Anyone ever try these rotors?

I saw a post in C5z section where a member purchased J-Hooked 1 piece rotors from here and it caught my attention. Nothing was mentioned regarding track use or other...

The 66 pads have more pad area (footprint) than the 74 pads but 17mm material cpmpared to 20mm. Looking for best of both worlds for consumable savings, thicker (longer life) and larger footprint (more friction coefficient and likely help longevity). Does Wilwood offer a caliper kit that uses the 66 template with 20mm material that can be used with C6z oem/Centric or other blanks?
Been quite a while since I did the math but I believe the 6617 pad has more cubic area than both the 7420 and 7416 pads. By roughly 10% or so on the 20 and 20% or so over the 16.
Pad life is going to be determined by not only the cubic inches but the compound, heat and area of the pads. Assuming the same pad and use the added footprint should produce a longer life alone even if only slightly more cubic material is available.
As for the second part of that; its the same question I addressed in #33 / #34

Most of the pad volume is here http://wilwood.com/BrakePads/BrakePads.aspx
6617 is 5.2 cubic inches
7420 is 4.9 cubic inches
7416 is 3.8 cubic inches
stock front is a 731 which is 4.1 cubic inches which is my issue with running a 7416 in front.
stock rear is 732 which is 1.7 cubic inches which makes a 7420f/7416r setup seem reasonable as i could just move front pads to the rear and save some bucks on pad life.
