wheel spacers

[Talonmotorsport]

10mm spacers will just be a straight through job I would have thought so don't need to be off set and threaded. You can buy +10 +20mm longer wheel studs from rally design or burton if their going on a roadster. To be honest the longer studs won't be to stressed unless you have made your chassis from solid bar,clad it in lead sheet and you weight 60stone. A good machine shop could knock those up in about an hour (ish). Unless your talking about the rings that pack out the centre mouting ring?
