have had two conversions on my 240z first went with the hilux or for runner calipers for solid discs nice easy conversion just bolt straight on good for upgrade and normal street work with good pads Since then have gone for the vented hilux for runner calipers of with falcon vented discs and carbon fibre pads from Gtr calipers god do they stop well still using standard master cylinder but had to cut caliper mounts off strut and make new ones which i bolted to the orginal disc cover plate holes which were tapped out to 10 mm bolts sure stops well now just dont stomp on them first time flatted spotted one set of tyres.
