Hi,

Surely this has been covered before, but i do have a question not regarding the conversion itself, but one other thing.

I intend to do the conversion, using Brembo FRS calipers, and ST170 hubs, but want them to run in my Speedline 2110 16x7 wheels without a problem.
I know that in Compomotives, it would run fine, but i haven't checked the clearance in mine and do not want to run FRS discs, want some 2 piece discs with max 310mm diameter.
What i need to know if anyone did this before, is the measures of the bell regarding the overall height and offset?

I know that Gaz_88 and a lot of others made a brake conversion on a Focus, but some of them run spacers and/or long studs, and i do not wish to do this...

Any help?
