Freaky parts / Buildjournal Brembo BBK vs 996 DIY BBK for HPDE/track?

[Lavatoad]

Installed them last weekend. Running arc-8 18 x 9.5 et35 with 5mm spacer. It's pretty tight, but there is ~3mm of clearance at the tightest.

Yes for now because of the spacers you mention and the fact that the caliper used in the Freakyparts kit was designed for a 30 mm rotor currently has me going the 996 route. The latter I’ve read causes the pedal to soften according to some on the UK M3 site.

Been a little over a month, any updates from those that installed the freakyparts kit? I've had mine sitting in the closet since black friday, planning to install this weekend. Mostly street use, as I track a gutted e36 instead.

Also, anyone running this with zcp fronts? Read that spacers are required, ranging from 17mm - 20mm.

I can't comment on Hawk, and this is anecdotal evidence from other Ferodo parts, but it seems there are a fair number of Ferodo DS pads on backorder at the moment.

Essex is the only Ferodo distributor in the US ("officially") I believe, so if they're out of stock then the country is out of stock.

let me know what you hear. I was told I could do a "like exchange" and pay the difference if any but that they no longer have access to that pad. They did say they were trying to research new options but at the moment there is nothing. I do wonder if this is the beginning of the end for free replacement tack pads from FCP?

there is also this rennlist thread. In it FCP explicitly states that they will drop ship but when I questioned that and linked the thread I was told no.

interesting, I might go CSL rotors and keep the factory calipers as you can still get Hawk track pads from them. Less than a year ago FCP carried both the DTC-60/70 and DS11 pads for the 996 calipers.

Edit: Looking at FCP's site for other options, they list the DS2500 in both the F30 M-sport calipers and the M3 calipers, and show all Hawk racing pads for both models as backorder/no ETA.

Ok thanks SWRT - I thought maybe I could get away with it. Makes me think I should stick with CSL rotors, unless someone has calculated the increased bias ratio.

Reading on the UK site M3 cutters, some people complain of a longer brake pedal travel with this kit. Since these calipers were originally designed for a 30mm thick rotor, I thought the e90 rotors would help there as well. Or a bigger master cylinder maybe.

I just sent them an email asking what's going on there.

SRF has gone out of stock a couple of times, which made me assume they were going to drop it, but then it comes back...

FCP no longer caries the Ferodo DS1.11 which was the "race" pad for the 996 calipers. I bought a set in January with the install of my 996 retrofit only to find out I was one of the last folks able to do so. I'm bummed because I went with this kit strictly because of the cheap/replacements pads. There are better setups out there for track duty with cheaper pad options.

So it sounds like the Freaky Parts kit could work well. However now I’m starting to think about their E90 rotor kit using the 360mm x 30mm rotors. Anyone have thoughts on this kit? Same caliper so same piston area with respect to brake bias, but I don’t know if brake bias is effected by increasing rotor diameter only? Would love to have the larger and thicker rotor as a better heat sink.

For those that track with CSL rotors, do you still have overheating problems?

The 360mm rotor will give you a higher front brake bias vs using the same caliper on the smaller 345mm rotor.

Ferodo's shape # for D1001 is FCP3067 and Hawk calls theirs HB453. There is a thicker (16mm vs 14.7mm) D1001 that Ferodo makes called FCP1334 but I can't say for sure if that will fit easily. My guess is yes since it's only 1.3mm/pad difference on a caliper that can take a 30mm-wide rotor (E9X).

I could only find the DS2500 version of Ferodo's thicker D1001 on FCPEuro. The early 2010s TTRS uses a D1001-shaped front pad.

I can confirm the 8J TTRS 16mm thick pads fit with no issues with my Megane calipers. Running FCP3067 DS2500. 345mm new ZCP rotors.

Yes I’m looking for a cost effective solution, both initial and running costs. My main question is pros and cons over F/R 996. Like the pad shape into, did not realize that. I need to check if FCP carries that pad. I did not know there was a E90 rotor option, will look into that.

I also want to know if I can get by with this on the track. I’d rather not invest $1600 in this and then find I need to go full Stoptech down the line. I’ve talked to a couple of guys at the track with 996 setups and they’ve said it works. This kit should be similar.

agreed, a bit more rear bias is good. Especially when increasing suspension stiffness, you have less dive on the front axle, which equates to less unloading on the rear axle which allows the rear brakes carry more load.

I'd like to run 17" wheels with 996, but if I can source the pads through FCP, then I might consider other options and keep the 18's. The E90 M3 rotors with alpha calipers they offer is also interesting.

If you wanted to try one of the 6-pot caliper with E9X rotor kits, I'd go for their AMG one. That takes 1291/1405/1382 pad shapes which are pretty common. I don't know off the top of my head what those Alfa calipers would take. Probably easier to find those AMG calipers too, they have been on so many AMG cars with 360mm front rotors.

I thought about running E9X calipers when I bought mine but I was too lazy to do the math. Also it seems 345mm is enough for these cars at N/A power levels.
