are the rotors in the rx-8 lighter than the ones in my s5? if so would they be swappable? any performance gains? other than rotors any other parts swappable from the rx-8 that would be swappable with my s5 for performance gains? thanks

Yes, the rotors are lighter. I don't remember the exact weights. They are also higher compression.

They are swappable, but with effort. The Renesis engine uses three oil seals and a keystone side seal.

If you search for "renesis rotors", you will get the details. Other then that, there's really nothing else that can be swapped over.

 

thanks for the info, would the rx8 rotors improve performance on my s5?

 

Mazdatrix is doin this, I remember reading their article, they were having a bitch of a time making better numbers using RX8 rotors in S5 housings and last time I checked they were having trouble figuring out why...

 

well i will wait until they get it right and do it then. until then i will just wait.
