Akebonos, with early spec pads, would fade very badly on track. Pads got hot too quickly and boiled the fluid.Are you confirming per your experience for track use or street? The issues came from lapping sessions on tracks. Drags or street pulls don't count since won't overheat these brakes much. This is my biggest worry still, even though I will immed swap out for track pads, ATE or Motul fluids, and braided lines.
Get track appropriate pads and upgrade your brake fluid, Akebonos should be fine on track, the calipers themselves do not suffer from any design shortcomings.
If you're hard enough on track with most cars, a brake system upgrade may be necessary anyway.
