S5 Counter weight question
 

If I were to use 9.7 rotors in my S5 T2, would I need a matching set of N/A counter weights or would it be fine as long as the weight is within two letters of my OE rotors?

If you are using S5/S6 Rotors, all the you need is an S5/S6 counterweight (doesn't matter from what kind of S5 engine).

You cannot mix and match s4 rotors with s5 counterweights (and the other way around).

Thanks for the reply, exactly what I was looking for.
