JimC Posted November 9, 2009 Share Posted November 9, 2009 Guys, I'm going to be doing some experimenting with wheel spacers in attempting to widen by wheel track on the supra. The only bit of info im struggling with is to do with the wheel studs. I'm aiming for approx 15mm spacers and am likely to need some longer (15mm extended) studs. Without getting a stud out and checked, Im not completely sure on the details. As far as i can remember they are M12 x 1.5 but im not sure about the spline dimensions. Here is a link to some 20mm extended toyota studs..... http://cgi.ebay.co.uk/Toyota-wheel-studs-extended-20mm-Mr2-Corolla-x16_W0QQitemZ290294884832QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item4396ec69e0 ...would these work? Thanks Jim Quote Link to comment Share on other sites More sharing options...
dude Posted November 9, 2009 Share Posted November 9, 2009 They will be ok but the knurled bit will need turning down slightly to go in the hub. Quote Link to comment Share on other sites More sharing options...
JimC Posted November 9, 2009 Author Share Posted November 9, 2009 When you say the knurled bit, isn't that the splined diameter that presses into the hub? Quote Link to comment Share on other sites More sharing options...
merckx Posted November 9, 2009 Share Posted November 9, 2009 They will be ok but the knurled bit will need turning down slightly to go in the hub. I did just that. When you say the knurled bit, isn't that the splined diameter that presses into the hub?. Straight knurl or splined type. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted November 9, 2009 Share Posted November 9, 2009 I went for a set of H&R 15mm hubcentric spacers for a JZA80 and the kit included longer wheel studs with all the right dimensions, spline size, thread etc. These were the ones IIRC: http://www.europerformance.co.uk/pages/products/product_info.mhtml?product=3884109 Quote Link to comment Share on other sites More sharing options...
bodilx6 Posted November 10, 2009 Share Posted November 10, 2009 You might want to get hubcentric spaces with build in wheel studs. Under all circumstances make sure the spigot hole fits the hub or you might end up loosing a wheel while driving. It's dangerous stuff messing about with spacers, studs and so on..

You need to machine it out? The ones i took out were splined and the ones I put in, the same as the ebay ones mentioned, went straight in their place. I didn't machine anything Quote Link to comment Share on other sites More sharing options...

The splined diameter fitment into the hub looks like a direct replacement.... Quote Link to comment Share on other sites More sharing options...

Under all circumstances make sure the spigot hole fits the hub or you might end up loosing a wheel while driving. It's dangerous stuff messing about with spacers, studs and so on..I personally would avoid using thin spacers with built-in studs. I've just put 10mm on the front of my car with longer wheel studs. They're a doddle to fit and are hubcentric. They're available in 15mm also. I got them from http://www.wheels.uk.com - there are other suppliers of course.

bodilx6 Posted November 10, 2009 Share Posted November 10, 2009 for some good info, do a search on Chris Wilson as name and spaces as subject.. Quote Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2009 Share Posted November 10, 2009 To back up your point about bolt on adapters or spacers in general? Need4Speed is correct in this instance. I wouldn't touch 15mm adapters with a barge pole. For a start half of that thickness is used by the head of the stud that goes in the back so you are only left with around a 7-8mm wall between the back of the stud and the face of the wheel. This means that at any given time there is only that amount of aluminium holding your wheels onto the hub. I've heard of people running them and not having any issues. 25mm minimum for me on the adapters though. IMO noone on this forum would notice a difference with using 10mm spacers, as long as they are hubcentric and fitted appropriately. Quote Link to comment Share on other sites More sharing options...

The ones i took out were splined and the ones I put in, the same as the ebay ones mentioned, went straight in their place. I didn't machine anything The studs I bought had a deeper spline than the stock ones, I tried fitting one but it was far too tight a fit to pull them into the hub without causing damage. I just put them in the lathe and used a hand file on them to reduce the spline a little. Quote Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2009 Share Posted November 10, 2009 I thought it was a case of the tighter the better. I just used a 10" ratchet, did the job nicely. Did it with the old discs on to save the hub face. Took a bit of grunt but went in fine. The stock ones probably didn't have as deep a spline as they had been pulled in and out of the stud bore. That would have taken the edge off of the splines. Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted November 10, 2009 Share Posted November 10, 2009 The spacers I used came with studs and they were a perfect fit. My tip? Don't use a good wheel nut to pull them through! Quote Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2009 Share Posted November 10, 2009 The spacers I used came with studs and they were a perfect fit. My tip? Don't use a good wheel nut to pull them through! Seconded. Wouldn't advise good alloys or brake discs either. Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted November 10, 2009 Share Posted November 10, 2009 Seconded. Wouldn't advise good alloys or brake discs either.A stack of 12mm washers and an old wheel nut... and a compressed air wheel gun! Makes things easier. Quote Link to comment Share on other sites More sharing options...
Kev_A Posted November 10, 2009 Share Posted November 10, 2009 At present my front wheels have an offset of 36, if I used 20mm hubcentric spacers would the wheels then catch the arch? Quote Link to comment Share on other sites More sharing options...
bodilx6 Posted November 11, 2009 Share Posted November 11, 2009 My point was that if your current wheel doesnt match the spigot hole 100% you are putting the cars weight on the studs. That might have worked fine untill now, but there have been several reports on this forum about people chaning their studs with wheel-loosing results. That spooks me.

You aren't putting your cars weight on studs as the spigot doesn't take the load. No need to go into it again on this thread, search for Jakes thread on the hub spigot's and have a read towards the end. Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted November 11, 2009 Share Posted November 11, 2009 New studs made to the correct spec must be better than old ones. Quote Link to comment Share on other sites More sharing options...
