anyone has experience with them? i am looking for replace my rear rotor on my MR.
my car is for DD only.

 

DD only, they're pretty good for the price since they're pretty cheap. I ran them on my IX.

 

It doesn't really matter for DD. Centric blanks are even good for track use.

Are the rear rotors of the MR two piece?

 

only front rotors are 2pc, rear is the same as gsr.

 

The question that I have here is are those single piece ones good for use on 2-piece front ones as well?

Yes, Fedja, the dimensions are identical (because the calipers and brackets are the same across all sub-models of Evo X). You can put two-piece rotors on a GSR and/or one-piece rotors on an MR.

 

Thanks man! I guess, I could do that for a little while, but as soon as I started to be faster, National level guys would complain, so I will have to go back to the OEM one$$$....

That, folks, sums up SCCA autocrossing perfectly. People would protest a car that had parts that were worse than OE in every way, simply to move up a spot.

Lucky for me, I was always close enough to dead last to never have to deal with it.

 

when you guys change the rotors, do you guys change all 4 or just the fronts. i know the most stopping power are from the fronts.
if its not worth it to change the rear rotor, i will just replace the all 4 pads and the front rotors only.

 

You make a call depending on conditions of your rotors (front or rear). If they need replacement, you replace them! If you can just turn them, you do that too. For mostly DD you can get away with slightly worn ones for a while too, but if you are chasing tents and milliseconds, every bit helps everywhere!

As of most of the braking is done in the front stays, but EVO X wouldn't have huge rear breaks for no reason!

I worked at a parts store with Centric Brakes.(sold the product for 2 years) I strongly recomend them. I would use their Economy rotor before turning my OE rotors if in $ pinch. The reason is less metal equals less heat transfer. Hotter brakes more likly to get a pulse. Now Pads I could talk about also.

 

Care to explain what you mean by this? Which rotors have less metal and what is that pulse thing?

Thanks!

Fedja

 

The brake pads or turning the rotor reduce the mass of iron. This means less heat capacity to absorb the braking heat which means hotter temperature which reduce brake life.

Also - hotter rotors are more likely to generate brake judder from overheated pads.

Also note - less mass is one of the easiest ways for cheaper rotors to be made. Less iron, lighter to ship etc all adds up the pennies.

I really wonted the answer from the CAParsons to understand what he meant to say, not explanation on how this actually works...just what he wrote!

Thanks anyway!!
