In that photo, note how stock disk springs are barely visible. Entombed by shroud of metal. Compare to nearly naked yellow springs on aftermarket disk, just waiting to go sproing.

Honda improved the design (springs now in a tomb of metal. Not goin anywhere). They only sell improved version now.

Unfortunately, virtually all aftermarket disks are copies of original ap1 design, except often with lower quality materials (some better than others).

So all will buzz, all will fail from dropped spring well before they come close to wearing out (barely broken in).

For such a low volume car, not worth it for them to redesign and retool to copy improved design.

The AP1 design still had captive springs. IIRC, they had a dual captive spring.

The AP2/update disc has a single spring that appears to have slightly more preload.

OP, you can just buy a stock (genuine Honda) disc to fix your problem. Again, you *really* should also buy the factory bearing set and release bearing guide, as well as urea grease.

And you need to do an interlock bypass.

That is an unusually high number for those mods.
