If their just replacement rotors than their the same OD,9.25'' as the stock units.
If you increase the OD of the rotor you will see a big change in the stopping distance!

My front rotor is 12.9'' & my rear is 11.5'',also changed the front caliper from a signal piston to a four piston,the rear is a signal 48mm.

 

They look nice regardles. Let me know how the long term use of these are

 

Didn't want to start a new thread but need new rotors and pads, and came across these https://www.amazon.com/gp/aw/d/B00L...--9----6-0&dpPl=1&dpID=518Qb4fvAdL&ref=plSrch

Anyone who installed from this thread have good luck long term? Thanks

 

I've run Power Slott rotors on my truck & on our old Mountaineer, they are good !

 

Good to hear. I just ordered them, for 60 bux it's worth a shot. Thanks

 

Got the drilled and slotted rotors installed. The seem to be of good quality. Haven't tried them out yet, was chasing a bad master cylinder problem. But I'm sure with new pads rotors calipers and mc it's going to be a huge difference. I'll report back when I getting driving.
