I have been hunting around trying to find the best pads for my SRT with low dust but still with good Bite/Friction/and fade resistance and after getting totally lost as to the best solution I wrote to www.zeckhausen.com
and got the best support I have ever had from David Zeckhausen himself where he expained the different pads and the effects of them rating them 1 to 5 based on the pad.
I have never had anyone put themselves out there to help as much as this so i am passing it on and hope it helps others but a big thank you to
David Zeckhausen for taking the time and making the effort to help me.

The recommendation depends on how you plan to use the Jeep. If you plan to take her out on the race track, that rules out all choices except Porterfield R4-S. Otherwise, it comes down to a combination of performance characteristics - bite, friction level, fade resistance, noise, rotor wear, and dust.
Since you mentioned low dust, let me sort the choices for you in terms of cleanliness. (3, 5, 1, 2, 4)
Now let's sort by bite and friction: (4, 2, 1 tied with 5, 3)
Fade resistance: (4, 2, 1 tied with 5, 3)
So you can see, the cleanest pad (Hawk Ceramic) is also the lowest performance pad.
Noise, sorted by quietest first: (5, 1, 2, 3, 4)
Note: all of these pads are low noise, but I've sorted in order of the least likely pad to squeak at low speed, light pedal pressure. Rear calipers on the Jeep SRT8 are notorious for generating low speed squeal, even with stock pads. So it's possible any of these might make occasional noise in the rear.
