1200rc, they would be hilux calipers not land cruiser ones. They are pretty much the same caliper but the hilux ones are designed for a solid rotor instead of a vented one. So you would have actually been running 60 or 75 series calipers on your car not hilux ones. As far as I know no hilux came with the staggered piston calipers on a vented disc

Old_school. Can't really speak for running drums. But with disc all round and a 240k master cylinder I ran a willwood proportioning valve otherwise the rears would always lock up
