Frequently Asked Questions
What pad compound works best with this polished rotor?
Organic pads are recommended on polished stainless finishes. Sintered pads will also work but may cause faster wear on the polish.
Will the 2008-2013 FLT rotor fit my 2014+ Touring?
Yes, if your 2014-2024 FLT has spoke or aftermarket billet wheels. Stock wheels on newer models may require the current-year rotor.
Are the mount holes drilled straight through?
No — the rotor mount holes are countersunk, so ensure your caliper bracket matches this design before installation.
Do these rotors need bedding in?
Yes. Bed in new rotors with progressive stops before hard braking to seat the pads and establish consistent friction.
