There are one piece carbon / aluminum seals, not too expensive, great for
racing. Good sealing
never hurt the rotor housings. Can handle some boost. Very light and can do
monster revs over 10,000 RPM. You have to be a memebr of the Mazda
competition program and provide pictures of your race car and finish sheets
from a number of events.

The very best are ceramic one piece seals. Scary light. Strong enough for
high boost. Not affected by engine over temps or detonation. Run with two
springs for tracking at scalding high revs and still have less drag than
stock or carbon seals. No downside until you try to buy them.
About $330.00 each seal, (you need 6). This is a bolt on 6 HP just from
reduced drag. No rotor housing wear. From Mazda comp. and after market
vendors. Carbon as well.

Newbie Question---for the "normal"13B NA engine, how do the ceramic  apex
seals compare with the other types of seals you all are using?  (I've*rarely
*ever read anything about their use in this forum.)
