I started a new thread obviously on my quest for a street/occasional track kit. One thing I'm annoyed by is how much most kits are overkill for my needs. The AP 372 is probably the least-silly of the not-Stoptech options at this point. One of my primary objectives for brakes up front is weight
The 35mm thick Stoptech is similarly absurd to the Alcon 36mm rotor. 380x36mm is the OEM thickness and almost the OEM diameter on 600+hp 4500lb 190mph AMG cars. Mine can't punish brakes like a 600hp AMG can, and it might do 190mph downhill with a tailwind and 10 miles of straight, and it weighs 3500lb and I don't need the rotors to last longer than the car at the expense of spinning weight that's relatively far away from the hub, and at the expense of wheel choice! Even the 355 on the front of my car has lasted foreeeeeever Tragic, truly

I'm about to upgrade to Essex's AP Racing RadiCal BBK and am curious if you guys are dealing directly with Essex or via a reseller?
I spoke with Essex already and they pointed me to "Apex Performance" in NC. They highly recommend them. Supposedly their biggest reseller in the country. Anyone know this outfit?

Cobalt XR1 (similar to CT XP20), XR2 (similar to CT XP12) I’m now 100% PFC for track/race pads since I first tried the 01 compound. I use PFC 11 on tracks with high speed braking zones (VIR) because the braking torque increases with temp (progressive) so you’re confident the pad’s always there at the end. Great modulation and release. Lower initial bite. PFC 13 has high initial bite, high torque, and progressive-digressive CoF (extremely high max CoF mid op temp, slightly progressive before peak & slightly digressive after peak). I use this on tracks with heavy/many braking events. PFC 39 has high initial bite, high torque and the flattest CoF vs temp curve. I use this when running super sticky tires. No experience with 331/332 but I’ve heard nothing but good things about them. I find the 332 CoF vs temp curve looks more like a performance street pad, not a track/race pad. I haven’t used Cobalt for years (since finding PFC) but their XR1 is similar to the PFC 05 (discontinued). 05 was one of my favorite brake pads on my track-prep e46 M3. XR2 is good for tires with higher TW ratings. |

I ran the PFC08s on my e46 and I did like them alot.. I ran several sets of Hawks and I just think they aren't that great. Good bite but they wear fast and once they wear down to 50% I feel they start to slack.. After doing some research, I'm thinking of the 331/332 set up.. I looked at the graph on the PFC website and I think they're a great pad based off the data they provide and they're cheaper than Pagid, which is what I was thinking of going with initially.

AP compatible PFC sizing is 7790.

Also, the CP9449 caliper uses the PFC 7768 pad which can be made from the PFC 7745 pad. The 7768 pad shape is identical to the 7767 (Ferodo frp216) pad shape except for the pad inner radius which is larger on the 7768. So the IR of the 7767 pad is increased to create the 7768 pad.

Good question. The AP sizes are so standard I’ve never seen something from PFC that wasn’t available. Cursory glance the 7745 and 7768 shapes look available in 332. But def worth checking

Radicals and BMW GT3 prior gen use the PFC 7767 so it’s offered in a lot of different compounds. I personally haven’t used the 331/332 compounds but I included it because I’ve heard good things from friends that have used it.

FWIW I run/manage three spec E46 race cars, all of which run the 331/332 compounds. One of our drivers is a consistent podium placer and nobody has any issues with the pads. I believe most of the field runs the same pads as well.

I’m not surprised. That’s why I included the 331/332 combination in my list. I could have easily left it off because I’ve never used it but like I said I’ve heard good things from people who have used it. I may try it one day but I have no issues with my pad choices.

Where did you see the 332 in a 7768 size? I looked a while back but could only find an 01. Would like the try the 331/332 combo.

I'm more than likely doing the 331/332 pads..
I'm only running the 9668 up front with stock rear calipers. They make the 332 for stock calipers and are pretty cheap.. $220 from BW.

I'm getting ready to pull the trigger on a front BBK finally. The Alcon kit has a warning not to use their kit if you regularly drive on the street due to deletion of the dust seals. The AP kit also apparently doesn't have dust seals, but the Essex website doesn't carry the same type of warning (they simply mention all aftermarket BBK's are labeled for offroad use, but that the components that must be DOT compliant are).
I drive 4-5k street miles per year in this car, is there anything I really need to be worried about as it relates to reliability? I'm not asking about pads not operating as well when cold; I'm asking about potential damage to the kit. |
