So I have an H55 and was replacing the clutch master the other day. In doing so I realized I have a booster for the clutch master and was wondering why? Every H55 I have ever seen does not have the booster. It does have a vacuum line to it. Didn't know the advantages of having versus not having, and if I removed it how that would affect shifting. Are the H55 internals going to be different as well? Kinda a weird question, just curious.
