Thanks for that, Im very happy with them.
I tried the rim again tonight and it needs a 5mm spacer to mount the wheel to the hub, this gives about 1.5mm clearance from the rim to calliper without grinding the Nissan logo off. Im test fitting them on my 180sx thats runs R33 GTST brakes as I haven't fitted the other set to the M35 yet. I don't want to run a spacer so it looks as thought the R33 GTST brakes are going up for sale! If I ordered a different rim face it would have fit but I wanted to keep the spokes as flat as possible and was told the A disk should have fit.
Im keen to look into the Murano brake option then, Ive been searching the net for more details but only find single piston callipers. So do you know if the Murano twin piston brake is standard on all models?
