Brake discs Brembo or OEM Volkswagen

FWIW, I recently replaced my front rotors and pads at 40k and I have about 8mm on the back. At this rate, I'll probably have to replace the backs around the same time I do the fronts again. My rotors look nothing like yours though. Mine are smooth and no grooves.

I had the impression that those discs wouldn’t warp as easy as one piece discs but it looks as I was wrong. VW tried to machine my warped discs with them mounted on the car at one point but they failed so badly that they did not even want to show me the result. After that they messured the runout on new discs on the bench and found them OK. After the discs were mounted on the hubs they were messured again and that one of them had warped. That was the way they found the bad hub. I was quite surprised when I was told that VW did not have any tolerances for the runout on the hubs or the discs. I took for granted that they had quite strict tolerances both on the hubs and the discs. I don’t know if the eight piston caliper and the setup with opposed pistons makes the whole system more sensitive to warpage or not but that has been suggested. And to get this a bit more connected to the thread subject I can add that I have not found any alternative to VW original 365 mm floating discs at all. I was quite surprised to find them cheaper than the one piece 334 mm discs to my Passat W8 though.

Could be the hubs. Mine had an axial throw of 0,02-0,03 mm which I thought wouldn’t affect the discs. I filed a complainment to VW regarding warped discs and they blamed the calipers. Told me one of eight pistons was a bit sluggish. With new calipers and two sets of discs later they found what I had meassured before the complainment, a warped hub. The last pair have not warped after the typical 5000 km mark as before. So at least the floating 365 mm discs are very sensitive regarding straight hubs.

I put Brembo Sport rotors with EBC Red Stuff pads and ATE TYP200 brake fluid. Works great.

Got these on my Corolla, they're actually good for reasonably cheap brakes.

i was on the fence about buying them and i did a bunch of research and after speaking with my buddy who is a mechanic and owns a tundra he said that the powerstop brakes aren't great and if you don't have the money to do the tundra swap, to get the brembo rotors and either akebono or brembo pads. ive been driving with this setup for about six months and have had no issues. the braking feel and stopping power has noticeably improved.

The best stopping combination so far on my 08 sedan with 140K is Brembo UV Coated rotors and Advanced Auto Parts Carquest Wearever Gold Semi-Metallic Brake Pads Previously I had Zimmerman rotors and Hawk HPS pads, I got a grinding feeling/noise when stopping. The Carquest pads dust like OEM but for the stopping power and smoothness/linear feel I will put up with it.

I am happy with the R32 setup so far ( rotors are freaking heavy); but if I was to upgrade it would be either AP or stoptech trophies....

Imperfections in either the brake rotors or pads making gouge marks in my rotors

Here's a shot of my rear rotors. They both look like this. To quote my service manager "we looked at some other cars and they all look like this, so this looks like normal wear". Not buying it. My b6 passat has 180K miles and those rotors are super smooth.
