JUST want to know the hat offset i will need for a custom brake rotor? ( 313MM X 32 MM)

Thanks for your help

 

I personally don't know but search for old threads where people on here worked to develop a custom 2 piece rotor for the FD from Precision Brake.

This place does custom rotors for the racing industry but they are in the US:

They might actually have something for the FD since a few people on here have used them for racing brakes.

 

So,

what is the overall height of 99 SPEC FRONT ROTOR?

Thanks
