The amazon link has two options, one has calipers. You can also find then on the PowerStop site.
I have +3s and Geiser springs. When you first install them you will add way more than an inch. With 37s I'm at 21 inches to the bottom of my hitch with the +3s being settled now for two years and I carry 250 plus pounds in the bed on a normal day.
I live in the southwest and in the summer months it gets hot. When I want to make a high speed run or when I want to pull my Airstream over the rockies hallin balls those brakes/pads along with the SS lines help.
I also flushed the system and added dot 4 fluid, it doesn't mind getting hot like the dot 3 does, it is a little pricey.

SRF is by far the best, but like you said, you pay for it.
Also, I thought I read in the manual that the Raptor comes with DOT 4 already. I mean, I remember being a bit shocked when I read it, cuz I wouldn't expect a factory vehicle leave with DOT 4, being it needs to be changed much more frequently.
Yup, it's in the Raptor Supplemental -
