NiMi:
I placed a link from our SRT brake research thread
HERE to this page. Thank you for taking the plunge to buy these DBA5000 rings. We have waited a long time, and done a lot of research, to find a reasonable price/source for these 6 piston Brembo rotors. You-da-man NiMi, you're the first one that I know of that has done this. So glad that these were a simple bolt on and that you were able to save a small fortune by buying them. You have proved that they are indeed compatible with our factory rotor center hubs (hats) and simply bolt on.
Found some info on another forum about these same rings that you just installed here:
CLICKY They were confused about the torque required for the bolts, but there was some interesting data there.
I contacted Powerstop about a 2 weeks ago and asked them if they intended to sell just the outer rings of these two piece rotors, like the ones you just installed. I spoke to them about this matter last fall, and they said they might consider it. Anyway, they told me that as of this time, they do not intend to do so. Therefore if we want to save money by just buying the outer ring, DBA is our only source, at least for now. I was talking to DBA awhile back about their patented unidirectional "Kangaroo Paw" rotor vent technology. They have some great pictures and explanations here:

Let us know how they work out sir.
