Mag wheels are good, 16 " tyres would be good too and Yokohama is great..so far everything seems to be quite good. Yokohama A- Drive would be a good tyre to begin with. In case you want something better then go for Yokohama S- Drive.
However, keep in mind that these are performance oriented tyres. So while they will offer great performance and handling, they will wear out relatively soon as they are made up of soft rubber compound for high grip levels. In case you are looking at something which offers quiet and comfortable ride quality and has longer tyre life then go for Continental Conti Max Contact MC5.
