Brake discs OEM Toyota or OEM Volkswagen

The only thing I have done to it before the most recent work was to change out the rotors and pads.

Stock rotors are cheap and effective anything bigger is just for show.

GTI Clubsport rotors drop 2.2lbs per side at the front

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.

Mine are 288 fronts (yeah, I measured) and combined with the pitiful rears the whole systems is not (as I've read many times) "sufficient for daily driving". Too many times I've worried I won't stop in time. Too many times I've come down an average hill with definite fade that made me worry should an animal dart out in front of me. I want something akin to my GTI's brakes. Not something that will stop a freight train but just something I know will stop. And stop firm every time. Definitely OEM . I'd rather not have red but whatever I have, it will have to match front/rear. After reading the limited information I can find across multiple forums, nothing has mentioned swapping the front TDI brakes (if they are actually 310mm) over to a 2.5l. It would seem that if the caliper is the same 2.5 to TDI, all you would really need is the rotor and the TDI carrier, correct? Regarding the rears, nothing seems available straight off the OEM shelf, except GTI, correct? Any non-red options there?

This problem started after I changed the rear VW brakes rotors and rear VW pads and changed all four wheels with remanufactured VW Phaeton wheels.

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.

I looked at the brakes on our Tiguan, and it has one disc that is notably scored, same way. We just crossed 2k miles.

The rear brakes will be an absolute nightmare. There is not a lot of room. As far as I am aware, MK6/MKV R/R32 brakes are the same, so... prepare yourself for a miserable time doing the rear rotors. The rear pads are fine. The rotors suck ass.
