My issue is exactly that, whenever it's cold outside (under 50 degrees) there are weird sounds coming from the front end of my Z when going over bumps. Sounds like things are loose but as soon as the temperature outside warms up the sounds go away. Shocks going bad maybe? I believe they're still stock so maybe it's about that time?
