I'm one of the "pissing contest" guys that got involved with in this posting.
I was asked to reply to a picture because many on this forum know me for my rebuilding of the Kelsey Hayes 4 piston caliper brake systems, and suspension parts.
Have been doing it as a side business for a bit of extra income for over 10 years.
I kept track, and sold 32 rebuilt set up's during that length of time.
That's probably three a year, or so.
I gave up buying, using, Centric rotors when i was having problems with them.
Haven't purchased a Centric from anybody, anywhere, in years.
Maybe by now they have changed their machining to produce a better product.
That i don't know, as i haven't been buying them.
To the guy that asked about rotors, buy what you want, and find out for yourself, between the brands, if you do enough of these, like i have in the past.
