Hi all wise car enthusiasts ! Old story , old Vauxhalls have a funny PCD , offering wheels options from erm.... other old Vauxhalls - hillman imps and well beetles if you don't mine a ropey fit lol so , is it possible , has anyone re drilled Vauxhall hubs to fit 4 x 108 PCD  Before I go about pulling out half shafts etc is would be handy if someone could fill me in before I get my hands dirty ! Thanks in adance |

anything is possible, got a picture of the drive flange? what is the current pattern and offset?
not sure I would choose 108mm to be honest, 100mm would be better as you have the whole VW/bmw and many Japanese cars to take wheels from, 108 is ford if its a deep offset or peugeot if its shallow.

I'll show the process when I do it - I have 2 sets of slot mags 108 PCD hence why I'm going for that , currently 100mm already fits on there ( not perfectly) thanks for the post ! |

Funny? 4" isn't all that funny for the time :-) . This is a photo from the back, this is an OHC hub for reference. Would re-drilling 4mm further out be a bit close to the edge? On the one hand the hub starts getting thinner towards the edge because of the chamfer, on the other hand you can see the existing stud seat is already recessed into the hub in the standard location Not something I know anything about, just in case the photo helps anyone decide.  |

From a little research it's only a few Vauxhalls and hill man imps that have this stud pattern - I find it strange that's the only cars that have this Pcd - I guess it was to maintain parts bought from Vauxhall - who knows !
The image is hugely helpful thanks - clearly its not the right way to go or particularly safe , redrilling the hubs. I have heard many people have done this before but from seeing the chamfer on the back this doesn't look like a good idea.
I have another HB coming - I'm going to pull off a half shaft and front hub and see what can be done . It maybe possible to turn off the flange all tegether , turn a new flange ( thicker too ) that is a tight fit and weld it . I'm going to keep looking into it - the wheels you can have for a viva I think is quite limited , modifying it to take ford wheels would giive loads more options . If I can do it properly I will - if any doubt on safety I'll just have to live with the wheels available

IIRC Pop Brown's sell alloy viva hubs for Ford fitment
|
| |
Atmo V8 Power . No slicks , No gas + No bits missing . Doing it in style.
Austin A35van, very different------- but still doing it in style, going to be a funmoble

pretty sure some of the f*rd front hubs go on to the Viva stub axle ok with a spacer for the rear bearing, might be worth looking at that

I am pretty sure Mini PCD is the same as an Imp. I have had imp wheels on my Mini before. Most aftermarket Mini wheels, especially the bigger 12 and 13" ones have offsets that make them stick out a bit far so they might be OK for a Viva.
Another option would be to run front wheel drive wheels and use adaptor style spacers to change the PCD but it won't look as good as having deep dish RWD wheels on there.
What about Viva HC wheels, thinking about any other options are Midget wheels the same PCD ?
Morris Minor's are the same as well I think.

  I bought these wheel - which came off a HB viva , I just thought I could put bigger tyres on the backs but they are small because they stick out too far with the hub adaptors . I like how it looks but I'd prefer some proper tyres on the backs , it's a bit hard with the low profiles on |

I know you would end up with extra holes but could you get the wheels re-drilled ? Shame as they do look good on the car.

I thought of that but there are hollows in the castings between the holes on the back - it's not flat , so I wouldn't be able to have countersunk holes - not sure it would be safe as there would be a gap between the back of wheel and the face of the drum where the studs would bass through .

Probably not a good idea then.
I did a search to see what PCD a few cars had and it was mentioned somewhere that Chevettes had different PCD's on them possibly 100mm. Still not 108mm though.

1000s of cars have 4x4inch. Your wasting your time as you will find more or less every wheel in that pcd if you look hard enough (and if you have centre location you can also use wobble boils to fit 4X100PCD wheels on there too.)

Before I go about pulling out half shafts etc is would be handy if someone could fill me in before I get my hands dirty !
