One of our members in SOXC works for a metals company and knows metals and their applications pretty well. Through him we have spec'd a heavier duty bronze for the bushings and are also going to use a stainless steel sleeve to replace the ones Calmini supplies with the kit.

He assures me that if kept properly lubricated once installed, we may NEVER wear out these new ones. They will be ready in 3-4 weeks.

Once installed we will monitor them continually for performance and wear/play and report back. If they work out well I will post what materials we are using for those that also want to go the custom route.
