I could not get a value for the dust shields, they were too light...similar to an empty soda can...we're talking ounces. Caliper weights do include pads, as you mentioned.

Also, did you by any chance get seperate measurements on the disc vs. caliper assemblies?
lucid: Thanks for waiting...I've been real busy with work.

My trunk weights did not include the lights/carpeting, trunk release or hardware. They were already transfered to the VRS lid. My measurements are as approximate as the tolerances in the $50 digital bathroom scale. (...sorry swamp.)

VRS double-sided cf bootlid w/o hardware, carpeting, etc.---- 14.9 lbs.
OEM trunklid w/o hardware, carpeting, etc.------------------ 26.0 lbs.

Brembo 380 x 34 front rotor -------------------------------- 24.8 lbs.
OEM front rotor-------------------------------------------- 26.6 lbs.

Brembo 380 x 28 rear rotor --------------------------------- 17.0 lbs.
OEM rear rotor -------------------------------------------- 22.8 lbs.

Brembo 6 pot front caliper -------------------------------- 13.0 lbs.
OEM front caliper ------------------------------------------ 15.2 lbs.

Brembo 4 pot rear caliper ---------------------------------- 9.6 lbs.
OEM rear caliper ------------------------------------------ 12.1 lbs.
