Thanks, I have been bugging some folks via email
I am starting to think something with a wide temp range could carry me through getting some temperature data. Like a DTC-30, HT-10 or XP8. What I am thinking about is that the rears shouldn't get as hot, so I might not get a 'real' track pad up to temp. But as I have vented rotors on the front and the rears are solid do them end up the same temp-wise...?
The other side of the argument being getting a 900F pad and ending up with 1200F temps on the rear would be less than ideal. In the 900F range on the r50 I liked the ULT so would probably get those if 900F level pads is the right way to go.
Don't really know about the high temp rear pads, I do like the polys on the cars I have tried them on but nothing to fit oem rears...
Anyone have thoughts between XP8, HT-10, DTC-30, etc for the rear?
Don't how I missed this in my search:

But looks like nothing concrete was decided, though I can added RS-4 to the list to think about... lol -

As Ben suggests, a lot of this varies based on driving / braking style, track, conditions, etc. What works for one person may suck for another.
That said - the AX6 and XP8 are very different pads.
AX6- huge amount of bite, hot or cold, like throwing out a boat anchor. Which is great for autocross (when they're more likely to be cold than hot) and for mountain twisties (ditto). But they do have good heat tolerance - I've done crazy sub-16 minute runs on the Dragon and boiled fresh fluid... but not overheated the AX6 pads.
Downsides of these pads - they are CRAZY noisy (like a subway train braking) and they wear much quicker than the bobcats. Fine for how I use them, but would be too loud and too short lived for daily driver pads. And super dusty.
XP8- need to warm up to really bite. They're not "slick" when cold, but you definitely have noticeably less bite when cold than when hot. Probably more total heat tolerance than the AX6. Mine are probably a little less noisy than the AX6, but still noisy. Balance well with my XP12's on the front (with R56 front calipers).
I run Bobcats daily, put on the AX6's when I'm headed to the mountains for a weekend or a crazy day run, and put on the XP8/12's when headed to the track. The rears are more of a pain than the fronts... but I've gotten used to it, and have learned to swap the rears pretty quickly. -

Run XP8s all the time on the rear and change out the fronts for track... How you brake, when you brake, how long you brake and when and how you come off the brakes are things to be considered....and one set up might not be best at all tracks...same with corners and straights.
Guess what I'm trying to say is that brake choice is a compromise. Try some different combos and see what compromise fits your driving abilities and your cars performance envelope...
Good luck and enjoy the ride!!
