Nah, think you miss my point- I’m not saying there’s no difference (I’ve no experience myself), just that in general some people want to be impressed by a new part or change, particularily when it was expensive.
Frinstance, I once changed the rear caliper on a mate’s motorbike and at the same time, gave the front once a wee cosmetic clean and polished the logos back up just because they looked silly with the new rear. He was well impressed with the increase in front braking 😉
Incidentally, in the class war, what wins- PUSH or Kashima?
