@NorthstarMS ENDLESS uses a mechanical retention plate, it's made of a soft mild steel that is spot welded to the backing plate. So it's a mechanical retention system, not adhesive (glue).
I've had two different sets of Pagids totally delaminate on a Nissan GTR track car. Both RS29 and RSL1, a racing endurance pad. In both OEM and AP Calipers. They were bedded in properly and brought up to temperature and cooled carefully each session. Pagid simply say "They got too hot on track..." So it is 100% possible to delaminate the Pagid pads... Re fluids, I use Castrol SRF which has never suffered boiling or compressibility at high temps, but moreover even the high temperature seals that AP supply need immediate replacement after each exceedence of 220 degrees C (430 degrees Fahrenheit). So it seems a bit pointless having a fluid which can go so high if the caliper needs a strip after each day on track to replace seals...
Now, I'm not sure on type of racing you're doing, but my first thought is to put you on a sprint race pad (RST series). This tends to work on the heavier high horsepower cars like zl1's gt350, hellcats, etc etc. The endurance pads you used are not going to be happy with consistent high heat as they are not designed for that and will fall part after some time. If you want more info and options give me or marc a call.
I use Pagid brand on my 2006 4.2 v8 Jaguar sovereign x350 model, they really are fantastic breaks.

This year endless had no change brake pad during 24 hour race w/AMG gt4 in Fujispeedway.
Does endless have any markings/logos on the pads themselves ?

Please let me know your opinion on running Endless pads on a GTR R35 with an Alpha 9 conversion?
does endless make a pad for pad shape 7416 a combo pad track and some street .?
pagid rst3 or endless ms35?
Why run anything else than the best brake fluid. Castrol SRF.
