Which balancer?

And FWIW: As I understand SFI certification, the Mfr submits some samples to undergo testing for a given SFI spec. Once the samples pass, then the cert is issued. As far as I know, there are not any follow-up checks with SFI certs; it is up to the mfr to maintain the quality.

FIA is different; once passed, then each mfr is subject to occasional checks on the mfg process and product. If they don't maintain quality, the FIA cert gets pulled. One racing seat mfr got all of their FIA certs pulled about 10 years ago due to this.

So, as I understand things (and please correct me if wrong), SFI parts quality can potentially vary over the life of the product with no real process in place to catch it. Basically, the design is SFI certified, but there is no running quality check process outside of the mfr.

My experience with the Chinese in other fields is that they will pass the test, and then do what they darned well please over the long term if no one is regularly holding their feet to the fire to maintain a standard. So how good any SFI part made in China is going to really be, IDK.
