I got some spacers from him before for an R6 caliper swap on my GSXR with stock 310mm rotors and completely forgot that I had to remove the dowel from the calipers to make them work. It wasn't a problem since the spacers were male/male. When Zoran sent me the new spacers for my 320mm rotors they were female/male because he didn't think I had pulled the dowels already. Mistake on my part for not telling him. I told him my problem and he offered to either make me a new set of male/male spacers or to source me a set of OEM caliper dowels. I told him I would rather have a set of correct spacers, but that the originals he sent me were already on the bike because I needed them at the time. No problem he said and told me I could return the old set after he sent me the new ones. The new set arrived and they're perfect. Thanks again to Zoran and crew at TWF!
