Saw a zed with a set on yesterday bizarrely, i know they are a great wheel and will do the job you want (light and widths), but think they are very bland and dont suit the 350 imho of course.
Why not a nice set of te37's, i know just the man selling some
Or if your looking for lightweight, some Desmond Regamasters, BBS Rg F1's, SSR Type C, Racing Sparco Viper R's, Volk Ce28
This might help
