I've seen replicas posted in 19x9.5 but is there such thing as an 18x9.5 or 18x10? I would rather keep the stock size but fit a fatter tire on :confused:

Well this doesn't apply to BBS LM-rep, but I have BBS RC 18x10 rear, 285 tire.

Buying an 18 inch BBS lm will look like 17's ...remember the step lip step lip setup will create an illusion of a smaller wheel because of the smaller center...jmho

good point, i never looked at it that way. i just figured why get 19's if they will add rotating mass and potential weight compared to 18's. but a 17" look alike wheel is definately no good.

what is the best offset for our cars? im noob when it comes to this..

if you're thinking of going 18" BBS LM, I would rather keep the 18" stock.

To my knowledge there are no reps for RC. 18" RC looks bigger than 18" BBS LM because it spoke goes all the way to the outer edge.

also for the offset it would be depend on the wheel width, not the diameter.

If you look around the picture other member posted you can get a pretty good idea of certain offset looks like with certain wheel width.

But just go give general overview of the most common offset I've seen

M5 OEM
18x8.0 ET20
18x9.5 ET22



BBS RC (Discontinued)
18x8.5 ET15
18x10. ET25





BBS CH
19x8.5 ET20
19x10. ET20





BBS RS-GT
19x8.5 ET15
19x9.5 ET25
19x10. ET25
(M5 with 19x9.5 all around)



BBS LM
19x8.5 ET17
19x10. ET25





BBS RGR
19x9.0 ET20
19x10. ET25





AC Schnitzer Type III 2 pc
19x8.5 E15
19x9.5 ET21.5




CarGraphic
19x9.0 ET20
19x10. ET20





Hope this give some idea what partcular offset and wheel width looks like on E39 M5 :)

Great wheel pics! But you forgot the most common RG-R color: Diamond Black.

you are correct... :).
In U.S RGR is available in Bright Silver and Diamond Black finish, with Diamond Black is the most common finish .

Its just that I don't have/can't find a pic of Diamond Black RGR on lowered E39 at the good angle.. :D

Cause ultimately when shopping around for wheels the first things that I always look for (off course other than the wheel design itselt) is how far in and out the wheel/tires sits from the fender lip (where ET plays role as well).

now you're talking :D.
Could also post the wheel spec (width and offset as well) ;)

-Sorry, forgot that part. Wouldn't matter anyway, since you're gonna want wider RG-Rs for an M5. 18x8.5 and 18x10 are your width options (8.5 is what we have on the 540iT). I'm not sure what offsets are offered, but I'm sure Tire Rack has that info.
