Porsche Brembo 996 BBK conversion

[r4dr]

Any chance Girodisc will make a 2-piece floating rotor for the E46 M3, especially one that works with these Porsche calipers?

In 03/08/18 I asked and Mike said it would be $1000 per rotor since they would be considered "custom". Hopefully you can help bring the price down for us.

I'm interested as well.

Asked around, we can do fronts no problem. The policy is if we get 5 committed people, that's enough to design for the application. These would be direct plug and play for 345mm ZCP/CSL front rotors, so they would work with the OEM sliding calipers or any of the various Brembo kits (996, Megane, etc.).

Rears might get a little more challenging but we can look at those once the fronts are on their way. PM me if you guys (or anyone else) are interested and I'll give you my email plus make a thread on here. I'm not really active on FB so if you know of anyone else, the more the merrier.

These kits aren't genuine, they're cheap chinese parts that work. Porsche kits are extremely nice and machined very well. The quality of genuine kits is high but Porsche isn't really big saving money in production it seems. They outsource to VW for that but these are Porsche designed. I have ATE spring kit, which I think is the OE supplier of the kits and they're absolutely junk compared to original. I think it's one of the main factors in my brake noise. In this case, I'm going to swap for genuine parts which will ironically be ATE but a completely different product. Taxes are dumb but there are those rare times you get better stuff for paying them. Remember that these are also 911 parts off of $82,000 cars. Today that's $122,000. Cars depreciate, new parts don't. Why is an SMG pump STILL $3500?

I've used Centric or Performance Friction (probably same factory as Centric, different box lol) friction on Brembo calipers on Porsche, Shelby, etc. cars with no issue. RockAuto is fantastic.

I also went with rockauto for these kits. I was blown away at the prices for the genuine Porsche stuff!

What replacement hardware are most of you using? I'm asking about the pad retention spring clips and rods (part number 99635295901).
FCP is selling genuine Porsche for $66. I can find Centric and Raybestos for $5 or 6.
I realize that P-car tax can be steep, but 1000%?

selling a set of pads if anyone needs them.. just about brand new hawk pads.

Recently completed this conversion on my street car. Wanted to share that I used the ECSTuning rear brackets (CreationsMotorsports) and was able to pretty easily get the Shape "D737" larger pad to fit on the back of the rotor with some light trimming on a bench grinder. Also trimmed the backing plate to maintain that. Specifically using the Akebono EUR737 from FCP Euro.

The rears get interesting. PFC does the weird pad shape because the 1-piece rotor doesn't have enough room for the 2-piece hardware between the swept area and the hat. I think what might end up happening is that if we can get the fronts going and show a market case for the application, then we might be able to do some engineering to make a rear 2-piece rotor that doesn't require a different pad shape.

Yes, I was talking about the rears. I figured it will be tough to have both a parking brake and have enough room for the hardware for a 2 piece, especially with only a 328 mm rotor. I was hoping having the option of the shorter D738 pad would give enough room, but that still might be pushing it.

Absolutely. I can't comment on pricing since that's not my department, but it would definitely not be $2000/pair.

It seems like we have 3 people (including me) interested without much effort, I wonder if we can put a list together. We could have the rotors ready in a month or two, given that my car is here to test fit them.

I'm interested as well.

[r4dr]

Yes, I'm def interested, but a couple caveats:
- Similar pricing as the PFC Direct Drive rotors (~$430/complete rotor)
- Use commonly available brake pads without grinding/customizing, maybe using the D738 shape which is 5 mm shorter
- Keep parking brake functionality

I'm guessing you're talking about rears? I see Bimmerworld has 345mm fronts for $522/rotor and 325mm fronts for $475/rotor. We would likely only do 345mm fronts as that's a no-brainer upgrade even for cars with 325mm fronts and floating calipers.

I know we've done a Corvette application very recently where the rears had this same issue.

It's in the pipeline, especially since I own an E46M and would like to run it... if you're interested, email sales@girodisc.com and tell Mike lol!

What's a good street pad for a ralley? I'm not sure where to begin. Porsche makes pretty darn good pads but if I can get a better pad I will.
