The reason I ask is my arms have a spoiler on them so are they aero? Never had an issue with clearance

Having spoilers on the arms does not make them aero.

This is a set of mk4 golf Aero arms fitted to my octavia

and from the inside:

yes sorry i have the aero blades too i was wondering about the arms themselves. I may just grab a set and see what if i like them.

My sister has them on her golf....wonder if i could swap them over without her noticing
