i am in the middle of conversion to 944T brakes. i will be running Carrera rotors up front and 944T in the rear. the used rear rotors i have are worn to 21mm. the manual says 22.6 is the limit. so new rotors it is
.
so to the question...any issue with running drilled in the back when the front are only vented? i eventually want to be drilled all the way around, but might as well make use of the new 911 rotors in the front.
of course depending on cost, i may just go vented in the rear anyway.
