labor charges. my jaw dropped at how much they were asking and i laughed when the guy at parts was giving me the prices. oh well, looks like no perf mods for me until im almost done paying off my car (boom02)
