This is for my Toyota motorhome. I have found that aftermarket rotors fail quickly and am looking to find true Toyota rotors. Part number or place to buy would be greatly appreciated.

 

Have you tried LC Engineering? They lasted longer than the OEM for me. little pricey

 

There are several on-line sources of OEM Toyota parts, typically dealers who have an online parts presence as well. toyotapartsoverstock.com is one that I (and others on this board) use frequently. Google "Toyota OEM parts" for more choices.

 

Depending on your driving habits, After market rotors should not fail faster than OEM.
