Andy T 0 Posted July 5, 2004 Does anyone know if 5x130 Porsche wheels all have the same centre bore diameter, or do they differ? The design 90's I've bought have a larger bore than VW's 57.1mm, its about 70mm. I've seen some H&R adapters pictured with plastic spigot rings for the 'larger' bore. There's a second hand set of H&R adapters i'm interested in, but the seller says they didn't come with spigot rings, and didn't think they were needed :?: Quote Share this post Link to post Share on other sites
badlad1888 0 Posted July 5, 2004 I have just bought H&R adaptors and they came with the plastic rings. So i would guess that you should really use them to be on the safe side, you could probably buy them individually from an H&R supplier. Quote Share this post Link to post Share on other sites
PhatVR6 0 Posted July 6, 2004 My H&R's have a proper boss on them, never measured it, but I'm guessing it will be 70mm as porsche rims fit ferfectly on them. Quote Share this post Link to post Share on other sites
Andy T 0 Posted July 7, 2004 Just got tho the bottom of this now, H&R adapters have a boss size of Ø71.6mm (as per porsche design 90's) so the plastic spigot rings i've seen with the kits must be for a type of porsche wheel with a even larger bore. What type of rims are you running badlad? Quote Share this post Link to post Share on other sites
