Owner reviews for brake discs

I did mine recently. Purchased new guild pins and boots from rock auto and replaced them while I was at it. For rotors I like Zimmerman, pagid, brembo or textar. And pad I like semi metallic, preferably pagid or textar. For this particular brake job I went with textar rotors and a combination or trw and textar pads. Took me roughly 2-2.5 hours and cost me about 680 CAD. I flushed about a L of pentosin dot 4 through too.

I upgraded all four rotors to bigger AP Racing vented discs, upgraded my pads, added steel braided brake lines, AND replaced my air filter and did an oil change for less than what my local Porsche dealers wanted to charge me to just replace my front rotors and pads.

Of course Brembo is reliable.

I go with Centric premium rotors and Stoptech pads and I like the setup, Centric makes the rotor blanks for Stoptech big brake kits, I got turned on to them when I had my E46 M3 and that was the recommended setup for daily/hpde/autox use.

Use the Powerstop kit. I have them on 3 personal cars (all around) right now and hundreds of customer cars. Not one comeback or complaint. Metallurgy on rotors is good as long as you do a nice break in period and burnish pads to rotors.

Running DBA 4000 SX rotors f/r on my '05. Stock calipers.

I have been using r1concepts brakes since my first car over a decade ago. There brakes can be found at jegs, amazon and rock auto. Compared a 2021 receipt to current. I don't have any experience with powerstop. But r1 concepts brakes are way better then factory I've gotten metallic and ceramic pads the eline and geo line of rotors. Geo was so good. Typical rotors in the winter when you park in the garage and the next day the first brake has that squeal where your breaking the rust off of the rotor the geos never had that problem. I always got drilled and slotted and it definitely significantly improved breaking and I never had an R1concept rotor fail.

Zimmerman rotors and Hawk HPS pads. Rotors are not drilled or slotted. The car stops on a dime and just saved me on the highway yesterday. This was the first modification I did and I'm glad I did it.

Only run oem rotors so far. Haven't been able to find decent oem replacements.

I replaced mine with Power Stop rotors and pads at about 60k and noticed zero difference in braking after. They also only lasted 20k miles before the rotors started to warp. Just put OEMs back on. Absolutely not worth it.
