Can anyone out there tell me where I might be able to find a set of rotors
for a 99 F150 4wd. I need them without the drilled bolt holes. I"m wanting to
customize the wheels so I need to drill my own holes.

 

HUH??

Your no longer going to have Ford 5 hole lugs?


BTW there is a brake section on this site... https://www.f150online.com/forums/brakes-26/

Edited to add:
If thats what your thinking, and your not going with any other make lug pattern. If your going to try and make you own lug bolt pattern for your wheels. Then your going to have to machine your own rotors out of solid blocks of steel. I know it's a tempered steel so you will have to do alot of research to find out what temper you will want to make them. To soft and they will wear super fast, to hard and they will shatter. Your going to have to come up with a method to temper all 4 of them exactly the same too. (+/- 5 degrees or less. You'll have to heat them up evenly across the surface and throughly through the core to maintain temper as they wear down.
