Kelsey Hayes calipers

Centric isn't exactly known for greatest product. They are one of the few who do offer the K-H Calipers at a decent price point. If you already have them. I have installed 4 sets without issue so far - probably good luck or perhaps they are getting better, Centric does use the lowest bidder so what was, might not be what is and who knows about tomorrow?
I am sure the Wagners have better metallurgy in their rotors aside from the fitment you mention.
