I'm replacing the bearings all round as part of my restoration and was wondering if it's possible to fill, drill and tap the lug holes on the hubs to a 5 stud pattern?
I know people fill and drill wheels for a 4 stud fitting, but was wondering if doing the hubs is possible?
Will they have to be filled? Or could the just be drilled and re-tapped?

Speak to Rav, he does it all the time, when not drifting or grouting :)

Depends on the hubs, some are a constant thickness, others are thinned in between holes.

You could probably drill a solid hub to 5x100 quite easily, keeping one of the existing holes. You would have to see where the other holes land, but I think they'd be ok.

Very much doubt there's enough width to safely go to 5x120mm for bmw wheels though.
cheers,

Drilling discs is no biggie, and would only need doing bow and then. The holes in discs are usually a fair bit bigger than the wheel studs too, so they wouldn't even need to be that accurate. Assuming you're still using e30 disks they'll still centralise on the hub. Chances are there would be a vag disc which would fit anyway.

I'll have to look into it a bit further and see if there's enough meat for 5x120 if not I'll go down the wheel route.

It's been looked at before, there isn't enough material to safely drill a 5x120 pattern. If it was that easy, there would be a lot more 5 stud E30s!

Yes.

But you might struggle with the hub size on 4x108 wheels.

What exactly do you mean woth the hub size? Not enough meat left on it do drill them safely?

Its either that or redrill the wheels which im less keen on.

I thought about this before but as said above the 5 x 120 is a larger diameter so there's not enough room.
But I was thinking could a machine shop could make 5 x 120 hubs to fit an e30? Maybe it would be too costly?

The front hubs would be easy enough to make but the rears would be harder with the hub having the spines for the drive shaft in, to make these splines in a hardened material would be costly and at a guess much more expensive than using the compact rear arms and hubs.

Turk I think, although I've not seen them for sale since.
There is a solution from 300mm.de iirc, to use the E36 hubs on the 4 stud E30 strut. As with any thing like this, the kit isn't cheap.

The 1 series uses the same size rear wheel bearing as the E30. The 1 series rear hubs can be (and have been) used in an E30 trailing arm and aren't overly expensive. I'm not sure on what brake setup is used though.

A lot.

Got to admit, I don't really understand swapping to 5 stud unless doing it properly with e30 m3 gear
