I've looked all over the internet: The problem is the wheel size 14 inch x 4.5J - 4x100 - 39ET or 5.0J is very unusual for alloys and, if you draw it out (I'm an engineer, I can't help but think like this), doesn't leave much room for the thicker spokes on alloys anyway. Traditional Minilite wheels are much lower offset in the narrower sizes. I checked the sizes online for Minilite, Minator, JBW, Compomotive and Image and the offsets are all considerably less than the required ET39. Japan Racing make the JR19 but again ET values are very low. This is the only Minilite style wheel that I think might fit - Watanabe. They make the 14-05 F8F (aluminium and magnesium versions). Standard Alu ET is 45 with lower values available to special order, the Mag version comes in ET40 which I guess is close enough. Assuming you want silver alloys you'll need to specify that as well which brings the total to £276 (Al) and £303 (Mag). Those figures are based on the manufactures website, I don't know what they'd cost after you pay for shipping or order through a UK distributor. Volk Racing make the CE28N if you like a modern look. Personally I think Caterhams suite more traditional looking wheels but it fits. Unfortunately they are also even more expensive than the Watanabes.
