Wilwoods and Ultraleggeras?

Hi,

Just wondering if anyone has run or is running a similar set up. Ive got a 182 cup, and wanted to fit a set of 15"oz racing ultraleggeras but i want to know if a set of wildwood 4 pots would fit under them. also are the ultraleggeras a straight fit or do they require spigot rings?

Thanks in advance.

I've got the jamsport 295mm kit under 2118s if that helps mate. They are the 37et and are fine. I also ran them with the standard trophy turinis which are either et42 or 45 without any clearance issues.
