Hi, I just weighed the stock drum system and it came out to 24.8lbs for everything. We are at 14.2lbs for the Wilwood setup for everything and the baer kit is 10.1lbs without the iron rotor. So you can see this is dropping a lot of weight off of the trucks. We dropped 10.6lbs compared to stock and at least 5lbs compared to the Baer system. If you have anymore questions please let me know. Thank you. Oh yeah, Daron just let me know when you want to drop the truck off for the frame and stuff. I will even come get it for you. haha.
