first off, i know this question has probably been answered but i cant find it. i am putting a s4tii together and i had to use n/a s4 rotors due to deformations of my s4tii rotors. my question is am i ok to use the front and rear counterweights from the tii assembly?or do i need the ones from the n/a motor?

 

You're fine. S4 NA and TII are the same.

 

thanks for the quick response buddy
