is there any modifications needed to fit the wheels at all.
e.g. will i need spacers ?
and does anyone know the offest for these wheels ?

No modification required to fit them provided you get the correct 4x108 pcd as they are also in 4x100 from memory.

You will need to get tapered wheel nuts to suit the rims.

The offset to go for is the ET33, (they are also available in 35 and 38?)

You may find they just rub the chasis rails on full lock..
They will also foul the strut if you run too wide a tyre.

For best fitment, run a small spacer on the front (illegal, but so is a tyre that contacts the chassis)

So in answer to your question, no modifications needed... might need spacers...ET33,ET35,ET38

If the offset is not ideal you can always get the offest altered to whatever you want - or even replace the 5.5" or 6" with a 7" rim

I think Sean on here had his done for around the $75 ea.

i would like to know more about the 7 inch rim change is that just the center removed and re welded to a wider rim? If so a member of our rs club had some made for his anglia 7x13,s from std 13 inch wheels he said $400 in all.

There are 3 ways you can have your steel wheels 'widened' or changed.

Banded wheels - these are illegal in oz (non ADR compliant - must have maximum of one continus weld) were they cut your wheel in half and insert a 'band' of the required thickness.. common in the UK.

Widened wheels, where a rim is cut close to the mounting face and then welded onto another rim which is cut further out from the mounting face, effectively widening the rim, This IS legal but not very common, an old hot rodders trick.

Changing the outer band of rim. The centre is removed from the outer band which is then changed, either for offset, width or both. This is the most common and will cost around $130 rim depending on where you go/size.

Here is an example - http://www.raceengineering.com.au/wheels.htm

ohh right, thanks guys..
so they came in both 108 and 110 pcd ..
hmmm will have to check when i go looking for them
how much will a set of these set me back ?
thanks guys

The CB is larger on Saab rims, this is often overlooked, but is vital for proper fitment, safety and wheel balance.

How do they change offset and get it true? eg; you were to get a Saab rim of ET39 and want to just change offset to ET12. I know they remove and reweld the centre, but how do they get it true so the wheel has zero 'wobble' when welded back? I ask as I would like to have a go at changing the offset only on steelies. How do the pro's do it?

They will fit the wheel into a jig and and check on a lathe to ensure the centre is true.

For a backyard job.....

We did it years ago when we changed the offset on a Dyna truck rim for a mud racer. The center of the rim was by drilling out along the spot welds, which sllowed us to knock out the center section. It took some work and heat on the outer! We then supported the center section where we wanted it inside the outer rim. We checked using a short spirit level across the center and also a longer one across the top of the outer rim. It was tacked in, then we rechecked both sides by turning the rim over. Once we were happy, that it was all level and square, the centre was fully welded in and the original plug welds were filled. We never had the rim on a balancer as we fitted rice paddy tyres but from all indications it was straight and true. I guess you could also make up a jig however we wanted something quick simple and cheap.
About as good as you'll get for a backyard operation without a proper lathe or balancer to check.

my old mans a boiler maker and has done many wide steels, yes back in the day they use 8 rims to make 4, use the flats in the bottom of the rim and weld together.

this will gain a maximum of about 1 ich so not ideal really, but as far as getting the centres true when replacing with a wider rim on the old centre.

yes they usally do them in a lathelathe, but also his done them on a hub, with a dail indicator witch is well within tollerance.
