what is the measurement of the hubcentric rings for Rota Slipstreams for a civic?
56.1mm is the I.D. what is the O.D. of the ring?

 

Good question.
I just cleaned and rotated my slips on our 97 ex coupe a few weeks ago and noticed I didn't have any rings. (car came with the slips) But I didn't pay enough attention to see if they were even needed when mounting them. *slaps forhead* I was in a hurry.

I googled a bit and found this for sale ad.
Flat Blat 16x7 Rota Slipstreams 56.1mm centerbore.
I guess they can vary from different wheel sizes but I'm not going to worry about rings for now. They run fine. So maybe mine are the proper size from Rota :D

I will look at them on the next rotation though.

 

any one else? have them on their 15inch slips?

 

the size is printed on the box's sticker

You can go to discount tire and they can tell you the wheel size AND sell you a set too.
I want to say its like 67mm...but its specific so dont go on what I cant remember...

 

67.1 outside diameter and 56.1 inside diameter.
