To be fair, the Supertech seat (shim) is "designed" around the dual spring configuration.

completely agree... along with their guides for dual springs, and the seals for dual springs.

The complete kit is part of the reason I'm not a huge fan.

With that said, "complete kit", I called Ferria (not Supertech) and spoke to them about their "kit" (single spring and retainer - uses OEM spring seats). I called BECAUSE their single spring uses the stock seat. I got an interesting education.

Although the OEM spring, seat, and retainer all fit together nicely, they don't "lock" together. This absence of locking together allows each part to have different frequencies/harmonics - allowing higher wear. In an engine turning 8000+ rpm for 95% of its life, this is a big deal.

The locking together typically means there is an interference fit, as an example for those who have used Toda springs, they tend to snap onto(into) the OEM spring seat - locking the seat onto the spring. I'd be willing to bet(a nickel), that the Toda retainers also lock onto their springs.

The big but....... for engines that don't turn 8000+ rpm for 95% of their life... how important is it?? Toyota didn't think it necessary for regular use.... but what is "regular" use????
