View Full Version : E30 BBS rims on e21 - What size spacers to run?
jjgbmw323 03-11-2008, 07:02 AM Guys I have these rims. I was told that they are BBS rims that fit the e30 BMW or the A2 VW golf. The offset is 30mm or something. I know the offset on our cars are 13 mm.
I am going to get my existing rims, straightend, restored and polished.
So for the interm I will run these.

Will HR spacers work on the front if they are 8mm? Or do I need 10mm spacers.
I need to space it out to get past the tie rods.
Here is what I was told on the vortex:
The centerbore is 57.1(hubcentric for VW) as long as the hub on your BMW isn't bigger than that, they should work. i have a feeling you should be fine and the specs are the same.
Let me know what you guys think.
jrcook320 03-11-2008, 08:43 AM subtract 13mm from 30mm = 17mm, so you'll be fine with a 15mm spacer.
If the offset is 35mm, then you need to run a 20mm spacer.
Layne 03-11-2008, 09:09 AM They made those for fiats too, so be extre sure the bolt pattern isn't 4x98.
blitzed310 03-11-2008, 10:52 AM Whats wrong with those wheels? Why only run those for the time being? Those wheels are friggin awesome!
wayfast 03-11-2008, 04:31 PM Whats wrong with those wheels? Why only run those for the time being? Those wheels are friggin awesome!the face of the wheel isn't flat... it curves out to give it the lip.. which doesn't look so great when looking at it from an angle

Thanks, they where new old stock in a showroom in Atlanta,
but I prefer the BBS marhle rims on my 323i.
Those are the silver ones on my car, and I am going to get them restored.
I just looked on the Gold set the offset says ET25mm and they are 4 x 100.
If we subtract 13mm from this 25-13 = 12.
If I use an 8 mm spacer is the question. Will this work or do I need a 10 or a 15 mm one.
I am concerned about hitting the tie rods on the front.
undastan 03-31-2008, 12:31 AM If I have a 15 x 6JJ 45 rim, what size of spacer would I need?

IF 45 mm is the offset then subtracting 13 from it = 32mm.
UPDATE on this thread: I have ordered 8 mm spacers for my gold rims, hopefully the fronts will clear the tie rods with those spacers.
undastan 03-31-2008, 03:07 PM thats a pretty big spacer.... is there a way i could mock it up to see how it would look/fit?
peteymedic 03-31-2008, 04:44 PM the paint on your fender in the pic looks Sweeeet!!!

Bolt it on and see what you need, look at the front tie rods...
the paint on your fender in the pic looks Sweeeet!!!
Thanks,
thats an aftermarket fender that we painted to see if we liked the color,
I had the whole car resprayed the original color = iberscrott = spanish red.
undastan 03-31-2008, 06:53 PM I have bolted on the rim and it does hit the tie rod.... I used a stack of cd's/dvd to determine that I may need a 20mm spacer.... if 15 cd/dvd's = 20mm...(can someone verify?) its the best I could do as a mock up.. gotta use what u have, right.
EricDJ 03-31-2008, 07:32 PM Are these 15x7? Some 15x7's will fit at 17mm, they did on some TSW's I had before.

Sorry I didn't see this when you first posted it...
You should AVOID 8mm spacers at all costs if they are not CLEARLY billed as hub centric. If they are just a flat piece of metal used to space out the wheel then you are running some safety risks. The wheels mate to the hub (that 57.1mm portion coming out from the hub specifically) and that helps distribute the weight of the car to the wheel in a safer fashion. But shortening this 'lip' with a non-hub-centric spacer, you are putting more stress on the lugs/bolts/etc holding the wheels to the hubs. Most companies do not make hub centric spacers smaller than 10mm. And that is ALSO where the prices tend to jump up a bit since they require a bit more engineering to initially design and machine (...at least I imagine this is why they are priced higher...).
Anyway, if the 8mm ones work for you to get the car on the road, do it. But be aware that with any spacers more than about 10mm you will need longer lug bolts at the least, if not swapping out to a full lug not conversion.

Doug thanks, these are Hubcentric HR spacers that are 8 mm and have the longer lugs with them. They seem to be off excellent quality and where use on a MK II VW, I got them on the vortex. They are so i can run the gold rims without hitting the tie rods. I will post pics of them tommorow.
The silver marhle rims are going to get restored. My tires are also needing replacement after 1994 and 15 years in the shop.
todor 04-01-2008, 04:05 AM FWIW, 57.1 is the correct bore size for almost all BMWs, definitely including the E21.
I've read some info on spacers and the consensus seems to be that as long as they are hub-centric, they're not a problem. But definitely stay away from the flat (non-hub-centric) ones.

Here are the ones that I got.
H&R 8mm (4x100) Wheel Spacers
[16234571] $49.99
H&R 8mm (4x100) Wheel Spacers
These precision engineered, aluminum/magnesium alloy hard-anodized wheel spacers are hub-centric and up to 70% lighter than standard steel spacers. Kit includes one pair of spacers, so two kits would be needed for the entire vehicle. Increase track 8mm each side (16mm total) with this kit.

and I have the longer lug nuts to go with it:

mxl556 04-01-2008, 11:41 AM Joe,
These are not hubcentric and they are tricky to install and have the wheel centered on the hub. They are OK as temporary solution, I believe that's what you got them for.
Anyway make sure you have the wheel centered otherwise you gonna have shimmy that shakes the whole car...Ask me how I know.

blitzed310 04-01-2008, 11:57 AM Joe are you sure you understand what hub centric means in respect to a spacer? The ones you posted are not.
These are:
http://www.zeckhausen.com/images/Product_icons/spacers_big.jpg
These spacers have a female to male adapter. The spacers center themselves on the E21 hub (centerbore) and then extend that centerbore to the wheel. This is what allows the wheel to sit on the hub with no lugs without falling off.
Here are the ones you posted next to a hub centric:

Layne 04-01-2008, 12:24 PM FWIW, 57.1 is the correct bore size for almost all BMWs, definitely including the E21.
If I may be an ass and correct you unnecesarily, "almost all" BMW's (dozens and dozens of different models) are 5 lug and therefore 72.5mm centerbore. The 3 major models (e10,e21,e30) and a few rare ones that have 4 lugs do all have a 57.1 bore, but in no way comprise "almost all". :D

Ah yes, you're right. I had gotten confused. Yeah, most Bimmers actually seem to have a 72.5 bore - that's the one I was thinking of. But I remember that my E21 has a 57.1 so I assumed that that was the common number. I also know that E39s are weird and have a 74.1mm bore. Anyway, the important thing is that 57.1 is correct for E21s.

Ok. So who makes those spacers that are hub centric? I thought the HR ones where but apparently you need the extented part to hold the rims on the spacers.
todor 04-01-2008, 07:13 PM Well I'm sure H&R makes hub-centric spacers too, you just have to find the right ones. And as someone already pointed out, spacers less than 1cm thick are usually not made hub-centric because they may not have enough metal to even fit the original hub's "ring" that sticks out, nor enough strength to provide such a ring of their own.
I see that the description of those H&Rs does say hubcentric, but they're probably referring to the fact that the spacer fits snugly around the ring of the hub... not that the rim would fit around anything on the spacer. So the bottom line is, you gotta look at pics and make sure the spacers have that ring sticking out of them. That's pretty much the only way that the rim can be centered correctly on the hub. Otherwise it'll always be slightly off in some direction and cause vibration and/or suspension damage in the long run.
uberpanzer 04-01-2008, 07:55 PM Yup. H&R 10mm and up spacers are hub centric.
.....damn it....why didn't I see this thread before you bought those. :(

Ok. I am going to either sell the 8mm for the 10 hubcentric, or wing it for a month when I get the silver ones restored.
mxl556 04-02-2008, 11:53 AM I'd just get the wheels restored, it takes 2 days. Why would you want to pay 50% of the cost of the wheel restoration for a spacers you will need for a month.? I paid about $200 for my 20mm spacers and bolts, but they usually sell for more

Thats how Joe does things.
EricDJ 04-02-2008, 03:11 PM If he uses spacers he can sell the spacers off and the wheels on the vortex.
Jester323 04-02-2008, 05:49 PM If you are very carefull to tighten all four bolts down at the same rate, you should be able to get it very close since the heads of the bolts are tapered, they help to keep the wheel centered. I wouldn't tighten them down more than one turn at a time in an X pattern once the tapered ends of the bolts start making contact with the wheel. Also, keep your speed down and you should be okay for a month or so. But if you start getting any vibrations from them you'll need to reseat the offending wheel before driving on them for any length of time, and you may want to consider buying new lug bolts afterwards, as the vibrations can cause a lot of shear stress on them.
jjgbmw323 04-02-2008, 06:31 PM Thats how Joe does things.
Its just so I can get the rims restored.
It maybe a week or so, and I want the car mobile.
I have nothing else to put on it in the meantime.
Then I am going to sell the spacers on vortex. I am giving my freind in VT the gold set, and we are going to get the correct hubcentric 10mm HR spacers and bolts.
Jester - these are the longer bolts made for the 8 mm spacers...do I still have to worry about them vibrating loose?
twenty02vnz 05-20-2008, 04:57 PM Do I need modification/spacers or what so ever to put? And what size of tire do you recomend? BTW, car is not for track.
Thanks,

VacMan 05-20-2008, 05:08 PM Do I need modification/spacers or what so ever to put? And what size of tire do you recomend? BTW, car is not for track.
Thanks,
- vinzI'm guessing OS 15 is +15 offset, so you should be fine running those as long as they're hubcentric. I believe the stock size is 185/70/13.
