Hubcentric Rings for Lorinser Wheels
After installing my 19" LM6's and me returning to say they're not in balance, the shop that installed them told me I likely need hubcentric rings. Can anyone edumacate me on exactly what it is that I need wrt ring size and spacing? And where I might find it?

Yo foo, it'z 'cuase yo rims on da right or starburst side are azz-backwards!
LOL
For real though, I've never heard of such a thing with regard to wheels. Does he mean spacer rings? Though if you needed those, I'd imagine they would have installed them at the mounting shop. If the wheels are out of balance or mounted incorrectly, then I'm not sure what good a ring would do anyway.

The Lorinser LM6 application on the R230 SL-Class does require specialized Lorinser mounting hardware.
The way that the LM6 is engineered, it has a base offset of ET38 and a centerbore which is larger than the Mercedes-Benz hub. When using this wheel on a chassis that takes ET38, the mounting kit includes 5 lug bolts and a hubcentric ring. For lower offset chassis, like your R230 SL-Class, it uses a special hubcentric spacer which has a raised portion that locks into the wheel on one side, and is hubcentric to the car on the other, as well as longer length lug bolts. If you are running the 8.5x19 front and 9.5x19 rear setup, you can go with either the 7mm kit which makes the offset ET31, or the more aggressive 12mm kit which makes the offset ET26. There is also a different 19" setup available for the R230 which is 8.5x19 front and 11x19 rear. This setup uses the 12mm mounting kit in the front, and the 7mm mounting kit in the rear.
In the Bay Area, you can get the required hardware @ Kartoyz Audio & Accessories in San Jose.

FYI, here's the reply I just received from Lorinser, backs up Ken's info...
Tires you can use the following sizes:
285/30
The tire size on the rear axle which you have (295/30 19) is not approved and not allowed. So this cuold be the problem you actually have!

For SL500 R230 / 2005 you could use the following sizes:
Front: 8,5x19 offset 31 or 8,5x19 offset 26
The basic wheel LM6 8,5x19 is offset 38 so you need adapter as following:
For 8,5x19 offset 31: Adapter-Set 7mm M14
For 8,5x19 offset 26: Adapter-Set 12mm M14
Tires you can use the following sizes:
255/35 or 245/35
Rear:
9,5x19 offset 31 or 9,5x19 offset 26
The basic wheel LM6 8,5x19 is offset 38 so you need adapter as following:
For 8,5x19 offset 31: Adapter-Set 7mm M14
For 8,5x19 offset 26: Adapter-Set 12mm M14
Tires you can use the following sizes:
255/35 or 245/35
Rear:
9,5x19 offset 31 or 9,5x19 offset 26
The basic wheel LM6 9,5x19 is offset 38 so you need adapter as following:
For 8,5x19 offset 31: Adapter-Set 7mm M14
For 8,5x19 offset 26: Adapter-Set 12mm M14
For 8,5x19 offset 31: Adapter-Set 7mm M14
For 8,5x19 offset 26: Adapter-Set 12mm M14

Actually, you won't be getting rings if the wheels are for an R230 SL-Class. The rings are only used for high offset applications such as the S-Class or CL-Class. The mounting kits will include the specialized hubcentric spacer which I described earlier in this thread together with the required 5 longer length lug bolts. As my colleague Michael Franz from my German office stated, this is the setup you will need. Also, regarding the 295 tire width in the rear, this does not carry the TUV approval with the 9.5" width rear wheel. It is however good to go if you happen to have the 11" width rear wheels. The $75 per corner price you have is actually quite a good deal as the mounting hardware carries a MSRP of $119 per corner.

Ken, these are the the spacers you're mentioning as the correct application for my situation, right?

Those are the spacers needed if you are running 8.5x19 front and 11x19 rear. However, it appears that the necessary lug bolts are not included by looking at the images. If you are running 8.5x19 & 9.5x19 you should run either 7mm on all 4 corners, or 12mm on all 4 corners. In addition to being the proper length, I believe that the radius of the ball portion on Lorinser lug bolts is not standard. It is for this reason that lug bolts are included even on applications that do not require a spacer and use only rings. As the Lorinser lug bolts are only available in the mounting kits and not available separately, you would be better off just purchasing the proper hardware for your wheels. The mounting kit includes the spacer, 5 lug bolts, 3 smaller bolts which lock the spacer into the back of the Lorinser wheel, and valve stem. Image shows the 7mm kit on the left, and 12mm kit on the right.

Well, I bought the wheels second-hand and had them installed at a general mechanic shop that's in SOMA on my way to work. The owner doesn't profess to have knowledge particular to tuner wheels and such, so it's not a matter of his dishonesty or incompetence. He balanced and mounted my wheels. When I said the car still seemed unbalanced, he said it's probably because I need hubcentrics. So really, he's right about it all. Only thing is that he wasn't aware that the hubcentrics I need are actually machined aluminum and proprietary, which I can't really fault him for. It's a learning experience for him as much as it is me.

lots of cars
I have one spare Lorinser 7mm spacer, I also know a shop that can custom make these spacer for you. I've always used ball seat bolts on Lorinser wheels with out any issues.

Try reaching out to Ron's tire and wheel in N.Hollywood, they were importing Lorinser the past few years and might have the correct adapter kits for your wheels to fit your car.
Hope this helps.
