Dedicated Rotors for Track Use?

Those are very good points. I really hate those rotor locator screws.

I've replaced mine with Flat head socket Allen machine screws. Installed with a touch of never seize.

The locator screws are not at all necessary... they only help align rotor/hat to hub. Your wheel and wheel bolts do the heavy lifting for that purpose.

If using track-studs instead of bolts you can easily ditch locator screws as hat/rotor will line right up when you slide wheel on the studs (if they'd even move at all during removal). But if you've got 'em, use 'em and since they have no dire mechanical function, coat the he!! out of the threads and backside of head w/ anti-seize and you'll be fine... Even driving on heavily salted winter roads (ask how I know...). Torque spec on the locator screws is super low too as I recall.

Otherwise, not sure SS, even 416, would be my first pick for caliper/carrier studs considering application / alternatives.

Again, I'd just run PFCs on street or if you only do 2-3 DEs a year then go ahead and swap when ready to use.

Good luck

Good luck

Tarett studs are out of 17-4 though 416 machines better and I believe takes treating a bit better.
