powershotnt Posted November 10, 2009 Share Posted November 10, 2009 I am going to do a V-8 conversion and want to switch to a 5 lug hub. I have searched the suspension threads but found nothing. 81 non turbo 2+2 Quote Link to comment Share on other sites More sharing options...

powershotnt Posted November 10, 2009 Author Share Posted November 10, 2009 check out modernmotorsports.com thank you..they have a 4 lug honda conversion which really opens up my wheel tire options. Quote Link to comment Share on other sites More sharing options...
Jared Posted November 10, 2009 Share Posted November 10, 2009 The rear is a straightforward swap to the 5 lug Z31 stuff, the front is a little more complicated. Quote Link to comment Share on other sites More sharing options...

I assume you have to go with the Z31 bearings also for the hub and all brake components? Quote Link to comment Share on other sites More sharing options...
Jared Posted November 10, 2009 Share Posted November 10, 2009 z31 brakes are not a bolt on, but the outer hub, bearing and inner flange go in with the z31 axles. Quote Link to comment Share on other sites More sharing options...
frank280zx Posted November 14, 2009 Share Posted November 14, 2009 Actually the z31 stuff does bolt in, with the rear brakes accordingly, just make sure you get the later calipers and machine (or if your going cheap) grind down the saddles about 0.5mm http://forums.hybridz.org/showthread.php?t=120603&highlight=s130+lug The fronts take some adaption but you could use a z31 set up as i did on my ZXR So the rears swap fairly easy! You need to run the z31 cv's though. Good part is that apart from the hubs being a direct swap, so are the bearings, brake disk and 87 calipers!! Here comes the tricky part, between the two wheel bearings there is a spacer it needs to be the correct lenght, so mayby not as much tricky as needing the right parts for the job, and to be sure that you dont get funky bearing loads. Note that because the Z31 stub axle is tapered, use the Z31 distance piece (bearing spacer) as the Z31 “B” spacer is the same length (55.95mm) as the ZX “M” spacer. If your 280ZX rear lower control arm housing needs the “N” length spacer (55.85mm) use the corresponding Z31 “A” spacer and if you require the “P” length spacer (56.05mm) use the corresponding Z31 “C” spacer. This opens up a lot of possibilities for 280ZX applications as the Z31 stub axle came in three different varieties: a four-lug hub, a five-lug hub and a five-lug hub that used a vented rotor (which has a thicker wheel mounting flange). Utilizing either the turbo or the non-turbo Z31 companion flange you can use either the ZX CV axles (3 bearing joint) or the stronger Z31 turbo CV axles (with the 5 bearing joint). Strange thing performancewhise but I noticed that the diameter of the ZX stub axle is actually smaller (30mm vs. 32mm) than the first generation 1970-78 Z cars. The Z31 stub axle starts out at a 30mm diameter but then it tapers out to a diameter of 35mm where the wheel flange is. Nice upgrade. The fronts need some work to extend the control arm etc. nothing to fancy, but still something to take in to concideration. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted November 14, 2009 Share Posted November 14, 2009 Biggest problem with the front is that the offset is pretty different from 280zx to most any rear drive nissan made after it. Quote Link to comment Share on other sites More sharing options...
