they look pretty safe... fairly smooth with small holes for break cooling not that i imagine that's an issue on any normal car. so if you like the look and the price is right go for it... if you want perfect aero look for something wich is even more smooth or convert some tray ol lids. than again the impact on FE is likely very small, so while a noble effort to improve things i wouldn't go extreme. and in that case these will provide a nice improvement over a bare wheel and they look nice too
