Those look very similar to the Wilwood UL32, which are $5 more.
There have been some comments about the practical differences between UL, HD and GT rotors, even in this thread I believe.
The UL are a lot cheaper, but can the Dynapro pads work with a "far side id" of 8.34 (1.705" vs 1.94" radius and of course the difference in heat sink mass).
The pad #7816 seems to have a 1.66" radius (ruler on the monitor) so the skinnier rotors might work after all?
The Wilwood selection in 11.75x0.81" with 8x7" bolt pattern
GT36 11.75x.81” far side id 7.87”
HD36 11.75x.81” far side id 7.87”
SRP 11.75x.81” far side id 8.34”
UL32 11.75x.81” far side id 8.34”
ULHP32 11.75x.81” far side id 8.34”
No revolutionary news... But I'm bored at work and might have use for the knowledge someday.
