Chris - I've searched all of my manuals and looked at several spare wheels I have laying around - can't find any mention of the offset anywhere. Sorry! Might have to work out how to measure it!!

You will need about 10-15mm thick plates if you use some bespoke wheel studs that push in the back, otherwise your thread engaugement will probably determine how thick the plate needs to be. What you really want is the offset of the wheel that is going on after the conversion (99 or 900?) and its width (4.5, 5, 5.5) to check clearance etc.

You will need to measure off a straight edge front the rear of the rim to the fixing face and work out where the rim centre lies.

PLEASE READ.

After further talks with the father in law I think Ive managed to work out the offset on a 96 wheel.
Width = 125mm
Backspace = 108mm
Outside of rim to centre of wheel = 62.5mm
Offset = 46mm

So I think that a 5.5J wheel with a 35-40mm offset plus a 20mm adaptor would do the job,someone tell me I am right or wrong because if this works it opens up a whole new world of wheels that are cheaper and more readily available.
Please feel free to comment as I am not an engineer.

I know this is a minefield but based on your numbers I'd have said you want a wheel with 26mm offset to add to your 20mm adaptor to get it back to the 46mm you've measured.

Hi Chris,
Hope all is well - fitted your old towbar to the Blue car a few weeks ago - it now has a Mountain Bike rack sticking out the back quite a lot of the time!
Like the sound of adaptors. Something important to bear in mind (I think!) is that when you bolt the wheel to the car there is a lip on the hub that fits inside the wheel and centres it. The adaptors would need to mimic this for the wheels to centre properly. I only mention this because I vaguely recollect spacers being available in the past to widen the track that had problems in this department.
Also someone mentioned the VW stud pattern... This would be my top choice as the older VW five stud pattern would be nicely in keeping with the five stud SAAB pattern while opening up a huge choice of nice wheels...
Cheers
Gareth

20mm was a bit of a guess on my part Derek, my father in law said about 25mm so you are probably right, depends on the offset of the chosen wheel.

Hi gareth, good to hear from you again. This little project is (I hope)going to save me some money as I do not want to spend nearly £850 on a set of minilites. If it works it will allow a lot more wheels to be used such as VW, Ford, Vauxhall,and a few others. My (No 1) father in law can get the things made for me but will probably take a bit of time,he reckons he can do these for quite a lot of wheels as long as certain other things measure up.
I dont know wether he will do any more after mine, it depends on the company that now owns his business but when mine are done I will let you(and everyone else) know.

Adding a spacer reduces the offset. Lower offset = wider track.
Me and two other guys here from Denmark bought a set each from www.manton.se
I don't know how thick they are, but they can be fitted with the original bolts for the steel wheel.
They allow you to mount the old 99/90/900 wheels. I have a set of 5,5" ronal silverspoke (Minilite) which i fitted with 185/65-15 tires. These fit perfectly on the front, but the rear wings/fenders need to be moved outward a bit to avoid scraping when cornering or carrying passengers in the rear.
One of my friends have a bit narrower tires fitted. 175/70-15 I think. These fit perfectly without scraping.
Iíll measure the thickness of the spacer tomorrow.

Thanks Mads,thats the size I was thiinking of going for(175x65x15) which is the BMW Mini size,lots of choice there,and reasonably priced.
Just looked at Mantons site and they would be about £200 plus, inc post.

New Mini size is 175/65/15. Just about OK for 4 1/2 but not listed by the tyre companies, but doubt if there have been any 15 x 4 1/2 wheels for years!, and fine for 5 and 5 1/2".

They cost me ~2500DKR which is about £280 today. This is including postage and everything. I don't know how many sets they have made for the 96. I'm quite sure they only make them on order, so the 3 sets we ordered would not give us any special discount. But I think they have made quite a few for Swedish SAAB 96 owners also, so they might have some in stock.
