I know there is the Kore3 hub adapter but i remember seeing somewhere that you could machine down a stock rotor to fit the C5 rotors on. Anyone have info on this? Is it as easy as just cutting the rotor around the studs? Also will doing this puch the wheel out?

Can be done , I was going that way until Kore we convinced Kore to make hubs for us.
Unless you sleeve the center you will lose the register for the wheel.
The wheels will move move the thickness of the rotor hat. .200-.375ish depending on the hats or rotors you use.
I do most all my own stuff but the Kore hubs are money well spent.

I left the bigger hub register stock and machined the C5 rotors to fit. The center bore was opened up, and the back mounting face was made bigger.
As Gerry said, it moves the wheel out the thickness of the rotor hat.
The Kore3 hubs were not available when I did mine.

Machined down B-body rotor.


this is the rear rotor, but you get the idea.

Where would i go to have a rotor machined?
"Unless you sleeve the center you will lose the register for the wheel" What do you mean by register? The rotor being hub-centric with the hub? (perfectly centered)

Most if not all GM rotors, after you cut down the to fit the removable rotor, the 3.06"ish" machined stub in the middle is not long enough to line up the Impala wheel.
They are barely long enough stock and the added thickness of a hat on top is usually enough to prevent it getting to the 3.06 part of the rim.

As for who does the machining, if you can't do it yourself and have to pay, then buying already machined, redrilled rotors would make more sense.
Kore is what I would do.

Also, when you compare apples to apples the kore full kits are pretty much "right there" on pricing.
Just over a grand but the ABS works, the hubs are billet, the car doesn't get wider, correct bolt pattern

I'll agree with Gerry.
I did all the machine and fabrication work and I still had 7-800 bucks in parts in the front alone. If you have to a local shop to do a one off job on the hubs and rotors, and fabricate a caliper bracket, it's gonna put you right there cost wise.
