You can also use the stock rear caliper as a parking brake with wider than stock rotors. In fact, Wilkinson uses stock rear calipers with 1.25" wide rotors. He splits the caliper mounting bracket and welds it back together with two pieces of stock, of the appropriate thickness, added between the two halves. He also makes longer pad retaining pins. The only knock against using the stock rear caliper as a parking brake is it's a bit heavy for the application. I've seen guys drill a bunch of lightening holes in the bracket and machine the hydraulic portion off of the caliper, in an effort to lighten the assembly.

I used a parking brake caliper made by Stop Tech. It's called the ST-10 (http://www.stoptech.com/Products/BBK/caliper_descriptions.shtml) and it works brilliantly. It's compact and holds the car on a very steep grade without any problem. It could also be lighter but it's still the best parking brake solution I've come across.

The problem is, it's not an inexpensive way to go. If I were doing it all over, I'd use the stock rear calipers as a parking brake.
