Ok, so I thought it was just bad roads that contributed to all the clanking and banging from loose gravel and pebbles under the car and wheel wells. It's not just the roads... or in my head! A buddy of mine was jogging on a road that was scarified (digging up for new top layer of pavement) he noticed a BMW went by.. no noise... then a Porsche and he told me he almost laughed out loud as all he could hear was rocks/pebbles clanking underneath that car.

I did a quick search and it appears the some Porsches (991s as example... and 718s) indeed have little protection or insulation under the wheel wells and this is definitely more of an issue for 'us'. My car is new so I haven't rolled under to see what it's like but there has to be a way to quiet this down? It's so **** annoying. I know @Viffermike had a post mentioning this somewhere. How can you guys ignore this? It's more prevalent on side streets but it's so nasty.

This will drive you all crazy. My house is about 1/4 mile from a sealed and maintained road. Access to my house requires I drive on asphalt millings (recycled road material). Imagine driving on loose, pea-sized rocks. Yeah, I hear those stones rattling about every trip, but it is what it is. Once I get to the sealed road I go slow for a bit to throw most of the rocks from the tread. No stone chips yet :|

If it's as bad as that then I'd suggest you get down & check on top of your suspension arms from time to time. You'll be surprised just what can collect on top of those arms & once there because of the raised sides it has a horrible habit of staying there.
