Thats a lot of good information. I hear a knock/click sound over uneven road (like when driving over the pavement at the entrance of a parking lot which is sometimes banked as well). I've spent enough on diagnostics with 5 different mechanics and 2 dealers - no one can figure it out lol So I thought f**k it I'll just get coilovers but we share the same winter concerns (Toronto). I'd really like to get OE to (partially at least) get that original comfy feeling but I have to sell a liver. And for all the after market parts to be honest I'm not sure about the quality of the ride compared to OE - maybe someone can enlighten me.
