Honestly, unless your driving at a race track or just driving the PISS out of your car....vented rear rotors are overkill. I don't think Subaru makes a vented rear rotor in the 11.4in size. The turbo legacy vented rears are smaller I believe. Since I have never driven my brakes 10/10ths before, and probably never will, I didn't need an increase in sustained performance as in reducing brake fade and such. I was really going for a better look. Those stock rears are just so tiny. These fill out the rear wheels nicely. And it's not expensive at all.
