RxParts Apex Seals
Mazda seals offer a good compromise of sealing and longevity, but cannot withstand detonation. Other seals are durable, but cause significant wear to the rotor housings. We recommend these in everything from stock, to 700hp+ race cars, and everything in between. 
 
These are the seals used in some of the fastest Rotaries in the world. These seals are designed not to break, they will warp before causing any damage. These seals will handle a higher EGT than other seals on the market. Keep in mind that EGTs for cars running methanol are much lower than cars running gas (C16, Q16 etc)
