QFM HPX vs. Bendix Ultimate
...Ultimates are like a set of Ferodo generic pads!
In My Opinion - I have tried both on my VX Commodore:
I had Bendix Ultimates and I found them to be noisy, very very dusty and it liked to eat out my rotors, they pull-up was okayish but I found they didn't have enough "bite" for my liking.
The QFM HPX Pads - I had them fitted to new rotors as the old ones were chewed out and could not be machined further. I purchased standard rotors after the pads had been bedded in wow.. simply wow!
The pull up from them was so much better, and ABS kicked in much much quicker
hardly any dust and alot less noisy.
Still some squeaks here and there but all in all,
a much better improvement over the Ultimates.
