Hi Guys, i have been reading this forum for a long time and thought i should make a contribution.I happened across some Toyota s12+8 vented calipers (these calipers are made for a vented rotor , the rotor gap is 23mm i assume for a 20/22mm toyota rotor . there are 2 types of S12+8 calipers 1 for NON-VENTED and 1 for VENTED rotors, check the gap in caliper for width to know which one you are getting) cheap $25 a pair to fit onto my 1971 240z.Having read the sticky on upgrades i thought i might as well have a crack at it, using the Mitsubishi Magna front vented rotor from the TN,TM,TP model part # DBA 221 .A couple of issues came up that i haven't read in the other posts. The s12+8 vented caliper wasn't wide enough for the Magna rotor, the caliper(s12+ can only accept a 22mm wide rotor as the gap in the caliper is 23mm at its widest, and the Magna rotor is 24mm wide.So i made some 3 mm spacers (with recess for an "o"ring) to widen the caliper. Please see picture.The rotor centre hole was opened up from 69mm to 81mm to fit onto the hub and 4 new holes were drill at 103mm pcd to bolt the rotor to the hub.My 240z hubs are a little different from 260z hubs ,so i only needed to use 1.5mm spacers between the caliper mounting holes and the strut leg to move the caliper back (further inboard) to centre the caliper over the rotor.Next issue is my road rims are 14x6 eneki mag and won't bolt up the the hub as the new s12+8 calpiers are sticking out to far and catching on the back of the wheel spokes(run an 8-10mm spacer and buy some longer wheel studs part # NS 4570!).My 15x7 Performance Superlites with race tyres are just fouling a bit on the wheel hub(run 3mm spacer) and another set of 15x6.5 rims are fine. Plus install new brake master cylinder Nissan Patrol 1 inch part #JB1419
