RX8 rotor & cut away for 3mm full height seals
A customer of mine in Russia is looking at running 3mm full height ceramic seals in RX8 rotors. Below is a pic of an RX8 rotor cut away showing the meat available in the slot as well as a stock RX8 rotor for comparison. Please note the cut away slot is not standard RX8 depth because they were using apex seals that are in between OEM height (FD) and RX8 height at 3mm width. Their slot in the cut away is 8.80mm or 0.3464", the total meat available is 12.20mm or 0.4803". This leaves approx 0.1339" to the bottom of the casting. The full height slot should be 0.385" deep leaving 0.0953" of meat remaining, almost 100 thou. From the picture the slot would be deepened another 0.0386", less than 1mm.
Hopefully this info will help others to make a solid decision when considering 3mm full height seals in RX8 rotors.
Thanks Dmitry for this excellent info!

Well Team the reason for the bump is because of all the very recent engine builds and all the apex issues. If most of the racing world such as speedsource is throwing 3mm in there and we are blowing our seals that this might be worth doing with ceramics and be done with it?
