04-11 Rx8 Side Seal Set (N3H1-11-C11C)
We prefer the side seals Mazda offers which are longer, and require hand fitting so that you can attain a more accurate fit between side seal and corner seal which allows for maximum compression and no blow by. Every rotor is different so it is better to get them longer to custom fit each slot, these are also cheaper than the pre-cut letter versions.
You will need to remove approximately 0.05" (1.28mm) from each side seal.
Consider upgrading these to Cryo Treated Side Seals to allow for better more uniform heat dissipation, because these seals ride directly over the extremely hot exhaust port inside the renesis engine.Pro Tip: To check actual clearances use 2 springs for accuracy, but only 1 when assembling the engine.

Twelve OEM Mazda Rx8 Corner Seals and plug inserts.
04-11 Rx8 Cryogenically Treated Side Seal Set (N3H1-11-C11C-C)
Cryo treating this part is great because these ride over the extremely hot exhaust port inside the engine, and cryo treating allows heat to be dissipated more quickly and uniformly.

All of our apex seals are heat treated.
The material for these seals has been developed by David Atkins over his extensive racing career in order to exceed stock apex seal life and durability.
