RacingBrake Sintered pads wear rates

[sharmut]

Anyone else try the RB sintered pads on their ACR-E with CCM? Read WERK's post in 2016, have not found anything more recent.

Purchased the 2016 ACR-E used with the RB pads installed, according to the previous owner the pads had 3 HPDE sessions. I put another 7 (20min) sessions @ Thunderhill Raceway, totaling 10 sessions. The lower control arm brake ducts were installed.
Below are images of the front pads at the end of the 10th session. While they seem to do what's claimed with regards to rotor oxidation, this pad wear rate seems excessive to me. Recall reading VENOMV post on the OE pads and getting 4 hard days out of the front pads.

Seems to be tapering on the outer pads from top to bottom. Did I overheat the pads leading to the tapering?

I reached out RB to get their thoughts, awaiting a response. In the meantime, I plan to pull the rotors to weigh them.

Have a new set of girodisc and raybestos pads on the shelf, if the wear rates on these sintered pads are 2 days @ $895/front axle.

That is why I have steel brakes on my ACR-E. :D

I have used racing brake sintered pads on an aftermarket ceramic brake system that i had installed on my GTR. I went through the pads in one track day. This may have been due to too much heat, but it makes for a very high track day cost.

What did you not like about the stock pads?

Nothing against the stock CCM pads, the car came with the sintered pads and thought the concept sounded interesting. Wanted to see for myself what they were all about, discovered not impressive in actual practice and hard to justify their cost.

Did hear back from RB after they reviewed images of the front rotor, they indicated my rotors are done and should be replace. My interpretation of their message is the pad wear is due to the rotor "cheese grater" condition. I found their comment interesting in that the point of the sintered pads was to refill the oxidation voids.
Below is the rotor image after using the sintered pads for 10 sessions and the OE pads installed for another 2 sessions. The voids in the image were previously filled in. Once the OE pads were used, the voids returned.

Guess it's time to mount the Girodisc.

I completely understand. What I do like about the CCM package are the calipers with the front a monoblock design. Shame they did not trim some material from the lower section of the caliper to give us more clearance to run 18" wheels.
If I were to order an ACR-E now, I would order with CCM and swap out the rotors to steel and reuse the calipers.

The previous owner of the car ran them for 3 light HPDE sessions. The hardest sessions were from 5th to 10th sessions. It seems our use rate is very close and not all that surprising.
