Hmm, that's a pity about the calipers - I too want to run stock hubcaps so need to be careful with the caliper selection when I get around to trying out some parts for fitment. Pondering Volvo calipers as a friend has these on a 67 Prince and they don't seem too bulky.
Keep at it - I'm sure it's all worth it in the end.
Well, I'm glad I stumbled upon this thread! I've recently acquired a WP411 project car and one of the first things I wanted to address is the brakes as I've got to put the system back together anyway. Have just started digging around the internet for information before I measure everything up and start sussing out what other OEM parts I might be able to harvest for it.
Do you know if there's any truth to 240Z stock front brakes fitting these?
