BMW of Bloomfield -oem

getbmwparts.com for 99% of my OEM parts.
AutohausAZ.com for 1% of my OEM parts. (O2's, alternator, control arms, coils, plugs)

Edit:

RaceTechnologies.com - Brembo parts (friction rings, McLaren hardware)
Vortech.com - S/C stuffs
ChampionMotorsport.com - Tubi exhaust stuff
RoadwayWholesaleTire.com - Best prices on Bridgestone Dueler's

ECS Tuning - My one stop shop.

ECS Tuning - when I have an order of a bunch of stuff, so i only pay for shipping once, and tax free obviously

Local dealer/Craig @ Open Road in Edison - for smaller OE parts orders, that i wouldn't want to order online and pay shipping

FCP Euro/Pelican Parts - Bought some misc items from them in the past as well

Most of my parts come from AutohausAZ, Dealer only parts I get from Open Road BMW/ BMW of Edison.

Hmm.. any favorites for parts in Canada? I'm an American trapped in the seedy underworld that is Toronto, and don't want to pay huge customs fees for parts shipped from the US :P
