The people on here, yes, even most with very track capable rides but who
still drive them on the street, are NOT going to like those rear lower damper spherical bearing mounts at all, given how they HATE
any NVH.
Yes, those bearings will make everything much more 'precise' (or as
precise as one can be with a beam rear axle anyway) on a
glass smooth track, but they will knock like rabid jackhammers on any road surface not as perfect as said tracks.
This will happen even if they use the very highest grade, Delrin lined, race quality, spherical bearings.
