Consolidated Macan Brembo upgrade thread (READ FIRST POST)

Fastivus was a great test for these calipers. 360 miles round trip; 120 miles on track. My dad also drove my GSW4Mo and our groups ran back to back. The car was essentially on track for 3 50 minute sessions. The only weight we removed from my wagon was the spare tire. With two adults and a full tank of fuel we were ~3600lbs. We ran the R888Rs and Neuspeed RSe05s from my Golf for this event.

Right off the bat let me say these calipers are phenomenal! The OEM Macan shaped EBC YellowStuff used almost every mm of the Mk5/6R rotor surface. We experienced no fade and the brakes were consistent every lap. While I could feel the dead spot in the pedal after long straights, my dad could not. If I tapped the pedal before braking it was perfect. If I didn't the brake application was consistent after the first ~1/4" of travel. I do not believe RPVs are the answer. I do have a GTI/R master cylinder sitting on the shelf so maybe I'll give that a shot. I'm definitely excited to try these with BlueStuff next!

You really need to pair these calipers with 310x22 rears to get the most out of them on track. The extra stability and cooling are essential; especially on longer sessions.

Right on...wagon time! The wagons are heavy and larger brakes are key. Dig your 5-spoke wheels. Folks bust on EBC Yellows but I ran them with no drama include tracking it.

Anyone had to install these calipers with shims on the carrier bolts to center the caliper on the rotor? I'm installing mine on the recommended Zimmerman 345mm rotors on my GTI and the caliper is touching the rotor on the outside face without even torquing down the carrier bolts yet that would pull them closer into the rotor. Rotor screw is tightened up and I know it is centered as I installed a stud/nut kit at the same time.

I know other BBKs have shims for centering, I may just get some washers to make sure I don't have any clearance issues out of the gate. Everything else is sitting flush so I was kinda surprised that this is happening. If it matters, I'm using the calipers so the bleed valves face upwards as I see in the pictures in this thread.

I'm not aware of anyone that has required shims.

Strange ok, what kind of gap do you have between your caliper and the rotor on the outside face? Assume its 1-2mm but not like paper thin, need to figure out why this is aligning weird.

Edit: Nevermind, figured it out. My stud/nut setup isn't perfect so just had to give the rotor more push than normal, all seems good now thanks.

No, you screwed something up. There might be some slight runout (that should be corrected) on used rotors but that sounds wrong.

Thanks I updated my first post and good now. I installed a Racingline stud/nut conversion at the same time and the rotor got caught on one so I hadn't pushed the rotor all the way onto the hub. Loosened the rotor screw and repositioned it and now everything is fine, panicked a bit but all is good.

For now I'm just using some Z26 street pads and appears to be 1mm on each side unswept with the 345mm Zimmermans. For track I got Raybestos ST-43s that I probably won't be able to use for a month or two, still need to bleed the crap out of these. Thanks folks for the quick replies.

Don't used RBF660, it needs to be bled frequently, like between run groups frequent. Stick to RBF600.

?? News to me, been running 660 for two years with no issues. What is the problem with it?
I'm sure he'll just reply saying you must not go to the track enough to understand.

But for real, 660 just has a slightly lower wet boiling point than 600. Still better than a lot of other options on the market. Bleeding between run groups, lol.

Here in swamp ass Florida, it seems that it's absorbing water. It's not just me, all the guys I track with here have had similar issues. I've moved back to 600 and no more issues.

Keep your BS out of this thread.

Interesting. Well I’ve heard that brake fluids with higher boiling points tend to absorb more water so makes sense that in humid Florida that could be a big issue. I’m in California where it straight up hasn’t rained in six months so may have less of an issue here. I would run SRF but that fluid doesn’t seem to mesh well with our calipers, and I’ve heard RBF600 boils fairly quickly under track use, so that’s why I use 660. Will hope for continued no issues.

I’m at 13 track days since last June, all with these brakes & RBF660, so they’ve had a solid test.

Noticed you were in Norcal, so yeah, no 90% humidity issues. I grew up in SF, still have family out in the area, it's beautiful city. We used to skateboard down the hills, and hold onto the bumper of busses to pull us back up. Lucky I made it out of childhood.

Floriderp weather is not kind to tracked cars. Time trial over the weekend, my friends 19 Miata with 660 completely foot to the floor boiled it.

My buddy has 2 of the factory TCA Civics that he's been endurance racing, and the heat is killing transmissions left and right. He swapped back to 600 for similar issues with his brake. Same with a other buddies TT1 prepped C6 Z06 Corvette.
