I am running 15/16 on track.
First, you can use better brake pads than Pagid Blue. For track, I am using Raybestos ST-43, a lot better than Pagid Blue, but you can not use it on the street. I am changing the pad on track pit, anyway, I am changing the tire wheel at the same time.
In regards of the heat itself. You need more cooling, or more weight on the disc. I updated my disc with Alcon rotor DV295/28/53-12/178L/R on front. I build my-self the hat, if you want the drawing, PM me. The disc is bigger in diameter and in thickness. To compensate the bigger OD, very simple, just need shim to fit the caliper. For the thickness, just need to build small spacer to enlarge the caliper, with aluminum sheet .080. This set-up fits very close to my SSR wheel.
For the rear, I installed Alcon DV295/25/53-12/178L/R, reduced OD to suit the original OD. I also build the hat.
With that set-up, no trouble anymore, running with a supercharged engine. The first year with stock engine, I burned 3 set of pad, stock, EBC red (very bad stuff), and the Pagid Blue. plus, I cracked the rotor. I blow also the ABS unit.
