If you've used the pads, then weren't happy, be disappointed. Don't pay too much attention to what's been said in that thread because for ever one person who said they've "overheated" them (which as I explained is a bit of a fallacy anyway), I can quote 20 threads or posts where people have been extremely happy with them.
Their biggest problem is (as some body else alluded to) is that that put them in the car, then hit the track straight away. You can get away with that with a dedicated track only pad, not not a street/track pad like the A1RM. Their other big problem is that most of them aren't comparing apples with apples, their comparing the A1RM to pads of far higher performance, when they should be comparing the QFM Comp pads to those.
The A1RM is a Ferodo 2500 equivalent, that is, a pad which is 100% streetable, but still capable of like track work, and that's exactly what it is:

If people need pads for high end track work, then they wouldn't be running a Ferodo DS2500 anyway, they'd run something like a 3000, which in the QFM range would be a Comp9. I'm certainly not phased about a few negative comments from skyline owners (who without Brembo's actually have relatively small brakes) who've hit the track on sticky rubber and wondered why a pad they could've put in their grandmothers 180B to drive to the shops on a zero degree morning didn't perform like a $600 race pad...
But, anything higher than A1RM is a compromise on the street (like any pad is, be it Ferodo DS3000, Project Mu's, etc) in that they have rotor wear and noise that is too high, and cold (emergency) bite that is too low. If people want to run those pads in their street car, that's fine, but we're certainly not going to recommend it.
So, I still 100% stand by the QFM pads, in that if people come to us asking for a street only pad, it's HPX. If people want a track pad, but say they still want to use the pads on the street, then it's the A1RM. And if people want a track only pad, or a pad that they're prepared to change to in their daily once they get to the track, then it's the Comp9.
Any negative feedback needs to be not of the product, but rather of
which product they chose. I personally run the A1RM in the rally car, and I can link another 50 forum posts of people who run the A1RM on the track, and love it. Don't beleive everything you read on the internet, and certainly don't be disappointed by it.
For reference Comp pads for the Supra are $179 per axle set for the 2/1 pots, and $229 per axle set for the 4/2 pots.
