You could safely order the stock 16mm RSB from a 2012+ Impreza, or you could order a 19mm RSB and bushings from a 2008+ STI. Several of us have the original 16mm RSB and bushings for sale from our 2012+ Imprezas.
In addition to the bar and bushings, you will also need end links, brackets (which install over the bushings), and some bolts to hold everything together.
