Agree 100%. Almost all aftermarket parts for cars get copied/improved/redesigned at some stage... Fair enough, Win Factory had the original design but there was never any mention or credit taken for their design in the f/s ad. The design has been improved and shipping costs to residents of Australia substantially less. I (and many others I'm sure) didnt know they were available until the f/s ad and considering the relatively low up-front cost combined with low shipping fee's, they've had a massive response... Kudos to Ezzupturbo for making these improved kits available to the members of aus300zx and also to Winfactory for the original design.
