does anyone know if et20 will fit my focus, the guy whos selling them said they were fitted to a focus before he put them on a 406 coupe.
im not sure how the et thingy works and i know my alloys are et35, so will they stick out of the arches or would i need spacers, thanks for any advice fellas

 

The lower the offset, the further out in the arch the wheels will sit. You shouldn't really go any lower than ET42 on a focus as it will affect handling and knacker wheel bearings a lot quicker. ET20 will scrub the arches if it's lowered!

 

stick way out for focus as richie has said ,so unless you have rallye arches I would look elsewhere,
