Performance Friction Direct Drive Rotors

Has anyone tried these for the M coupe? http://store.bimmerworld.com/perform...tors-p608.aspx

Are they a direct swap for our rotors?

Update. Just called. They will not. So, the only options for our cars is to go BBK. No intermediate option before that. Sigh.

arhh that sucks imo.... we need more options for our brakes, i really dont want to have to spend 3500 GBP on stoptech or AP, i wish we had an option for GTR like AP j hooks, my thinking is a Real nice quality disc, uprated pads, braided lines, uprated brake fluid... this should do really imo!

Hack,

What are those?

Did Bimmerworld give you a REASON that they wouldn't fit? Because they also told us that their E36 Shim kit wouldn't fit either!

The reason given was that the brakes are direct replacement for the e46 m4 (non competition package). 12.x inch rotors. Since we have the competition packaged rotors (345mm), they're not direct replacement for our car or the zcp e46.

+1 on what those rotors are Hack.

Looks great. I assume you've liked the way they performed over the years?
1. Do you track it?
2. Still on the original discs?
3. What pads do you use in conjunction with them?

Sorry for so many questions...been looking for a good brake pad/disc combo for next year. Thanks.

Those rotors at racingbrakes are expensive! Almost 400 per rotor. Are there any cheaper alternatives? Definitely not looking forward to when I need my brakes changed.

1: I've had on average about 12 track days and 3-4 auto-crosses per year on these rotors for the last 4 years. Car's got ~30,000 on it, with about 28,000 miles spent on these rotors and if I had to guess? About 4,000 of those miles spent on the track.

2. Yes. I expect another 1-1.5 years on the original rotors before I need to change them. Although I thought that about a year ago. I wouldn't be surprised if I get more than 5 years of abuse, er, use out of it.

3. Cobalt XR3s for the last 3 year, Hawk DTC-60s this year, and RacingBrake ET500 pads for street and autocross use.

You talking about the Performance Friction Direct Drive rotors? Yeah. They are BANK. But they are bank for a reason. True 2 piece floating rotors will do more for your braking system's cooling and longevity than any so-called "big brake kits" ever will. In fact, MY criteria for any brake upgrade involves 2 piece floating rotors, and the Direct Drives are about as good as they come. The RacingBrake rotors I have are just as good.

But if you think about it. The replacement rotors for the MZ4 Coupe and Roadster are $290 ea for the front and $225 ea for the rear. For a little bit more, you get a replaceable rotor ring, which means the NEXT time you need to switch rotors they'll be significantly cheaper. And they perform better too. So for $20-40 more, and if I have to replace the rotor anyway? NO BRAINER.

Almost $400 per rotor, but the NEXT rotor change are around $150 ea (since you can keep the hub and just replace the rotor rings). BMW rotors are around $300 ea EVERY TIME since the floating pins are sandwiched between two castings.

And you're looking at suggested retail price I think. Any RacingBrake distributor will likely be able to get these rotors significantly cheaper than advertised.

The zcp brake conversion kit for m3s had a price drop to about $1000. It comes with carriers and I was thinkig about picking that kit up and sell the carriers afterward assuming the zcp m3 brakes are the same as ours

I think that'd be a decent investment if you could secure the sale and/or fitment of the carriers to an E46 M3. I'm pretty sure fitment is exactly the same though.


and Hack, good point about the next time around. I'm surprised these last that long. Jesus.

So Racing Brake only offer fronts? No rears?

They have rears. They're just not listed because they have the same problem as does Performance Friction. The way the fasteners are, if you use stock pad shape eventually the pads will grind into the rotor to hub fastener. Solution is to go with a shorter pad, but they decided not to offer that until they have a set of pads they can sell along with the rotors, and that hasn't happened yet.

But they have rear rotors. I test fitted a set and had to give it back due to the pad issues. If you call them you can actually order it if you acknowledge you understand that the OEM replacement pads are not compatible. I'm waiting for their new pad applications to be ready, since I've already got a set of Hawk DTC-60s in the OEM shape for the rear right now.

ah icicic. What pad would you suggest if I still want to be able to use them on the street? And if I only do weekend track days, but want performance when I do go to the track?
Or should I literally invest in track-only rotors and pads? They're pretty easy to swap anyhow, since no fluid flush is needed.

ZCP rotors are cheaper but I don't know if they are direct replacements. Anyone have any experience with the fitment? They are different part numbers tho too

Not sure if E46 M3 can take ZCP (CSL) rotors as an upgrade from stock non-ZCP. I'll ask some friends. Have plenty E46 M3 buddies =P

Well zcp rotors can fit reg m3s but need carriers. I was referring to if zcp rotors off an m3 fitting onto our z4 m

Couldnt you just use that special short PFC pad that is ment to work with the Directdrive rear rotor?

Anyone know if these will fit our cars? Thinking of purchasing a set but worried they might not fit.

You can use whatever pads you desire. For a while I was driving on the street on the DTC-60s on my last car on a daily basis. Not the prettiest sight thought, basically my boss will know when I pull into work every day about 1/2 hour after he did. The only problem is, you absolutely have to keep a very close eye on the pads since once they start rubbing the fasteners, you have to swap them out otherwise you'll ruin the rotors.

Making pad recommendations without knowing your actual driving style and skills is like trying to diagnose a rash sight unseen. I personally go with the most aggressive pads that don't fade given my speed. Back long long time ago before I had a powerful car, I used to get by with mid-range track pads like Carbotech XP Plus, Cool Carbon R/T, Porterfield R4S or Hawk HP Plus equivalent. Most of these, especially the Cool Carbon R/T, was suitable for street AND track (they're some-what civilized for the street...Or at least livable). But as time goes on and my skill and speed increased, some of these pads are inadequate for the heavier braking (and higher powered cars) and I've since moved on to Cobalt XR-3 and Hawk DTC-60s as my exclusive pads.

Don't forget, the OEM rotors on the MZ4 is already the best braking system BMW has made. It's even better than the brakes on the 135i. It's a true 2 piece floating rotor and it's far more effective at evacuating heat than most other BMW brake systems, and to be completely honest, if RB doesn't have their 2 piece offering, I'd probably be happy with the same OEM rotor replacement...

I don't know. You would assume so, but the problem is, you can't assume that the hat and fastener dimensions from PFC is identical to the RB rotors.

And I'm partial to Hawk pads...Not for performance reasons, I'm just brand loyal that way.
