There are multiple directions you can take, all of which will require you to change your steering knuckles to those from a 94' - 95' SHO/ Taurus/ Sable with ABS.
I'll provide a link to each and post each in the order of which I consider them to be, from the street stuff to the track stuff.
1994 - 1995 Upgrade ($200 in parts if new and after cores) - Increases rotor size to 10.9 Inches and offers minimal braking increase. Parts Needed: 2 94' - 95' Calipers, 4 94' - 95' pads (601), 2 94' - 95' Rotors. On a scale of 1 to 10, these would be a 2 as far as performance is concerned.
96+ Brake Upgrade (Starts at $279) - This is by far the most common and lifts your rotor size to a stout 11.6 Inches. It also raises your rim requirement to 16" inches. As for braking, you have a nice healthy feeling pedal and pretty decent pad options. On a performance rating: 5 out of 10. Link:

PBR Light-duty Upgrade ($459) - While this upgrade utilizes the smaller sized rtors, they are thicker, and the caliper is made of aluminum which allows it to dissapate heat much better. The calipers also have a great pedal feel, even with the increased capacity. Pads are a common size and can be had from cheapy Autozone varients to extreme duty track pads. On a performance rating: 6 out of 10. Link:

13 Inch Front Upgrade($649) - Large rotor, but overkill for all but full time track cars. Braking performance is close to as good as it gets with essentially no fade. PBR heavy duty twin piston calipers are utilized and 1.1 Inch thick rotors are also used. The required rim size goes up to 17 inches and the required power to overcome the rotational mass also goes up.

Performance rating: 9 out of 10 Link:

Baer Claw 13" System ($699) - Utilizing Baer crossdrilled/ slotted 1.1 Inch thick rotors, this setup would be best suited on a full time track car. Calipers are Heavy Duty, PBR branded, Twin Pistons. Performance Rating: HOT!

That's all for me. I've spent the time I had allocated for surfing replying to this. Hope it was of some help!
