NEW Centric Rotors Warped Outta Box?

Try torque it on the ground. your sports brake pistons might not be centered and pulling your rotor away from the hub so you might not have the right torque. Torque on the ground, drive around and torque again after 10 miles.

When I worked as a mechanic years ago. We used to come across rotors that wasn't true out of the box. Put them on a brake lathe to true them up. Some would take a little, others were a total lost.

You got 2 options. True them up or take them back and get another set.

I'm on my 3rd set of brake pads on my RacingBrake rotors. And I never had to put them on a brake lathe yet.

Forgestar F15's with built in hubcentric rings. Yes proper pattern.

The pads were reset to full piston in position in the rotors so they'd easily go over the new rotors; therefore, the rotor was also firmly against the clean hub. I'll try re-torque nonetheless.

Figured on the same 2 options and shot a video over to Centric of the steering wheel shimmy. I'd like to be compensated for new rotors or the cost of having to their QC duties myself of course.
