Superformance Halibrand style wheels

Brian Stewart
My current wheels will likely not fit under my MKII rear bodywork. Does anyone have a set of 8" and 10" GT40 MKII Halibrand style wheels from Superformance they could run a rule over so I can see if they would make a suitable alternative?

The measurements I am after are labelled A - N on the diagrams below.

Hello Brian,

I have a spare set of wheels for my Superformance MKI which are Halibrand style.

They should be 8" and 10"

I have to dig them out of the basement and can measure them tomorrow.

What I do not know is if Superformance has a differences betwen MKI and MKIIwheels?

Thanks Marcus. As I understand it, their Mk I wheels are BRM style, while their MKII wheels are Halibrand wineglass style.

The "Wineglass" type Halibrands supplied by Superformance are the same for either MK I or MK II application. On a SPF MK I you may choose either the "BRM" six-spokes or the Halibrands. I have a set of the 8 & 10" Halibrands available but not at hand to measure. The pin dimension and PCD are the same as the original cars and most of the currently available GT40 wheels.

Hello Brian,

here we go - in the .pdf you find the measurements.
Please check if everything makes sense to you.
If you need additional measurements / pictures let me know.
Some measurements are not exact and are marked with "ca."
