This brake system is ok for the street.
It just makes the original style system seem like a good street braking system.
When the car was original the brakes were horrible. After this change it was a good street car.
The original rotors would be the problem for the track.

I have to say this brake system at high speeds was every bit as good as the
sierra and wilwoods.
Under what conditions? I fully believe that what you say is true for normal and even aggressive street driving, and a single panic stop. But repeated heavy braking (track work) will overwhelm any braking system that relies on solid rotors. Ken stated the facts there extremely accurately and succinctly, I believe.
Did you have contrary experience? That is, did you punish your brakes with maximum-effort stops for extended durations and suffer no degredation of performance, with your dual-rear-caliper setup?
I've never noticed any brake fade etc. on my Wilwood-equipped Pantera even after extended track sessions (45 minutes or longer sometimes). On my GT350 clone, I did have some issues which were rectified by installing a very professional cooling ducting system. It takes ram air from the nose and routes it through three-inch hose directly to fixtures bolted to the spindles, which blow half the air onto the inside surface of the rotor, and the other half into the center of the hat, where it is then radiated outwards through the cooling vanes. That completely eliminated anything resembling brake fade, even under severe punishment.
Cory Gehling (Collector's Choice) sells (or at least sold) a pair of bolt-on widgets which attached to the inside of the Pantera spindles. They weren't set up for hoses; instead, they acted like cupped hands to trap the air going buy and duct it onto the rotors. I don't know how well they worked, if at all, nor do I know if he still sells them. I contemplated buying them for myself, but my own experience indicated they weren't necessary, at least on my car. Perhaps when I start running slicks, the increased energy directed at the brakes (made possible by the much greater traction available under braking) may cause me to revisit that.
