Noise is worth it if you're going to track or have heavy canyon runs. Otherwise, for bite and quiet, stock may be easiest. Also fluid flush?

Never had the 325/328, had a 330xi, 330i and a 335xi.

The HP+ dusts way less than stock. We’re pretty much all familiar with the sound.

Fresh fluid in the system, and all the calipers are working fine and moving freely

I want quiet so I'll just leave it the way it is.

JV do you think it's worth trying a new set of textar pads just for kicks? We don't even know what's in there right?

I honestly don't know. I've never used Textar pads.
