Rant on Centric Premium Rotors the 120-series

[SteveSRT8]

Good results are always a good thing!

Note that heat dissipation may be an issue with drilled brakes as you are removing mass from what is essentially a heat sink. Not always beneficial, once again subject to so many variables....

I just bought the 125 series Centric rotors for my BMW. Haven't Installed them yet. I've put the 120 series on numerous cars and haven't had any complaints come back to me.

My current front pads are Jurids that just lasted 89,000 miles so I decided to use them again.

I recently received a pair of Centric Premium rotors from Tire Rack, and they both weigh 12.8 lb, on my bathroom digital scale.

I've bought rotors from R1 concepts for 2 of our cars - excellent product and reasonable price.

+1. Checking run out and caliper alignment is a absolute must to doing a brake job right.
A cheap dial indicator set up and a good set of feeler gauges is all that's needed to check them.
Rotor shims are available from NAPA. Caliper alignment is usually rust in between the caliper mounting bracket and knuckle. A file or rolok disk is usually all that's needed to correct it, sometimes in extreme cases a shim is needed.
