If you don't want to you don't have to use those clips. Many track guys leave them off. I stopped using them on mine. The C4 caliper is similar but doesn't use them. Just clean the dust out of where the pad ears sit. Usually don't use the piston seal either, they burn off at the track. I do lube those slide pins, I've been using Redline synthetic grease.

The pin just sticks into the caliper so pull it out and the boot will come along too. After a year the grease in mine turned to clay! So I generally check the grease after track events and spot bleed. Not to much else to do. Wipe the pistons if you press them in for new pads. I also clean the channels in the abutment bracket where the pad ears go. That can get full of brake dust. I don't put grease there, it burns off. Check them for spread once in awhile. I bought a bag of new bolts that go in those pins. With grease the pin shouldn't wear out but I've been thinking of keeping extra in case the threads in the pin wear out.

Aftermarket pads typically don't require the anti-rattle clips, but the grease should still be used at the ends of the pads. Might be a good idea to put some anti-squeal stuf on the back of the pad.
When you buy new GM calipers, you also get guide pins, the rubber boots and a little pouch of grease for the pins. You can get the guide pin grease at any parts store; Permatex has little pouches as well as small tubes.

I thought that GM grease was poor. It turned to hard clay and the pins couldn't move. I had to scrape it off and put Redline synthetic grease in instead. No trouble so far. It might be okay for street use but check it once in awhile. I thought the stock C5 pads were poor too. The Z06 pads were nice! But poor for track use.
