Thought this might be useful for some people as I get asked about them a lot via PM and e-mail.

That's a pretty handy guide.

Nice one X-Factor

 

 

Up for those who might find it useful

 

What is the spacer exactly? Wheel spacer? or something else?

 

Spacer that goes between the hub face and the caliper

 

Gotcha

 

thank's for the info mate

 

Might seem like a daft question, but how about using Focus RS Mk1 Hubs/brakes on an odinary MK Focus?
