Hubcentric rings?

[uansari]

I have a set of 18X7.5 Volk GT-N's, and I wanted to know if I need a set of hubcentric rings...

I'm not sure what information I need to buy the rings... do I need to know the size of the Celica's hubs? If so, does anyone here know?

Any and all help is appreciated...

Thanks,

Usman

You almost certainly need rings.

I think all you need to know is the diameter of the centerbore of the wheel , and the smaller diameter of the matching protrusion on the hub (54mm in the Celica's case?)

Yeah, I've been doing some reading and that's all I need to know...

So does anyone out there have a set of 18" Volks that can tell me the centerbore? Also, does anyone know the Celica's hub bore size?

Thanks...

Ok, I called MVP Motorsports last night, who called Mackin for me...

Turns out I need rings with an inside diameter of 55mm and outside diameter of 65mm... just posting this in case anyone else needs the info.
