Refurbished caliper and mounting bracket assembly. I opted for the kit with the "OEM" ceramic pads by Bosch. The calipers arrived with pads pre-installed, and I thought "how nice". After I was finished with the project I noticed a set of Bosch pads in the bottom of the box - the calipers came with pads preinstalled, but they were the cheapo semi-metallics. I had to tear it all apart again and swap pads. The brackets have a different offset. The calipers are slightly different and take different pads.

V8 pad on the left, V6 on the right.

320mm vs 295mm. The odd slot-patterned rotors were on closeout at $40.

V6

Super-easy swap only required three bolts - two on the caliper mounting bracket and the banjo bolt on the caliper - and bleeding. It's so cheap and so easy there is no reason not to do it next time you do a brake job.
The V8 caliper is 9mm closer to the wheel compared to the V6.
