Onto Second Set of StopTech 380 mm Friction Rings

[rzm3]

After three sets of front pads, it was time to replace the friction rings. Pretty straightforward installation. About 20 min each corner.

Old ring.



Old ring vs. new ring.




All drive pins need to be replaced, which came with each order of new friction ring.



Note orientation of the belleville washers.




One drop of Loctite for each pin. (came with the rings too)



All done! Ready for more track time.

"Friction Ring"??
R u serious? ... what happened to "rotor" or "disc"?

Looks like you've put some hard miles on those rotors

Yep, that's what they are called. I'm running the PFC BBK and they also refer to them as "friction rings".

Just finished my last track day of the season yesterday and it looks like I'm ready for my third set of pads on my StopTech ST60/ST40 setup. Should I expect to replace my front rotors after the new pad set is done, or is there a certain remaining rotor thickness you look for?

I suppose StopTech calls them 'ring' because you reuse the aluminum hats, which reduces the cost of replacement

The minimum rotor thickness is embossed on the outer edge of each disc. You should base your decision on the actual thickness measurement.

i thought they were always called friction rings, even the Brembo ones..

btw what was the thickness before you replaced it?

Just ordered new front rotors for my AP kit. I feel good about getting 2+seasons (probably 25 track days) out of these.

StopTech allows for 2 mm wear for most of its BBK rings.

Alcon, AP and Brembo are the same way - you just replace the "rotor ring" and re-use the hats.
