I had but there seems to be a little debate on using them on old rotors. I figure i will just switch over when it's time to get new rotors. Unless anyone wants to sound off on not having any problems with that combo.
I am running cross drilled rotors ( a debatable choice also)
The pads were "Autozone" carbon/ high performance.
This setup was ok until the right side started to squeal.
I had decided to wait until, I had time to resurface the rotors, to use the 100 pads. (C-Dan's advice)
I got another set of autozone pads, and when I started the work I noticed that the reason for the squeal was: a very poor match between the rotor and pads (some of the pad did not even touch the rotor surface)
Since the 100's had a much better alignment, and not having time to r/r the rotors, I went with latter of the two choices.
I used no shims, and some of the orange colored, anti squeal goop. (forgot brand name)
So far, no squeals, vibration, etc.
maybe I just got lucky??
Moralien - I'm no mechanic, just telling you my experience. I went with the 100 series pad, and did not replace or resurface the rotors, as they looked to be in excellent shape (and at the time I didn't know about the larger footprint). I've had my '97 80 for about 25,000 miles, so the rotors may have been new when I bought her, and I still had about 1/2 the pads left.
After 2 months, I checked the pads and they are wearing evenly, as are the rotors. They are a very tight fit, so I didn't use the shims or any squeal goo, and have had no problems. I did however need to remove some brake fluid. 100 series pads are the way to go, they noticably improved my braking.
