I have some 8Jx18 ET20 alloys with slicks, previously used on a modified e36 race car.
They're no longer of much use and won't fit a standard e36 m3, so I was wondering which beemers they would fit.
Having looked on realoem, I think perhaps e39's / M5, e38 and possible later F10 models?
anyone know specifics?

OP, unless these wheels are running with hubcentric specers or spiogot rings on your E36 they will not fit any E39 as these cars have larger 74mm diameter hub bore, all other modern BMWs run 72.5mm bore.

Off the top of my head 8X18 ET20 should run on E30M3, E28, E24, E32, E38, E34, some minor mod's may be require on some of this list, and does depend on tyres size in some application.

thanks for the info.. i'll check the hub size on my m3 tomorrow - they haven't been run with rings etc. However, I looked at the diameter on the alloys and (from eye reckoning) they would seem to fit a 74mm hub?! Were all e39's 74mm, or just the m5?

I think is was E39s and X5s with the 74mm centre bore, and after that, they switched back to the one-size-fits-all 72.5mm

If your M3 hubs are standard they will be 72.5mm.

All E39's are 74mm.
