Sorry but even assuming a Stoptech caliper is same on the truck kit as on a miata kit (I would be surprised), placement relationship vs the spindle and hub is totally different on every vehicle so all fitment info with regards to that caliper on miata just has no relevance to fitment of that same caliper with the truck. Think of it this way, no standards for hat offsets that hold the rotors, that's done vehicle by vehicle depending on space available. Even within generations of Miata where we are using the same caliper for different kits with same rotor diameter the fitment templates are totally different and our fitment experience with a certain popular 4 piston Wilwood on the NA/NB generation miata tells us precisely zero about the fitment and wheel clearance on ND miata. Was looking at these issues just yesterday in connection with new wheel designs with Konig, have to send them templates for each generation of Miata we want to clear, not nearly enough to just tell them our NA/NB fitment data covers ND for same calipers on similar 11 inch rotors, it just is not that simple though I wish it was. Thus, we are back to Tirerack on that or any vendor who has actually put their hands on that truck with the brakes you want with an eye to wheel fitment. Otherwise, you are flying totally blind here.
