How much is the weight difference exactly? Do you have the part number for that roof bow? Thanks in advance.
Part number is 41007168999. Cost about $35. The roof is not a stressed member on this car, so this is more about stopping the cf roof getting too indented if pressed. You need to add some padding between roof and bow.

Sunroof to cf roof is a net 61 pound saving. Airbags were another 10lbs or so ( only if running race seats/cage/harness).
