I have a set of 18" Fox FX004 with 245/40/18 tyres on that were a winter set on a 09 TTS.
Can I adapt these Alloys to fit my 28i z4 for a winter set ( non staggered). My Fox alloys came with plastic adaptor for audi.
Fx004 looks like 15MM hole for wheel bolts. The bore of the FX004 looks like 73MM ish

If these can be adapted is it safe?

Audi is ET45 5x112 M14 bore 57.1
BMW is ET42 5x120 M12 bore 72.6
 
The only way it would be safe would be to have 5x120 spacer with 5x 112 studs or threads.
Not sure about the offsets? You would need 15mm thick spacers at least i would imagine.

But you couldn't re drill the wheel.
 
That's a lot of effort for those wheels.

Sell them and get a set that fit properly.
 
you can get ttrs copies in 5x120 PCD 18-20", they aim them at the T5 market BK Racing do a nice version in 18", also wolfrace (not so nice)
