Hi everyone,
new here, new owner of an used 2012 Honda accord tourer 2.4 type S wich I believe is the equivalent to your tsx wagon in the us.
I am planing of installing aftermarket wind visors on my front windows but I am unsure about the assembly due to those little parts I believe guide the windows.
Do I have to remove those to install visors? What are those exactly for? I noticed over here in Europe not all modells have them.
any experience anyone mixing them with visors+?

Thanks in advance
