I measured two new 3-piece apex seals and they were 80.10mm long. My rotor housings narrowest points are 80.0020mm and 80.0049mm. The How to Modify your RX7 book says to sand the apex seals down to 79.90mm length for street use. Some people don't clearance the length of new Mazda seals and say they're fine as new. Ito says to clearance apex seals to 0.0015" narrower than rotor housing width. And others still say clearance it 0.004" to 0.0045" narrower than rotor housing width. Who is right?



The triangle piece is super glued to the upper piece. Should I super glue the lower piece to the rest of the apex seal, to make it all into a one piece? So I can sand it all as one piece and get a uniform cut on the apex seal? How thick is the super glue between the top piece and the triangle piece, should I subtract that out when computing the length?



Also, I assume I don't sand the triangle piece. Just sand the other end(s).



S5 n/a rotors.
