Can't really beat the general altimax artic studded tires. They have the sipes that go all the way down to the base of the tread. Where as the other studdable tires have the sipes only go about 1/3 of the way which is really stupid.... designed to make you replace sooner..
You can get wrx steel wheels in 16x6.5 which will work on your car with the brakes. Would be cheaper in the long run. But the tpms sensors would have to be dealt with. For your given price point you can't beat this.
