I may need to have some early pedrinis machined to fit my late rotors.

Is this an advisable thing to do?

What exactly needs to be done?

Do I need to take them to a machine shop?

Hubcentric rotors are only on the front right?


thanks!

Yes hubcentric fronts only. Take the rotor to the machinist, and have them turn the rim to fit. The machining has to be very accurate. That is what the factory did.

IIRC, the back (inboard side) of the wheel needs to have the center hole opened up. The early ones have a taper in the center hole, the late ones have straight 'walls'.

early/late

Simply machine the hub centric ring off the rotor. Don't touch the rims. We do this all the time with late rotors that want to convert to 5-lug Fuchs.

true , but wich is reallly the best way hummmmm?? only 4 lugs . 4 cylinders, hes coming up short already

Thanks for the advice so far everyone .

I really like the idea of not machining the wheels, not to mention rotors are so much easier to come by.
