We all know that the lack of insulation (to save weight) and the rigid carbon fiber chassis can make it fun to locate a rattle. Thought this was appropriate.
Yeh, that's funny.My latest little rattle was driving Me nuts.All good to about 115km/ h then it starts, the sound was coming from the passenger side door, but couldn't find it. It wasn't until last Saturday on a highway it started again and my eyes looked across the corner front of the bonnet and F.......... there it was. The bonnet was vibrating at the same beat.The beater that helped install front Splitter at the time hadn't fully tightened that nut under the guard. Yes so there, rattles from door area, Check those nuts.
I once had a rattle in one of my cars (not my Alfa). It lasted for about a week and was driving me crazy , until I glanced up and saw that it was a windshield visor which was not clipped down.
