Titanium K-frame Bolts
For everyone's entertainment:
OE steel bolt: 4.7oz x4 = 1lb 2.8oz
Titanium bolt: 2.5oz x4 = 10oz
With a weight savings of 8.8oz for a set that is nearly half the weight of the steel bolts. Further reduction can be performed if one shortens the bolts down to the bare necessity of full thread engagement.
For the average enthusiast saving a 1/2lb isn't much but when everything is under the microscope to maximize weight reduction it all adds up. My next challenge is to see how much weight I can take out of a BB K-frame.
