No personal experience, just an impression that the 3mm seals being heavier may cause more wear on the housing walls than the ligher 2mm. I know they are used, but I have also heard that some milling of slots by some parties is less precise than needed. But, if you are having good results - I certainly wouldn't tear down the engine to replace them. {:>)

Subject: [FlyRotary] Re: V shape Apex Seal Slots?

I have considered that, but not really keen on using 3mm seals and the one rotor does have its slot mashed together although I imagine that milling it to 3mm would remove the damage. I think I am going to spring for NEW rotors even if the old RX-7 9.7:1 ones.

May I ask why? (says he with the indestructible 3mm seals installed)
