So your happy with 5 stud then?
I like the set-ups above but its still more brake than I need in my application.
Im going to do a single caliper with a handbrake, looking for a rotor no bigger than maybe 280mm. Definitely must be vented.
I really dont want to have to modify rotors to fit, so I may look at turning down the ends of the axles to suit some particular rotor.
For mass vs features I think Wilwood caliper with a built in handbrake could be lighter and cheaper than an oem spec caliper, especially by the time you buy the Nissan calipers, pads, and rekit them. To my thinking it makes the Wilwoods at around $300 a pair seem very good value for what you end up with. Being an F series user I am a little bit conscious of how much unsprung weight I am adding vs the durability of the rear end. I only wanted to put the minimum sized diff into the car that I thought I could reliably use to keep it as light as possible, so adding 2 large sets of oem calipers and a slightly larger rotor than I desire is not quite where I want to be.
I can see how its very good for the track though.
