Rick, Thanks for the explanation. I won't be putting spacers anywhere near my car. The reasoning behind my original question re their legality was because on my commowhore the wheel nuts are about 15mm long so the thread pokes thru the end when tightened. So therefore spacers would fit and the nut would have the full effect, but as you say the stress would sheer the bolt due to the load being placed further along the thread.
Just out of curiosity, what wheel/tyre combination do you have and what were the pirellis worth? I realise how important tyres are, it's just that most guys seem to tear rear tyres apart like there's no tomorrow. Maybe go for ultra sticky on the front to keep the car pointed in the right direction and a little cheaper tyres on the rear? thanks again for the explanation and pictures(I think you should become a graphic designer:) cheers, Adam ----- Original Message ----- From: "Rick White" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, March 27, 2002 11:04 AM Subject: Re: Adam/spacers & Wheels > Adam. > The reason spacers are illegal is because, > > 1: when you bring the rim out on spacers no mater how small they are is because wheel studs were designed to be the sise they are for one reason to be light. > There main strength is right where the wheel bolts up against the hub. > If you bring the hub out any distance the stud can bend then sheer as I have seen many times before. > > One of the main reasons they bend then sheer is because dodgy buggers do not design them properly (The spacers that is). > > If a spacer was machined up especially to fit onto the hub like a rim fits onto the hub(fitting onto that little lip) and then there was a little lip for the rim to sit over on the spacer there would be no problems. > > The reason for this is the rim won't be able to move no matter wot you do to it. > > But no one builds them right so things beak and accidents happen. > Most of the spacers I have seen are discusting they have slotted holes sso they fit every thing. > Just imagine going over a spped hump a little to fast with your rim boolted to a flat disk that has slotted holesthe rim and the spacer(disk) will sit together but they normally slip of the hub making the studs bend and then some times sheer. > > > In Perth you can use spacers on a engineered ar that has had a engine swap to pass this you need to have the engineer sign of on them and he has to make sure you use hardened studs for one and that your spacers are individually built to fit your purpose not just be a flat disk with holes in them. > > In my mind there is NO REASON EVER that a Datsun that is mainly a streetcar should ever need spacers and any one who fits them for the street just to fit bigger rim and tyre combinations needs there head read. > > If you want the extra performance of the wider tread foot print, don't be a tight arse and buy good quality tyres that fit properly with out having too do stupid things to your car to make bigger tyres fit. > I love my Pirelli's on my 1600 wagon thay are the best thing I have bolted onto her since I bought her. > > unlike the crappy Brigestones that were on the rear that felt like I was driving on oily roads all the time. > > Any how I hope you take every ones advice. > Especially now you may have some understanding why they are a bad thing to have on your car. > > All the best. > Rick White. > > normal hub(rim fits over the number ones in the centre) > > ____________1__________1___________ > > Badly designed spacer centre hole too big so it doen't fit properly onto the hub > ___________ __________ > > this is how a hub and spacer shold fit together. > > =============1 1============= > > > Sorry about the orny piccs but it is early I hope you get my drift. > > > _____________________________________________________________ > Get Your free Ozdat Email Account > ---> http://www.ozdat.com > > _____________________________________________________________ > Run a small business?
