Brake Caliper Bolts - What are you doing?
Since it is recommended that whenever a caliper bolt is removed (to change pads or rotors) that they should be replaced with new.
I am curious if those that track are changing the bolts with each pad change. I believe that the recommendation may be due to an expected normal service interval with many heat cycles and corrosion. Since it adds about $80 to the part costs, I would like some opinions.

All makers do that, for liability reasons. I have never replaced them based on that - and have done countless swap-in/swap-outs on street vs track pads, etc. The key really is to torque them correctly each time. Too tight and you get some stretch and weakening of the threads. Too loose and they can back out. I use a 3/8" Snap On Electronic Torque Wrench and that's one of the few things I actually try to torque correctly on the car!

I replaced the bolts with stainless studs. Now the caliper slides easily over the studs and is secured with bolts. It's MUCH easier to change pads now and there is no risk of damaging the alloy upright by possibly misthreading the OEM bolts. One of the best mods I have done. Not cheap, but worth it.

It's a great mod. Reduces brake pad changing process time by half. No more blind searching trying to properly screw the steel bolt into the alloy upright. That was often scary!
If you are just changing pads once or twice in the lifetime if the car it's not really cost effective. But if you change pads for track events, even just a couple a season, they are well worth it.

Thank you, I have been struggling with what to buy myself for Xmas, you solved the problem. The 991 brake pad replacement was such a step back from the previous models.
