I was reading about a 1000 HP drag car (13B) ( http://www.rx7club.com/showthread.php?t=182522&page=16 ) and saw that the ceramic seals were aftermarket pieces from NRS up in Canada. ( http://members.shaw.ca/nrsrotorsports/index.html ) I looked them up and see that they do re-chromes as well on rotor housings. Very nice work. Worth a look anyway. Lynn E. Hanover Just out of interest Lynn, how much do they charge? George ( down under)
