I am using the standard Haynes Roadster rear uprights. The Wilwood calipers I want to use require a disc to be at least 260 mm in diameter. I thought that I would use the 273 mm discs with four holes from an RS Cosworth.

Their was no RS Cosworths imported here in the US so the 273 mm discs are unavailable. I have not been able to find any US Fords using that size or larger either.

Does anyone know of a disc from an American model that is 273 mm or even larger that I can use? I can order 273 mm discs from the UK, but the postage is far more than the discs themselves. Right now I plan to use 16" wheels.

Thanks,

Bill Box
