I forgot how good these rotors are. C and D weight. Both from the same engine. Exact weights will be confirmed when my replacement scales arrive.

Apex seal clearance is 0.08mm using an old 12A steel apex seal which measured 2.91mm.

Some minor pitting on the front rotor from being in contact with water at some point.

The rear rotor was removed from a motor which swallowed a washer destroying the front chamber. The rotor was removed last weekend and was comp tested at 123, 125, 120 psi @ 250rpm prior to being pulled from the car.

The bearings are good on both rotors, as are they rotor gears.

These are good useable rotors.

Rotors look good but how do the apex seal grooves measure up?

The front rotor is 0.06mm to 0.08mm on the apex seal grooves when measured at the ends.

The rear rotor is 0.04mm to 0.05mm on th apex seal grooves when measured at the ends.

This was measured using a brand new RB carbon apex seal in the groove (albeit 13B as the pack was already open for my 13B RX4 motor build).

Good 12A housings available as well. S2 style with square block on the top, not the S3 H style.
