E30 wheels on 320i?

I have a nice set of 14" E30 bottle-cap wheels with 205/70's on them. Will they fit on my '83 320i?

You can do it b/c they are 4 lug bolt pattern, and I have seen them mounted and it is a cool looking wheel design on the boxy e21. You must buy spacers to help with the fit of the
14" wheels in the wheel wells, and such. Do it. It's a head turner. Here's my "s"

Thanks Unicorn. I'll have to check the offset. Any idea who might sell a spacer for this application?

They should bolt right on. I have used after market wheels off a e21 on a e30 with no spacers. I also have put the bottle caps on a 2002 with no issues. All 3 cars have the 4 x100 pattern.

the only time I have needed spacers is using wheels off a Honda or VW. the front wheel drive cars have a deeper offset so the wheels go to far into the car on a BMW. usually get 1/4 inch spacers off ebay. The non hub centric ones will work but they slide around when your trying to mount the wheel. So you need to tape them into place to keep them centered untill the wheel in mounted and they are locked in place.
Or they make one for BMWs that fit the hub perfectly they are a bit more expensive. Again you only need these for you getting a wheel off a FWD car.

Id be more concerned that the tires are 70 series and may rub if the car is lowere. VS a 60 series tire.

Unicorn,

I finally have time to mount them tomorrow. I'll let you know if they bolt on. Thanks.

bam2002,

Looks like I will need a 5 mm spacer. The wheels fit the hub but tires rub on the control arms on the rear. Haven't checked the front yet. I'm concerned that if I go with the universal spacer that the wheel balance will be off. Has anyone dealt with this problem? Thanks.

For street driving I would go with the Hub centric on the front. You can get vibration in the front end. I have at 55mph.
On the rears you can use the generic. The fronts are sensitive.

Places like Tirerack etc use to sell them, I got a set for a e36. but they were 5 lug.
I got the generics from a Truck and Tire place, and a set off ebay. They work good for Auto crossing, but at a track day I get some vibration at a Track day.

I'm looking at the ones that eibach sells that are hub centric. They are 8mm. I will need to check and see if the tires will rub the fender wells. Those "Bottle cap" E30 wheels will look really nice if they fit.

You do mean the tie rod ends, correct?
I tried it once...offset is all wrong. Hubcentric spacers needed.



The e21 front end design is very sensitive to shimmy!
I tried many wheels with spacers, new tie rod/control arm bushings, anti shimmy kit, etc. and the only thing that stopped the shimmy was a direct bolt on OEM wheel.
Just my 2 cents.

I would think the Bottle caps are direct bolt ons.
I have put them on a 2002 with no spacers needed. And my Baur e21 has a painted set on it now. So actually yes they fit. ( sorry its not at home but away getting rear floors). So I didnt recall the wheels that were on it.

You need spacers.

Call Korman Motors in North Carolina. They can help you with the spacers. Yes, You must get spacers. Figure in the small world, that hundreds of BMW owners have thought of, and succussfully put bottle cap wheels from an e30 to an e21. They all used a spacer.
