I spoke with the guy that makes the thicker clips, and where the critical part is hardening

He's willing to make a set for us if I can get a few guys to commit

Need to talk to Al and see if I can get the blessing for this to be a test run for a 2020 RCR, but the single best thing I did to kill knock back is replacing worn c clips

If I can further redurlce end play by .01 on each side it will be mint.

All the bullshit around axle end flex and caliper springs pales compared to simply taking out end play with thicker or not worn c clips
