Gotten quite a few years out of them b/c I don't race anywhere near as much as I used to. I think I got about 2 seasons out of them when the car was running mid 9s at 140 mph...and when I was able to go to the track fairly often.
I had a caliper seize up after 4 years or so. Bought a replacement and got the old one rebuilt...still have it on the shelf.
