Heard from Max, he'll be making some more for the 408cc version, 8 sets he says, and also 2 sets for the 398cc version. Cost will be £50 a set, that price may be if he sells them on Ebay direct to you, if he sells them through me then I suppose I'd have to add on P&P as well or I could possibly ask him to post direct to you. Lets wait and see what he does.
