91 13BT, isn't just a 13bt. I thought 91's come with a 13BTT? I might be wrong, but. a 91 is an FD? is it not?

Fd has a 13B-RE not a 13BTT :P

IT is not worth the effort to go S5 in an S4 unless you have lots of money to spend on thing. But the S4 rotors are the best of the best. I use them in the RE's that see high boost as they are the strongest of the Mazda rotors.

the fd is the 13b-rew

cosmoes got the 13b-re

or am i wrong

interesting you use the s4 rotors, is it because of compression or somethign

the 13bre and rew are the same motors with the exception of a few slecte parts. But yes, you are correct.
S4 rotors are stronger than the S5's. They take alot more to damage the rotor. The S5's were made to be light so you can rev the engine more, but who needs that with big boost
