So apparently this wrc spoiler i can use for the roads so how can i put this. "apparently there is a tuv certificate so i can register it to my car if it makes sense.) Then again. I came across some videos and i saw some spoilers being flush or just glued on?
Now my question is. Are these 2 spoilers diffrent from each other? If so. Would it be better for me to go with TIPE A one or TIPE B one? Unless i suck at doing research and they are the same thing. Thanks in advance.

I would say that A is better. If you look at images of the wrc octavia you can see the line that goes thru the emblem on the trunk because the uper and lower parts are one, you can see the same line on A, while the ebay one could just be the wing part witch would make it less durable and also less acurate to the wrc octavia
