As title got some 15mm rear hubcentric spacers but they won't sit flush because of the depth of the the 57.1mm part of the brake disc.

I knew this could happen with 10mm hubcentric but thought these would fit. :angry:
I know people do run 10mm spacers on the rear, are these just flat spacers then?
Would a 15mm flat spacer still allow the wheel to mount on the lip?
-
cant you just file the spacer down abit to fit? if the rest of the bit that goes over the slip is a nice fit still can you just file or grind the inside rear edge out a little bit?
-
Wouldn't be able to file it but would be possible to machine out but don't have access to that type of equipment. I would have thought machining it deeper though would weaken the lip which the wheel sits on.
-
Try sending dom069 a pm as he had the same problem with the spacers on his old mk3

Wheel doesn't sit on anything. It's bolted to a face.
Have you tried putting wheel on with spacer and bolted it up to see if it sits flat?
-
You need to chamfer the back of the spacer to allow the profile of the hub to enter the spacer,this will not weaken the spacer at all as you only need to take approx 5mm out :wink:
-
Surely the whole point of buying vehicle specific hubcentric spacers is that they sit flush with no fannying about :undecided:
Wouldn't be very happy if I bought them then had to go get them machined!
-
Cheapest ones he found I bet :lipsrsealed:
Get what you pay for

The wheel sits on the hub locating ring and then is bolted to the face. Think the point of hubcentric spacers is they centre correctly and the weight is transfered to the hub and not through the bolts.
Not put the wheel on but it definitely won't sit flush as shown in the picture.

This would work but is something which would need to be done on a lathe which I don't have.
-
Doesn't need to be 100% exact to be fair.
I would have a crack with a dremel or even just by hand with an emery cloth.

Coming from Yorkshire whilst I can be a tight arse on occasions I don't think this is the issue here. :wink:
The problem here is the depth of part of the hub/disc shown in the photo bellow. I've not measured it but it is greater than 15mm which is why it is causing problems.

This is something which others have also experienced by the look of it.

Would appear to be more an issue with the design of the mk3 rear hub than the spacers. I spoke to two companies before I bought these one of them Venom who said they don't supply 10mm hubcentric for the mk3 as they have had this issue, I just thought that 15mm would give enough clearance.
I know people do run 10mm spacers on the rear, ess three I know does, therefore I am assuming these must be the flat type.
-
Sorry I see the problem now.
Hubcentric spacers are made so that's it's easier to put the wheel on. The bolts keep the wheel central on the hub.
Send them back and just get a 15mm spacer not hubcentric.
I have 5mm each side on the rear

Nope, mine are hubcentric.
Rear discs vary in the amount of metal on the spigot section...some hubcentric spacers fit, some don't.
My 10mm spacers are Eibach or H&R...and neither fit these discs, but they did the last ones I had fitted.
I filed off the upstand part of the 10mm spacer, so I kept the conical spigot locator, and use the spigot on the disc to locate the wheel.
This is the case on both the H&R and Eibach 10mm spacers...actually, if you tightened the wheel up it would shear off the offending bit, I just tidied up what was left with a file!
My 15mm spacers fit no problem IIRC.
The better way to do the job is to use rear beam spacers between the stub axle and beam, as this doesn't put higher load on the bearings.
I am running 10mm rear beam spacers...and currently 10mm wheel spacers too, until I've finished playing with tyre widths etc and I will most likely go with 20mm rear beam spacers.

I have 5mm each side on the rear
The bolts take provide clamping load, the friction of the wheel to hub hold it there...but the spigot on the hub located it centrally.
So if you don't run hubcentric spacers, and aren't using the original spigot - or that of a hubcentric spacer - you run the risk of slight missalignment leading to vibration issues.
At 5mm, flat spacers are fine - there is enough original spigot left to locate the wheel.
At 8m, it's barely enough...but if you are careful, they are usually OK.
By 10mm, I'd say you really need some form of hubcentric type to ensure no alignment issues.
It is very easy to missalign a wheel with 10mm spacers (or greater) if they aren't hubcentric.
A 5 x 100mm set up is pretty good at centring the wheel, but it's the chamfer on the bottom of the spigot that ensures the wheel is sitting central.
-
Cheers for the advise, I will try tightening them up and see if they do shear any metal off and can then be filed.
Just got brand new discs and I am sure the spigot section is larger on these than the last ones.
-
Right the good news is I've tightened the wheel up and they are now flush............the bad news is the wheel spacer hub spigot/hub locating ring has sheared off! :laugh:
To be honest I don't think machining the internal 57.1 part deeper would have worked either. Difficult to explain but as both the internal and external spigot part are 57.1 there is not a lot of metal to go at....either that or cheap crap after all.
Going to have to get some 20mm ones and hope they don't rub the arches.
-
I've just come up against the same problem. :angry:

Don't listen to me :grin:
I've got 14mm hubcentric on the front and 5mm on the rear.
But on both 14mm hubcentric and 5mm spacer they have been machined on the inside.
Are yours not machined at all?
-
Machined like this. Not mine but mine are the same.

Its exactly the same issue as Kahuna had, I've just bought a pair of 15mm hubcentric spacers to go on the rear and the spigot on the disc is too deep meaning the spacer doesnt sit right back against the face. Im thinking maybe putting some 3/5mm flat spacers behind them to pack out the unwanted tolerence.
-
I must be lucky with mine.
Sounds like a easier option
-
So do you mean the spacers haven't got a large enough chamfer to sit over the disc chamfer?
-
You need to chamfer the back of the spacer to allow the profile of the hub to enter the spacer,this will not weaken the spacer at all as you only need to take approx 5mm out :wink:
+1, I think 5 mm is more than enough
Edit.
Fck me you never squeeze up something like a hub spacer :shocked:
If it don't fit flat by hand dont stick it on
Non hub centric spacers or HC spacers with poor location spigot into the wheel are full of fail
-
Im not big on the idea of trying to force it through the front lip either, at the end of the day the locating lip is there for a reason... Not to be sheared off from over tightening.
-
So do you mean the spacers haven't got a large enough chamfer to sit over the disc chamfer?
The wheel centre to spacer face locate perfectly, its the disc spigot to the rear of the spacer that isn't deep enough. The bore is spot on, the actual chamfer angle sits correctly. Its as if the spacers should have been 20mm thick.
-
Its like ESS three says. It depends on the disk. Some are longer than others.
I think I'm lucky as my 14mm hubcentric spacer fits just fine.
Like you say, it might be easier to put a 3mm spacer on first.
-
Im thinking maybe 3mm flat spacer first or get some 18/20mm spacers to go on instead and stick the 15mm spacers on the front or like Glen mentions , fabricate some stub axle spacers and skip over all these issues.
-
Wouldn't you have abs sensor problems if you spaced the stub 18/20mm
Saying that if you make the spacers out of aluminium you can relocate the sensor.
-
Surely it wouldn't be affected seeing as the sensor is mounted in the base plate of the stub axle and the spacer would be between the plate and the rear beam mounting points ? Need to source some nice blocks of ally first though.
-
Yes sorry your right. I recently done my rear shims and thought the sensor was mounted on the beam. God knows why :laugh:
Its late I'm going bed :grin:
-
Yep, ive decided il be making some spacer plates at work instead. Il be able to keep my locking wheel bolts as well as having no faffing around with chamfers and longer wheel bolts etc.

Id stay away from Aluminium and use BMS or P20

BMS will rust and P20 is tool steel, which is pre-hardened and wont exactly be that easy to machine and drill, I would use some 304 stainless, pretty cheap, easy to machine and doesn't rust.
Aluminium would be ok for this application as theres no real stress on the spacer plate itself once everything is all bolted up together, my first choice would still be the stainless tho :wink:
-
I cant see how using aluminium could be an issue when you consider that virtually all the off the shelf wheel spacers are made from machined solid blocks of aluminium.

I was thinking the same thing :huh: I've got a bit of blue plastic and that's ok.
