Real question- why?  It's really hard to find 5x120 wheels in sizes you'd need in offsets you can use.  Really hard.

 

4x100 is everywhere, it's super easy to find all kinds of wheels.

 

5x120 in 15 or 16 is difficult.  If you're looking for 17 or 18, yeah, sure, no problem, but anything smaller is tough.  Although some of the steel roundie-round wheels can be had in 15- not quite 5x120, not the right center bore, but you can force them to work.

 

I'm looking at ordering some wheels from the UK custom made to get them to fit properly.

 

But to answer the question, I bought a car that this had already been done on- and they cut everything to ribbons and installed an entire e30 car underneath the body of the 2002.  Over 700 hours, all documented, at a shop.  And it still needed love when it got here.  I'm sure there are easier ways to do it...

I am putting on the style 5 bbs wheels ,17 5 x 120 

[AceAndrew]

Front: 2002tii Struts w/ E12 5-lug hubs/calipers+vented e21 rotors.

 

Rear: Custom

[option 1: weld on material and tap existing existing hub.  As done by Andrew T. and Le Tran] 

[option 2: machine hub from steel{or whatever} billet.]

[option 3: E30 rear end conversion with 5-lug hubs {*see 2002underground for example}]

 

As Dave says, plenty of work and/or money involved.  It's been covered here before if you search.

Ok thanks

Not a big fan of redrilling wheels but would be easy to do with style 5 wheels.

We are slow but steady getting these Rear Trailing Arm kits with 5-lugs ready to go.

 

FRONT: Working with our hub supplier right now to deliver a non-tii and tii front hub 5x120 option, made from 4140 alloy.

 

Maybe we need an OE 2002 Rear 5x10 option as well?

 

Will probably be doing pre-orders for the 5x120 Front Hubs.

Will you be making sealed bearing front hubs in 4x100 bolt pattern?  That would be a terrific upgrade for many of us.  Particularly with big brakes and pad knock-back on the track, which I think is exacerbated by the current hub/bearing.

I'll have to dig into that deeper. It's not off the table! At the very least, we could decrease the hub tolerance to get a tighter bearing fit. 

Side note: got your email! I'll follow up there!
