X-drilled & Slotted Rotors CAN be cut!
Well as some of you know, i bought some x-drilled & slotted rotors by Zimmerman and about 2-3 months after installing them on my daily driver boxster, they warped. I torqued my wheels way too tight so they warped... stupid me, i went way over the 90 something odd lbs of torque that i should have had.
I asked on several forum if anyone knew if they can be cut and many mentioned that shops will not want to cause the holes and slots could break there rotor cutting tool
So, I went to my fathers shop to try and have the Rotors cut, Rather than cutting 5000th of an inch into the rotors like on any normal rotor, my father recommended going at 1000th of an inch at a time. We made about 4-5 passes on the rotor and the cut was perfect and smooth again!
So, if anyone wants to have there warped x-drilled & slotted rotors cut... you can on any run of the mill rotor cutting machine just as long as you make cuts at 1000th of an inch at a time till the entire surface is cut clean.
