Cutting the decklid? (Porsche fan)

[kdanie]

If you use the Fat Performance 911 shroud cutting is required. The Fat shroud was developed for offroad competition so clearance was not an issue. No case machining is required either. It is the least expensive of the 911 shrouds. If you use one of the other shrouds cutting is not required because they were designed for the type 1 from the start and case machining is required.
