Default BBS RIMS SIZES

Can you get the old school style BBS spoked rims in 16X7, with 65mm B/S?
I see them alot on 928's, but I never see that size.
I would like to run 4 same sized rims on my 85.

I have some... Not sure if they are 16 or 15. I think 16. But they have some cracks in the rears. The rears are larger than the fronts however.

-edit- and they are 15s. Just found some pictures of them.

Sure, BBS RS three piece 16x7 with 225/50R 16s. The front wheel has more offset then the rears, gives the rears a more deep dish look. Not sure what the offsets are specifically though.

I will have at least 2 BBS old style 3 piece spoked rims in 8J x 16 et 23 off one of my 928's ( 84 euro) in a couple of weeks if you are interested. PM me your email address and i'll send more info.

Plug the numbers in here : http://www.1010tires.com/Tools/Wheel-Offset-Calculator - there is a big difference! Over 1 1/2 " more clearance on inside, and they extend over 1 1/2 " more on outside.

Et 23 is early offset, pre 1989 911's and pre 1987 944's. Et 65 is smack on 928 offset as well as other late offset cars.

ET is offfset -
The number is the distance from the centerline of the wheel to the back surface of the hub.
So if you have a 7 inch rim, and 65mm offset, the hub is half of 7 ( 2 1/2 * 25.4 = 89mm - 65mm ) which is 24mm from the centerline.
The inside edge of the rim is therefore 24 + 89 = 113 mm ( about 4 1/2 inches) ) from the front surface of the hub.
A et23 would be 89 - 23 = 66mm from the centerline, so the inside edge of the rim would be 89 + 66, which is 6 inches from the front surface of the hub.
This does not take into account the width of the mounted tire, of course.

Hope this helps, not confuses
