we have made our way to the P85+. we love the way it handles and are thrilled with the vehicle overall, it feels rock solid. I added my own all weather mats from Costco and without thinking about it, I took out the OEM mats and then went on a weekend trip to Portland. This was the first time I really noticed the road noise, it dominated the stereo. our concrete highway's here get to be like creek beds and that sound seems to get worse in the winter, not sure if it's the denser air or the hardening of the performance rubber or what. When I put the OEM mats back in, under the rubber mats, the sound diminished but was still quite noticeable at higher speeds. I am wondering if anyone has a decent solution for reducing the road noise. I am switching over to 19" for the winter, and maybe for good with some Michelin primacy's, hoping to find the right balance of dry grip and wet performance out of a single tire for year round in this northwest climate. Presuming the breakthrough sound is still an issue after the new tires, I don't want to spend a wad of cash on lining the car if it's not going to take care of the issue. I haven't found a review that suggests sound proofing really helps high speed sound. I am wondering if there is something I can add on top of the carpets as most of the sound appears to be coming from the front wheels/wheel wells. curious if there is a simple solution, not looking for perfection, but if there were something simple to apply that reduced the noise even 20% in the 70-80 mph range, it would be something I would probably get used to and not notice. to do something more extensive, like having all the carpets and seats pulled and the entire floor coated, I'd need to be pretty convinced that it would make a big difference. any feedback appreciated!
