rudypoochris Posted January 5, 2007 Share Posted January 5, 2007 Is there any difference between the front wheel surface positioning on 280z vs 240z hubs. Is the offset changed basically (not did Nissan specify different offset tires, but are the hubs themselves different)? Thanks! Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 5, 2007 Share Posted January 5, 2007 They are different and this is why you need 280 hubs for the Wilwood brake setups. I believe the 280 hubs are 10mm different than the 240s. Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted January 5, 2007 Author Share Posted January 5, 2007 Ah i see. Do you know if they are 10mm inwards towards the body or outwards towards the fender? I was assuming that the 280z hubs were the same for wheel mounting but offset the brake disc differently. Thanks for the heads up! It would be nice to gain some wheel clearance, so I am hoping...

bjhines Posted January 5, 2007 Share Posted January 5, 2007 I think the wheel offset is the same... It is the backside offset of the brake-disc hat that must change... The 240Z and 280Z front discs are different part numbers...yes? The 280Z hubs are considerably THICKER than the 240Z hubs.. otherwise the wheel face mounts in the exact same position...

JMortensen Posted January 5, 2007 Share Posted January 5, 2007 I don't think they're 10mm thicker. I've got some 240 and 280 hubs out in the garage. Maybe I'll head out there in a bit and compare the two. I know the backside where the rotor bolts up is different, so that alone makes them unswappable due to caliper/rotor offset differences.

JMortensen Posted January 5, 2007 Share Posted January 5, 2007 John is correct, the difference is in the thickness of the flange, so it's a rotor offset thing not a wheel offset thing. The part that threw me off is that the protruding flange where the wheel bolts on is the same thickness but not scalloped on the 280Z hub. Then further back it tapers away from the hub and gets smaller, and that smaller diameter area is the part where the flange is thicker.
