JBW Flat Boy Steels - Will VW Centre Caps Fit?

[Pwillt6]

Hi Guys,

Just got myself a set of JBW Flatboys steels in 20" (much like the Navis Schmoove) and wanted to get some OEM VW centre caps. Does anyone know of the OEM slotted black centre caps fit these wheels? I know it can depend on the bolts but does the centre of the wheel also dictate if they will fit as i heard some caps need trimming etc to fit the navis range.

Thanks!
