highly Posted July 20, 2009 Share Posted July 20, 2009 I purchased a set of "never installed preowned" wheel adapters some time back. When I purchased them the seller indicated they were for the S30 to fit Honda wheels. The adapter's center hole is too small to fit cleanly over the S30 hub alignment flange. The adapters are marked as follows: MML CROW 4x114.3mm 4x100mm Made In USA The inner diameter measures out to 70.28mm Are these designed for something else? Possibly a ZX? It would be good to know what they are supposed to fit for resale or trade towards what I need. I'd have to press the studs out to chuck it up in the lathe to make them fit, and I really don't want to do that. Thanks -Todd Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted July 21, 2009 Share Posted July 21, 2009 Contact Ross at Modern Motorsport. I believe that's where they came from based on the MML stamping. Quote Link to comment Share on other sites More sharing options...
Savage42 Posted July 21, 2009 Share Posted July 21, 2009 Well, being "preowned" limits options. If you have a friend or machine shop, just put them on a lathe and machine the hole to the size you need. You won't have to take off too much material and don't have to go all the way, just open it up enough to fit over the lip on the center of the hub. Won't take too long or cost too much. (At least that's what I would do) Also clean up any rust or buildup on the hub and take a good measurement to see how much of a difference there is and how much the hole needs to be enlarged.

ezzzzzzz Posted July 21, 2009 Share Posted July 21, 2009 My advice was to see what Ross had to suggest only. That said, go with Savage's advice. If you were close you could chock them up in my lathe and knock it out in just a few minutes. Quote Link to comment Share on other sites More sharing options...
highly Posted July 22, 2009 Author Share Posted July 22, 2009 Chucking it up in the lathe IS a serious option; My 9x20 will support the swing, but there's no way to chuck the part without making the fixture in either my 3" 3-jaw or 4" 4-jaw. You can't get around the studs to grip the outer face. I will try to get ahols of Ross later today... Quote Link to comment Share on other sites More sharing options...

highly Posted July 22, 2009 Author Share Posted July 22, 2009 Propane-induced heat and my 1.5 ton arbor press indicated that wasn't going to be as simple as you would think. Those bad boys are IN THERE. Considering these adapters are closing in on $200 after shipping from MM, I was not going to rush in to tear them up if I can help it (have to successfully remove and replace 16 studs keeping them square) ... so I posted for advice I'm still considering how I might make a >simple< jig to turn these bad boys with the studs in place while keeping them concentric, but in the meantime want to explore the other options. So nobody happens to know the hub size for a ZX? Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted July 22, 2009 Share Posted July 22, 2009 My 13x40 would do the job. A local machine shop should be able to knock this right out for you. Quote Link to comment Share on other sites More sharing options...
highly Posted July 28, 2009 Author Share Posted July 28, 2009 Found a backing plate locally for cheap and milled some slots in it. Bolted up the adapter with four 12x1.25 nuts, trued to center with an indicator, and made the cuts. Done. Quote Link to comment Share on other sites More sharing options...
hughdogz Posted July 28, 2009 Share Posted July 28, 2009 ...Are these designed for something else? Possibly a ZX? You have to run Honda wheels if they are 4-on-100mm bolt spacing...you probably already knew that though. All S30's and S130's (and early Z31's) run 4x4.5" or 4x114.3mm bolt patterns. Honda wheels run 4x4.25" (or 4x100mm). Honda studs are M12x1.5 and Nissan studs are M12x1.25. Hope this helps, -hughdogz Quote Link to comment Share on other sites More sharing options...
highly Posted July 28, 2009 Author Share Posted July 28, 2009 I've just upped my dose of Zyban to try to quit smoking (again) so my head's a little more fuzzy than normal today. Literally, I'm not in my right mind at the moment! Normally I'd respond sarcastically in a just-poking-fun way, but I don't trust myself to type it in a way that would be funny and not just piss you off. It's funny in my head, though. The original problem was that this adapter didn't fit on my 280's hub because the wheel bearing interfered with the too-small "doughnut hole" of the wheel adapter. Fixed it by opening the doughnut hole on my lathe to tightly fit over said area of interference. All better now. Mostly I was curious as to what hub this adapter was actually designed for. Seems nobody knew. It's REdesigned to fit a 280 hub now! Oddly, the studs on this particular set of adapters... the Honda bolt pattern part... are threaded 12x1.25. Pain in the a3 as I can't use my original locking tuner lugs for those wheels and have to buy another set...! WHAT were they THINKING?! Big head + little arms... "I don't think this plan was very well thought out!" Quote Link to comment Share on other sites More sharing options...
