Well I guess we will have to answer that question a little early with the info for Day 3. The stock sub with Drum brakes and these roller wheels and tires weighs 372lbs.
Since the brake are not here yet, Once we put front brakes on the car, what will it bring the weight in the front back up to?
Which is lighter stock drum brakes or Big 13 brakes from Wilwood?
So you are Correct the Chassisworks subframe contributed to 31 lbs loss, but how much weight will we put back on when the 13" Wilwood 6 piston brakes arrive?
I was shocked by this number also.
