All. I've reverted them all back to stock.
No, it isn't. You need to grease the pistons with RRG.
What made you switch the OBD11 settings back?

Was at Fastivus also and unfortunately the Jefferson track is so short and the parking lot is small that it is tough to really let those brakes cool down but I circled the lot a few times after each session. Did you do anything like that to cool them down first or just park immediately after the session? Hot air trapped statically in the calipers/rotors especially in the Macans is bad news generally.And definitely open to suggestions on rotors - dust/heat shield def can get modified up![]()
definitely recommend girodisc or PFC if you can swing them. racingbrake, ecs, 034, and neuspeed also sell 2-piece rotors of more questionable origin.And definitely open to suggestions on rotors - dust/heat shield def can get modified up![]()
Minimal cool down to be honest, I did take the "long" way around back to my parking spot to let them cool some but clearly not enough...Was at Fastivus also and unfortunately the Jefferson track is so short and the parking lot is small that it is tough to really let those brakes cool down but I circled the lot a few times after each session.

I'm running the ECS 2-piece 345mm slotted rotors that have been solid with the Macans, I think the directional veining and 2-piece really does make a difference in cooling compared to blanks but maybe I'm in the minority. Install the RS3 plastic deflectors as those help a lot with getting forced air to the rotors. I've cut all my heat shields to the absolute minimum with tin snips to only protect the ABS components and the ball joints at each corner.
Completely losing brakes at 148mph.What made you switch the OBD11 settings back?
Completely losing brakes at 148mph.
Other people tracking with various brake kits has same issue after doing the OBD11 mods.Yikes!!!
You’ve been running these for awhile, interesting a problem would pop up now. Was there anything specific that made you determine it was the OBD11 mods, or just the most likely culprit?
I did the OBD11 mods too, so kind of rethinking them. I don’t track my car, so it never sees that kind of speed.

RRG is the right way to get the correct feel, not making changes to brake balance that we don't fully understand.
Still no issue with these settings on the street.
When I went back to stock OBD11 settings, the car rotated better under braking, too.
Yeah, I was thinking that as I typed that out.Interesting, so you also dialed back all the tweaks? May be worth updating the original post to highlight that

Proper way, remove them.whats the proper way to apply RRG, take piston out or no need?
Take it you've never had to clean the inside of a caliper that had rrg that dried up and caked all over the inside before...Jay is correct that it's best to remove them and lube, but I'd still use rrg, we have quantifiable data on the thread that it greatly reduces the piston retraction.
That's not the point though. Many motorsports teams use it to reduce piston retraction, it holds up well, and a member here tested and it reduced retraction by 50% on these calipers.Take it you've never had to clean the inside of a caliper that had rrg that dried up and caked all over the inside before...
