Feeler: Girodisc 2-piece floating rotors for E46 M3

[QuickM3]

Great, added you to the list. I'm hoping we can run standard pads (either with stock or Porsche calipers), but that D738 shape gives us a potential fallback.



Nice! Are you running stock rear calipers or Porsche calipers?



That's unfortunate about the PFC rotors, their parts are quality but sometimes scarce. What rear calipers are you running?



Ok, I understand now. Yeah, we'll probably stick with a standard slotting pattern to keep it simple and costs down.

I am running stock rear calipers. I have been looking at upgrading to porsche but will cross that bridge when its time.

List of interested people (carrying over from the 996 caliper thread), and I included whether people indicated if they have the Porsche calipers so they could run the shorter annulus pad.

Fronts + rears:

1. r4dr (Porsche rears)
2. SWRT_M3 (Porsche rears)
3. M3Giovan (Brembo retrofit kit, Porsche rears?)
4. terra
5. zivagolee (Porsche rears)
6. QuickM3 (stock rear caliper)

Rears only:

1. pawa_k2001 (Porsche rears)
2. sc_tr0jan_m3
3. elbert (Porsche rears)
4. SQ13 (Porsche rears)
5. Sharocks (stock rear caliper)
6. slavik1988 (Porsche rears)

I have Megane RS -Front (@buildjournal) & 996 rears.

Nice! I have Megane RS fronts waiting to go on as well.

Quick update, OEM rear rotors are here for measurement + mocking up. Hopefully I'll have another update soon.

[SWRT_M3]

awesome! hope everything lines up

[elbert]

Any updates on these rotors?

[r4dr]

Nothing yet, sorry. There has been a massive wave of orders coming in over the past month, so all efforts are focused on getting caught up before we add more products to the lineup. This is up next for new products though. I think the interest just from this one thread put it on the radar.

[R717]

Very interested in both front and rears. I recently picked up an '06 ZCP that I will be doing some instructing and trackdays with. I'm looking for a slotted option - I'm not a fan of drilled rotors based off experience with my real race car.

[LSBNick]

So as a non-ZCP owner, what would I need to make the fronts work?

[r4dr]

Thanks for the interest guys. We're slowly catching up on this surge of orders, I'm hoping new applications are on the horizon.

Just the caliper carrier (OE BMW or I believe ECS has a cheaper option) and rotors, I believe.

r4dr Thanks for response!

ETA; Do you think this would be a 3+mo development to come to market?

[R717]

Anyone heard any updates on the girodiscs? I'm going to need new rotors soon and would rather go for these over another set of oems.

[r4dr]

They're still on the list, but we've been slammed with orders and, of course, COVID-related supply issues. My own car is waiting for a set of these to go with the Megane kit I have sitting in my garage, so they will get done at some point in the near future.

r4dr Any updates on this project?
