wheels fitment?

[STEVE O]

HI looking to poss change my wheel,s I like multi spoke design,
would MG rover fit?as the pcd 4x100? thinking of 17 inch, thanks steve.

Hi pcd 4x100 is right I put 17" on mine and I like it

[STEVE O]

Hi
are they mg on your car? I have been offerd a set inc tyres
but multi spoke,will give thm a try, where yours a straight fit?
thanks steve.

Hi no Wolfrace, just showing how they look, had to get some spigot rings

Spiget rings are a must for any after market rims, you can get sets through the bay of e for a couple of £'s ,but make sure you measure up correct.

Those wheels re lovely mate... suit your car perfectly. Very nice

the problem you will get is 99.9% of spiggot rings are made for aftermarket wheels which are mostly 73.1 outter bore (the size of the inside diameter of the wheel where it fits onto your hub)

different cars have different hub sizes of 56.1 / 56.6 so on and so forth, there are stacks of different sizes. so the only way to get the correct sized spiggot rings would be to contact a company like autopartuk who can make them. the problem then is that they become real expensive for what they are

without spiggot rings imagine being on a tain doing 50mph with square wheels..... its not a nice experience

IMO the spigot rings are important only to help locate the wheels correctly. They add almost nothing to the strength of the wheel or the fastening onto the hub. On my Rota track wheels the spigot rings are a fairly soft plastic so wouldn't really add much strength. The wheel studs clamping the wheels to the hubs is where the strength comes from and the tapers on the wheels & nuts locate and centre the wheels correctly.

I know others are going to disagree with me but that's my opinion and backed up with my own experience.

[p34nut]

you are correct lazza these do offer no strength at all but without them even with the aid of using tapered nuts its beyond difficult to get wheels to fit perfectly central to where it needs to be resulting in the wheel sitting off centre. even a slight difference in this will have you feel a nasty shaking though the steering wheel usually most noticed at around the 70mph region (why this is most noticeable here i dont know)

if you think of this in an extreme example, the wheel being off centre is almost like having the effect of using an egg shaped wheel

its surprising what difference what a difference these make on the drive of a car but they are made very precisely down to a point of a mm

When my Rotas were first delivered they supplied the wrong spigot rings. I fitted them without them anyway and ran the car like that for a while including a track day without any problem. As long as you do it carefully and make sure the tapers on the nuts & wheels do their job (and make sure you have nuts with the right taper) it's no problem at all. Mine were perfectly balanced this way.
When they sent the correct spigot rings I removed the wheels to fit them and the only real difference they made was to make it a bit easier to hold the wheel in place while tightening the nuts. I run those wheels with 5mm spacers just to get the offset ideal so the spigot rings barely do anything at all now and I still never have a problem with wheel balance.
Wheel centering isn't all that important anyway. Wheel weight balance is far more important. My track tyres are Yoko A048 that have been used on an Elise racer for a couple of races so they are a bit out of shape. When you see my track wheels with those tyres fitted on a balancer you can see they run out by at least 20mm. What you have to remember is that tyres are pneumatic so they flatten out any run-out like that when on the road. If the wheel weight balance is out you will feel it but a little bit of wheel or tyre run-out has almost no noticeable effect.

The way i look at it is if the rims are supplied or need spigot rings to fit, then they are there for a reason, so fit them.

I'm not saying they aren't needed. I'm just saying they aren't vital and you can get by without them as long as you know what you are doing.

Agreed, if you use the correct nuts for the rims it will bring them centre, but the correct spigot rings aline them up with out the need for crossed fingers, so if they need them fit them is my out look on it.they are not that dear, i have a set that i am refurbing for my black and gold Mk 2 that needed them, measuered up straightbonto the bay of E ,couple of £'s and through thr door, but what i will say is also make sure that the right nuts are fitted also otherwise it can ride egg shaped or cause unwanted damage to the rims.

So for dumbasses...what's the difference between spigot rings and spacers?

[Mazda Mender]

A spacer is like a big washer if you like, colin as posted some up that he as just bought which can range to any size/thickness and just makes the rim sit further out..

Spigot rings fit inside the rim so that they will allow after market rims to line up to the hub correct...
