I guarantee you'll overheat those 12" brakes on your first track day. Regardless, assuming you have good fluid, the pads will overheat first, and give you a little bit of warning before they fade entirely, so be aware of it, they don't really come back until the car has a chance to cool down. You can adjust your driving accordingly on the later sessions.

The bias spring will mean a little less work for the front brakes, which is good.

Auto-X just abuses the car and tears up wheel bearings. Brian Cunningham can probably attest to that.
