After using a test day for nothing but brake compound testing and related data analysis, I decided to switch from the Carbotech XP9's that I had been using to the Hawk DTC-70. The DTC's have much more initial bite either the Carbotechs and the Cobalt XR3's, but not nearly the levels of the Blues (thank god). I didn't test the Raybestos.
That lower initial bite on the CT and Cobalt compounds lead to a longer pedal, higher necessary pedal pressure and more frequent rear lockup (even with my adjustable prop valve for the rear) in some braking zones that really unweight the rear of my CRX (like T5 at Summit Point). Since you're carrying more weight in the rear it might not be an issue.
I also did some testing w/ crappy AutoZone pads and Cobalt XR5 in the rear and could never really dial out enough bite from the rear via the prop valve with the Cobalts.
BTW--we decided to go with the DTC-70's vs. the DTC-60's after my teammate had experienced some issues getting through a race w/ the 60's. They apparently don't hold up to the extended periods of high heat (let's just say that the CRX is a bit challenged when it comes to front brake cooling...even w/ good ducting).
