I lost undertray on the 360 very recently. It came slightly loose on the right side and I should have taken it in to get it fixed immediately. Instead I took it out for a short drive, and caught air under it. The whole right side dropped down and I could hear it scrap on the road. Immediately pulled over and then limped home. After a bit of fiddling, I was able to get it off and it is now gone in for repair. When looking at the way it is fitted to the brackets in the front, I have to say I am not impressed with Ferraris workmanship. For a vunerable area on a very low car, the brackets are quite weak and flimsy.
