Hello, I've just bought a set of rota grid drifts for my blob eye sti. Now the spiggot rings that came with the alloys fit fine but as I've got to run 5mm spacers on the front to clear the brembos there is play in the front wheels. I've been told the reason is as it tightens up its pulling the spigot ring towards the wheel and the spacer is not allowing the ring to sit inside the hub properly which is causing the play. Has anyone ever had this problem before? Cheers Josh.
