IMO it doesn't do anything near what the brake force distribution system does on decel so impact seems negligible to me, maybe I'm wrong that's my butt dyno readout says I have it right here

You'll know if it's starting to wear if you start getting more inside wheelspin in 2nd and 3rd gear corners. Mine still makes elevensees at 91,000 miles but it's pretty clear to me that it doesn't react as quickly as it used to when it was new, so just being able to leave two stripes isn't enough info
I do like rain sessions, so your suggestion is another reason to look forward to them!

However, I don't understand what you mean by IMO it doesn't do anything near what the brake force distribution system does on decal. Are you referring to the stability management (eg MDM level)? Or is that something that goes on even with all nannies switched off?
