Can Granada rotors be drilled to 4 lugs?

Post #1 by Hot 6t Falcon » Wed Nov 26, 2003 8:59 pm

Guys (and gals),

I know that the four-lug drum brakes can't be drilled to five lugs, BUT how about going the other way? Can Granada rotors be drilled to 4 lugs?

I have a slug of four lug wheels, but am gradually moving to a Disk brake set up. I'd prefer to keep the wheels I've got.

Any ideas?

There's plenty of metal to drill to 4 lug, but to re-use the old wheels you would also have to turn the snout down to size. And then there's the issue of caliper clearance on the stock 13" and 14" wheels.

Just order a set of custom drilled one piece hub/rotors. It's easy here; guess similar in the US.

The 4 lug disc brake kit that California Mustang sells uses redrilled Granada rotors.

In th old days I use to buy Granada rotors on my Pinto's.
I would have to turn them down to 9 inchs but they worked bearings and all.
So it will work the other way around as well.
Pinto 1974-1980
Mustang II 1974-78
Rotors will work.
Now I cant say much about the other parts working.
But you might be able to get the Pinto rotors redrilled or purchase them blank.

Buy the way the Rotors off a AMC Grimlin are the same as Pinto rotors but hey are 5 lug ford pattern.

Dennis, like Falcon64 said. The Cali. Mustang Kit has redrilled rotors. Checkout out my webpage at for the part numbers.
