i have searched and couldnt find a staright answer, i have a set of 15inch rota slipstreams on my 95 civic and was wondering what size hubcentric rings i would need to get.

 

Get rings that are 56.1mm inner diameter and 67mm outer diameter. Should fit nice 'n snug.

 

I forgot what size the centerbore of those wheels are but you can measure that easily with a digital caliper or a ruler. Figure that out in mm and find the correct one that fits that and is hub centric to the cars hub bore which is a 56.1mm Any wheel/tire shop should be able to provide some cheap plastic ones which work fine.

 

The hub on the car is actually 56mm. Which is why the OEM wheels have a bore of 56.1mm - so they just fit over the hub, for a snug fit.
Rota Slips have a bore of 67.1mm, which is why I suggested 56.1mm ID and 67mm OD.

 

^^^^^It wasn't me is absolutly correct. I just got some hub centrics for my Rotas.
