 Paul,

 What do you know about these guys?

 They offer aluminum housings and P-Port rotor housings.

 First I have never heard of them. I would not use their apex seals
 as they sound like steel. Steel is OK for drag racing engines but
 not for long term uses. It damages the expensive rotor housing right
 from the start.

 I would only use the stock Mazda cast iron seals or Iannetti ceramic
 seals. The Iannetti ceramic apex seals are also extremely resistant
 to detonation so there is no need for steel.

 The aluminum end housings look like Racing Beat's.
 The 2 piece 3 rotor aluminum center housing looks like a good idea.

 The p-port rotor housings are twice the cost of the SS tube welded
 in variety. Those rotor housings are imported from Australia.

 Also Canada does have some strange product liability laws so it is frequently
 problematic doing biz with companies in Canada. Buy with credit
 cards so if you have a problem you can dispute the payment with the
 credit card company within 30 days.

 Hi Steve,
 I have been in to talk to Adam. He seems to be a straight up kind of guy. I
am not sure of the seal material Paul mentioned. The Ianetti ceramic seals are
the durability way to go for long term life. I do not think you would have any
troubles with dealing with them.

 As for product liability issues; yes there is. But any time you deal
internationally there can be problems. A friend ordered wire wheels a few
years ago and when they arrived, the roll at the rim lip was galled up from
not replacing or cleaning up the rollers. It took hours to clean them up up
with a die grinder with a carbide burr and emery rolls. It was too expensive
to send back and the supplier would not assist, because they knew it. Unload
product that should have been tossed in the QC reject bin.
 As Paul said, pay with plastic. Goes both ways across the border.
