Wheel spacers do and donts

So the old girl had landed with I thought were mint condition Turbina 14' wheels. They were... just not Alfa Romeo. I'm guessing they came off a BMW or other.

Aside from the obvious (sell them off to a 2002 racer wanna be), what is the advice on fabricating drilled spacers with one set of holes matching the Alfa standard wheel hub and another matching the beautiful and very light but otherwise disfunctional Turbina wheels? How thick would the spacers have to be before tires start rubbing on what is already a very lowered car with hard Koni yellows and no more than 7 cm worth of ground clearance???

If you are saying the PCD of the wheels is non standard Alfa then don't even
think about it!!

OK, maybe I misunderstood....

If you are thinking about using PCD hub adapter spacers, then these will be fine as
long as you have the room to fit them. The smallest hub adapters are 20mm thick,
which is quite a way to space the wheels out....

Try it with one original wheel, space it out 20mm with washers or whatever (not to be driven on..!) lower the car gently and see how much room you have between tyre and wheel arch. Of course the Turbina's may have a different offset to the originals which will affect the amount of space also. The ground clearance is of no consequence.

I hope you like this much better reasoning... :-)

Remember that you have little tyre clearance at the back already. By attempting to run wheels with an incorrect pcd (100mm if they're BMW), and using adaptor spacers to bring the pcd back to the Alfa 108mm , you're already adding to the track width, by the width of the adaptor spacer, before even thinking about wheel offset and tyre width.
So for example if you have 10mm clearance tyre to wing lip, with a known correct offset Alfa wheel running 185 x 70's, and your adaptor spacer is 10mm thick, (and I would think that would be the absolute minimum), then you've immediately got a foul condition between tyre and rear wing.
Don't do it, sell them to a BMW guy and look for some 108mm pcd wheels that you like.

Thx to you all... they're beautiful wheels... such a shame to see them go to a BMW 😢

Photos as promised... any way to confirm what car this belongs to?

Unfortunately not. I can see the size, and a foundry stamp KBA, and can see that they were made by GKN in 1977, and I remember the pattern, but pretty sure they were aftermarket in period, albeit quite similar to some Campagnolo rims.
You can also see the difference in pcd quite plainly, but before you advertise them, you need to measure it accurately, either from the centre of one hole to the centre of one diagonally opposite, or (easier), from the outer edge of one hole to the inner edge of the one opposite. You need to be accurate to a mm, as, (for instance), pre Chevette / Cavalier Mk1 Vauxhall pcd used to be 4" (101.6mm) (Viva, Firenza Hillman Imp etc), but Chevette, Cavalier and after were 100mm, as were BMW four stud (2002, NK 2000, E30 etc), and front wheel drive VW's.

I would list them as particularly suitable for BMW NK and 2002 as they very much suit those cars, and would be quite sought after.

Hope that helps
Steve

Thx. Steve. Think I'll just try them on a buddy's 2002 and take it from there... I know they're not to everyone's taste but I would have loved to see them on the bertone...

they appear to be 40mm offset - so they would need to be spaced out at least 10mm (probably more) to look decent on the alfa. they might clear calipers but not sure of that.

Wheels can be redrilled and steel inserts installed at the correct PCD. I had these guys do it for me from some VW 4x100 wheels to my Alfetta 4x98 wheels for about $150 for the set. They actually didn't use steel inserts for mine as the difference was pretty small, but the normal practice is to do so.

on a bertone you can go to ET 20, with 6J even a little wider. . if the rear axle is centered corrctly. (friend of mine did go to ET 19 with &J , on my racer I even had ET 0 with 7J but that was with rolled lips.
