Used Centric 60-28 instead of 60-32 rotors
Hi Jeff,
Hoping you still get notifications and respond!
I accidentally bought the 28mm brakes and rotors package from RockAuto. The brakes didn't fit my car, but the rotors looked the same to me so I used them and bought brakes from store. I later found specs and see there are some differences and wanted to get your opinion.
Are the 28 mm rotors going to be safe for us or do I need to change them back to 32 mm?
28mm front https://www.centricparts.com/disc-brake-rotor-121-44125
32 mm FR https://www.centricparts.com/disc-brake-rotor-121-44139
32 mm FL https://www.centricparts.com/disc-brake-rotor-120-44140
The picture for the FR rotor doesn't seem correct to me bc the tiny holes are not diagonal like the old 1 I have and like the left ones.
I messaged Centric and they said: Fri, 06/28/24 6:55 am Hello Brandi, We do offer directional rotors for certain models - The 121.44139 and 121.44140 have cooling vanes designed for them specifically, and don't have to follow the other look of the other rotors, so they are just a different design. They are correct though. Thank you for contacting Centric Thu, 06/27/24 4:38 pm Subject Product InformationMessage: Hello everything I've read says the rotors for cast 60-32 have 32mm rotors with directional cooling vanes and so the LH and RH rotors are different. I noticed the 2 tiny holes are diagonal on the front left but straight on the front right. I'm looking at rotor parts 121.44139 and 121.44140.
Thank you!
Brandi
