Here's where I saw they were 32mm, but it looks like just this vendor.

Its a 2 piece. Oem are 30. I wonder how those fit using oem mk6 R calipers. Width wise

2mm shouldn't make any difference at all with new pads. Calipers are all self adjusting, or your brakes would go to sh*t every time you wore your pads down 1mm each. The only time 2mm in width matters is towards the end of the very end of pad wear where you might push pistons out too far... but 1mm each side is NOT going to make a difference unless you do something stupid like take your pads down to bare metal.

Not to mention the Macan brake rotors are 30mm, as are the Q5s.

Hmmmmm, I could have sworn mk6 R were 32mm wide. I uses Zimmerman. When I swapped in the new rotors, everything firmed up.
I had the exact experience moving from the MK7R to MK6R Zimmerman rotors and it was noticable before bleeding.

I'm still not a big fan of the amount of pad deposits left by the Powerstop Z23 pads paired with the coated Zimmerman rotors. It's was enough to feel until I deburred the pads (no I do not condone reusing pads 😅🙃)

The Centric 104/StopTech 308 are going on next. They have been great in the past and it's just $30 for science!

I get what you're saying, but these cars have abs, brake boost, and tons of weird stuffi going on with the brake system.

You have two people that swapped rotors and had everything firm up. Why? I don't know.

Swapping rotors requires removing the calipers which means you're moving things around. Very possible these are prone to bubbles being trapped somewhere in the caliper, and by changing the angle of the caliper you freed the bubble, which allowed it to travel back to the reservoir.

There's a lot of stuff going on but there's no way that width is going to make a difference except the first 5-10 times you pump the pedal until the calipers adjust to the rotor thickness.

Totally possible.

All I know is there were spongy, I swappes rotors, sponginess went away. Maybe even just the act of speaking the pistons got somw trapped air out of there.

I think I figured out why the brakes are so weird feeling. Even after I got them to firm up, they never really felt like I'm used to in my old STI or 911. I bought OBD11 to make some changes for track and had an ah ha moment.

The last change to make was for hydraulic brake assist, but I couldn't get it to work in OBD11 because I didn't have the correct security code. Took a couple of days to find it, but in the meantime, I drove around with the other changes and brakes felt the same. I finally found the code and deactivated Hydraulic brake assistance in the 03 module and they brakes actually work like a normal car now. Holy cow, night and day difference.

Here are some of the changes, but hydraulic brake assist is the only one your notice in everyday driving.


03 braking module security code 25757 worked for straight ahead brake stabilization. Turned it off and it'll allow trail braking into a corner without the abs fighting you.
03 braking module security code11966 worked for hydraulic brake assist. Removes the computer controlled brake boost that smooths out your braking and boosts braking pressure in panic stops. Gives you 100% control of brake pressure. Pedal felt amazing after turning off.
32 locking electronic module security code 20103 worked for Expanded differential locking. Set to increase traction and it will increase the pressure to the VAQ and lock the diff quicker and with more force. It might increase pump noise, but that's about it.

These will work on any PP whether you have Brembos or the stock PP brakes.

Enjoy.

There's some more information on this thread it seems. Going to try this tonight and see what differences each setting makes.

Thanks for this bit of info, just made the change on my car with the TTS brakes and drove around. Pedal feel is much improved, it has a more linear pedal feel just like the Brembo's I had on my old MK5.
