Honestly, I've looked lol.

Unless you get one of the custom "made-to-order" companies like RacingBrake, you're not going to have much luck. I only ended up with mine because the BBK I bought came with them, otherwise I never intended on changing them.

FWIW the M2**iR uses factory rear rotors/calipers with a PFC front BBK. Once you install the bigger fronts, dial the brake bias forward and you'll see how little the rear is actually doing.

IIRC, you have a sweet BBK up front, already? Did you update the brake bias already? I only ask because I didn't at first, to see the difference, and it was night/day.

haha yea man i was trying to avoid those made to order companies. And yea i already have the StopTech Trophy BBK up front and adjusted the bias at the time of install and your right the rears dont do a whole lot lmao. Maybe im getting to that point where im buying shit just to do it lmao.

Search for "Pilenga" rotors. Italian company that is the OEM supplier for these 2 piece rotors. They sell rear and front 2 piece at almost half price compared to dealer. They come off the same assembly line.

Here's a US supplier of Pilenga rotors: https://www.partsgeek.com/catalog/20...?brand=pilenga

Pilengas are not, however, two-piece rotors in the conventional sense of the term. That is because the hats cannot be reused. This Essex Parts M2 Competition two-piece rear rotor is an example of what a two-piece rotor looks like, with a reusable hat bolted to a replaceable ring:

Is there any advantage to a reusable hub? I'd be concerned about the assembly process of the new rotor to a used hub and whether it's as robust as a factory made set like the Pilengas.

Thank you for the Pilenga link btw. With the factory like aluminum hubs, those look like the replacement rotors I would go for when it comes time to replace.

Well, the rotor rings are cheaper than they would be if they came with a rotor hat permanently attached, so there's that.

Two-piece rotors are much more a race part than they are a street part. I'm not sure I'd run one on the street if I used the car as a DD. I had them on a race car and used a shop to change the rings out when they were used up.

About two-thirds of the way down in the following link you can read about how a two-piece rotor works. The entire page is well worth reading if performance braking systems are of interest to you.

^^ FYI I DD mine for 6 months/year with two piece floating configuration. It's super easy to swap rings, you just need confidence in yourself lol. The first time I did it, I took my sweet time on a bench with hand tools.

You can run a two piece "fixed" setup, which reduces all/any noise associated to a floating design. Mine don't make noise at all, like others report..

Yea, I mean, if the iR doesn't "need" them for endurance racing, I think you're good. The OE rotors are much better than they're given credit for. It's technically a two-piece steel/aluminum riveted design.

What I might suggest is a pad out back that bites hard, like XP10's, can help balance things out if you're "nose diving" a bit too much up front.

I had been driving a track prepped TTRS with a team of colleagues with stock brakes PFC-08 pads up front (endurance) and the XP10's in the rear, and after 4 combinations, that's what felt best on course for lengthy track sessions. It was nose diving really bad without the harder biting pads out back, it made a substantial difference. BTW, those rear TTRS calipers are single piston Golf R calipers, casted and all, the two piston Brembo's should do better for sure..

lmaoo i DD'd mine full race seats and all for like 6 months (recently got a jetta for the daily lmao) haha yea i know man, ive done just about everything on my car by myself lmaoo, and yea i feel that for sure, the best feeling combo for me has always been the ferodo DS2500 all around honestly (used to have StopTech SR34's up front and SR33's in the rear)
