i saw them on thier site and was wondering if they look large enough to fit over the FC hub bore. anyone used or have any idea?

i dont see them being any better / worse than the ebay spacers
go for it if u feel like paying for some "JDM" tax

 

I have those on my FC(20mm front 25mm rear) for my FD rims, and they work great. Even at 100mph+ they dont cause bad vibrations. The only downside(if it really bothers your) is that the studs on the spacers are not the same thread pitch as the factory studs on the FC.

 

JDM tax? surely they have a supplier in the usa.

 

I love how the last picture is showing them installed on some rusty *** car
