I have heard of the 3mm race cleared rotors, how does that help with the car? Does it make it rev higher like 11Krpms?

 

3mm pertains to the apex seal thickness ... It allows it to withold more pressure without worrying about things .

Race clearanced rotors , well I've heeard th term but I'm not sure what it means .


I think you just shoved the 2 terms togther

 

3mm can hold more boost?

 

Yes

 

Will the engine break easier?

 

What does that question mean ????

12A's have stock 3mm seals .. some of the RX2's had 7mm apex seals ...

 

I meant, like will the engine's reliabity go down?

 

Why would it ????

Its allows the engine to withstain higher tolerances before failing ... If anything its helping it

 

Is it expensive to do I heard you need machinery to do that?

 

You have to machine the rotors to accpet 3mm seals yes . I am not sure how much it runs to do it exactly .

I would call Scott up at Mazsport and ask him . One of the only locals that gets it done .
