Hi guys,

Just about to place an order on Atkins Rotary's apex seals. But I know RxParts's have a good reputation here. But $200 vs $500...

What are the best, overall apex seals? What do you guys run on your single turbo 300whp setups?

 

I run stock apex seals in my FD. Its right at 400hp and I autocross it. It has 3 seasons on the motor.

 

There is no best. Your seal choice should match your application and use of the car. For stock builds I use Mazda oem. They have a good balance of strength and longevity. However any significant detonation will break them. For anything modified I use RX Parts. They are super strong, yet do not destroy the rotor housings prematurely like some other aftermarket seals. In fact I have them in a customer's car with a full season of drag racing and when the motor was torn down for inspection the housings were still mint.
