FK hubcentric spacers need milling?

[adamlewis01]

Iv heard that people say that FK spacers need milling to fit but which bit needs milling as its probably not that big of a job if its the locater ring.

Its these spacers im intrested in:

System (A Centric) - Supplied with a hub locating ring.

what size?

 

[adamlewis01]

26 so 13mm either side. why?

 

[Fred@BTM]

that's what i have, i just took a grinder to the hub flange or the rear drums, only had to dress off 1mm if that, easier than machining the spacers

 

[adamlewis01]

so if i were to mill the spacers which bit would i need to mill?

 

[Fred@BTM]

you don't, grinder to the hub flange = MUCH easier
