Rotors

_Ryan_ · 04-04-2015, 02:56 AM

Gents (and token ladies),

For those not running a BBK on their 135i, which rotors are you using?
I am currently on BMWP rotors and am due to replace them.
The options I have found and am considering are:

BMWP
StopTech PowerSlot
Project Mu CRD

Those I am not considering are:

ECS
Zimmerman
BMW OEM
Centric blanks (StopTech slotted are peanuts more!)

What have I missed? Which have you run?

Car is used for: occasional track, frequent punishment in alpine regions, driven daily to work.

Centric blanks or OEM. Whatever I can get for cheap, but not cheap enough that I'm concerned about my life being in danger.

Slotted/cross-drilled rotors are a gimmick. Enjoy less stopping power, and ability to handle heat.

I have dba and If I were you I would consider them in the list to have. these brakes do really brake with hawk hp+. I have the t3 with the kangaroo paw ventilation and these things remain REALLY cool.

Being Australian DBA were the first place I checked with (via our resident brake experts) only to be told that they don't do rotors.

Do you have the part number of the DBA rotors? Were they listed for another car?

Ahhh, I was only looking at the 4000 series and higher. Thanks.

I'm using EBC rotors as the moment. It is dimpled and slotted, but no holes.

Where can I order the project Mu rotors? I'm not even sure they make CRD rotors for non Japanese cars.

I spoke to the AU wholesaler- they do. Also looking at whether we can do a group buy without upsetting their retailers. HC+ pads are great, but at a 4 week lead time and 850 AU per car, it might be worth doing a bulk buy...

Details of dealers are here- http://project-mu.com.au/en/

Where did you source the EBC rotors?

John_01 · 04-07-2015, 07:59 PM

I got the EBC rotors from ECS a few years ago when the exchange rate was good. If I am buying again I will enquire with brakesdirect.com.au . There are also many auto parts dealers that theoretically could order them.

EDIT: The EBC rotors I have now are GD sport with dimples and slots. They have done 7 track days and 15,000km on the road with Ferodo DS2500 pads. I think they would be better with only slots and no dimples because the dimples cause uneven wear on pads and rotors. If buying EBC rotors again, I will choose the USR slotted version instead. I think drilled rotors are an even worse idea.

BrokenVert · 04-07-2015, 08:49 PM

I put on stoptech slotted last fall and im a big fan. Autox season here is starting late, so I wont be able to talk about that yet.

But the brakes are very solid.

They only offered protex or something- I used to use brakesdirect/GSL with my JDM cars; good guys.

This gets better, current costs are captured below:

[pairs]
OEM blanks: $AUD250 to my door
P.Mu CRD: $AUD600 to my door
Protex: $AUD600 to my door (pass)
EBC - similar to CRD
ECS: ~$AUD1000 to my door
BMWP: ~$AUD1000 to my door

Does anyone have actual data to support the ECS/BMWP providing stopping distance and/or heat management benefits to justify the spend?

fe1rx or dcaron9999 or justpete or @[HP Autosport] ?
