The gold calipers look great on MG and would look great on BSM. Not sure they would work so well on AW or LBB

I was surprised as well about the calipers until I remembered that the CCB calipers are 6 piston front and 4 piston rear, so it's not just that gold paint is heavier
I think that you're getting 8 lbs or so of savings per corner in
rotating mass, but the
unsprung savings is roughly 3 lbs in each front corner and 6 in the rear. Not that it matters a whole lot as both are somewhat small savings. For kicks, I did some calculations based on the weights shared:
Unsprung Savings (kg) Rotating Savings (kg)
Front Corner 1.31 3.96
Front Total 2.62 7.92
Rear Corner 2.82 3.53
Rear Total 5.64 7.06
Total 8.26 14.98
