QUOTE The hub on the right is from an early non vented car 65-68. The thickness changed when they went to vented rotors to support the weight. 69-73 hubs were the same. I believe in 74 the hub stayed the same but the wheel bearings changed size because a thicker spindle on the strut. More than likely the other way around. The thickness didn't change because of the weight, it changed to allow the new vented rotor to move "outward" and center in the caliper groove. It got thinner. So, the caliper received 7mm spacers, they spaced the caliper nose out by 7mm. The hub would then be thinner (rotor mounts to the backside of the hub) by 3.5-4mm to split the difference in the 7mm spacer. The thinner one on the right should be the later hub. Spindles on 911's were always the same in those years. Part numbers should tell the complete story. |
