G-Loc is the new brake pad company started by the founders of Carbotech and these pads feel very similar to Carbotechs. The GPW7812-R10 track pad is for the Wilwood Dynapro front caliper, but not the 6-pot calipers I now have. The total thickness of these pads is 12mm and the pin holes are 3.25" apart. Retail price is $164 on the G-Loc site but you can have them for $90 with free shipping anywhere in the lower 48. I can't be 100% sure exactly which model Wilwood calpers these pads fit so please do a visual check before ordering to see they match the pads you use. Thank you for considering.
