I forget what the shipping was on my intake, but it was HUGE!
Clearing stuff at the border yourself is definitely a lot better... it can sit there for a while, and the charge to clear it can add up. With the exchange, GST, PST & customs, it's often about twice the US price... but thats often still cheaper. (And you wealthy Albertan's don't have the PST).
Last spring RCO enterprises (London, Ont) had a good deal... find the lowest US price, show them the add, and they gave you an exchange of 1.6 or something (can really save on shipping).
www.wmsracing.com has some good deals too...
Awesome subframe connectors, and their lower control arms look good too.
As for ordering, Summit has been alright, and
www.hawaiiracing.com was really good (they took care of a UPS problem). I prefer not to send it UPS if I can... they have a monopoly on the market, they know it, and they just don't care.
