Broken screw
Harbor freight sells easy outs that are used to remove broken screws. Requires drilling proper size hole and putting in easy out, which then locks into broken screw. Then it is twisted counter clockwise.

I would take the caliber off and work on it on the bench. Maybe even swing by a machine shop and have them take a look at getting it out before i'd put the torch to it!
I hate those pins... I have 2 stripped ones. I just leave them in place and pull the caliber off to change the pads. I like the brakes, but I Hate changing the Damn pads!
if i hade a spare 4k, i'd buy the Brembos!

Thanks for all the tips guys 
I have no reason to think the bolt is stripped ???
You would think the broken tip would fall right out but it didn't when I turned the caliper upside down. And I have driven the car two weeks and at the track .... was hoping it wasn't going to be there when I checked yesterday.
Don't have a magnet either .... limited tools

If you sheared the torx bit off in the clockwise tightening direction an easy-out may not be the solution. It will be in very tight.
Remove the caliper from the spindle mount. Remove all the padlets and all the other brake pins. Use a medium pair of channel lock pliers to clamp on the inside of the pin (inside the brake caliper). There is a SS collar on the inside end of the pin. Just clamp over it, tightly. Use a small hammer to hit the channel lock pliers to start the pin out. Make sure you are going counter clock wise looking from the outside of the caliper towards the pin, for this step.
Once you break it loose you may need to remove the SS sleeve covering the head of the pin if the channel lock pliers damaged it enough that it will not back out of the hole in the caliper. A good pair of wire cutters is all you need to cut the sleeve. Replace the pin with a new one and be sure and to use anti-seize on the threads of all the brake caliper pins during installation.
I have removed many seized pins from C6 Z076 calipers due to the lack of anti-seize on the pins using this method.
Good luck.

And I always use anti-sieze
I did notice that SS sleeve as I was trying to figure out why I have such a brake squeal all of a sudden. Should these be lubricated? Please watch for another thread I'm going to start regarding possible brake squeal sources. Though I found it yesterday as one of the copper padlet retainers was bent away, not making contact with the pad like all the others. The squeal went away after testing it yesterday but was back today though not quite as bad .... but still unnaceptable. And its not the normal squeal ..... I have over 37K miles so I know whats normal.
