For a 4*2, I would even go to a ratio of 8.5.
You will need to take of the fan of the speedo because the body is not high enough.
Two options, put the fan in front of the speedo so that cool air goes over the speedo or just take the fan off completely; but if the speedo is thermaling (too hot!) you will have to put it on again.
But in my opinion, a 5.5 for a B4 is too much, I would rather go for a 8.5.
If you have some more questions, let me know.
