IMHO... chassis should not need to be replaced because the grooves caused by downstop screws, when you adjust droop, you do it with a fixed scale that isn't affected by the grooves on the chassis isn't a real issue to have a grub screw slightly more tightened than other (well unless you make a nice hole on the chassis due to massive tightening and loosening of the grub screws).

Regarding ceramic bearings are only useful if you're looking for that small fraction of power robbed by plain bearings, stick to the Mugen ones well lubed and cleaned and spare yourself of burning high bucks buying a ceramic set. Better burn some sets of tyres.
