Sounds like a good all in one option. Shame they have ground off the words Willwood and repainted the calipers and bells. The first picture shows the AZ kit but it doesn't mention in the advert that it is AZ. The discs don't look like the big AZ one's, although its hard to tell. It also doesn't mention if its for a 240z or 260z (they are different) but I guess as it includes the hubs it doesn't matter.
A good price considering the extra's, but I think a new setup from AZ at not a lot more money would be the way I'd go. Having bought as used set before I would not recommend it as I ended up spending more than the cost of brand new in time and money on getting them working on the car. Now they are working, I can not recommend the AZ setup enough.
