Tech Thursday: C6 Z06 Weights

c6z06

If you’re curious about how much parts weigh in your Z06, wonder no more… The data below was compiled by Corvette Forum members and organized by blaine123. It is invaluable as reference for the Z06 and people who race their cars as some of the parts are useful on non-Z06 cars also (there is a ton of wheel data…).

****To keep the list manageable parts included must have been upgraded to something better or lighter than stock****

****Conflicting weights were not changed until a 2nd verification from another member or a picture posted/PM’ed of the part weighed w/legit scale was received****

*Some parts are lighter, but keep in mind some parts are heavier due to better quality or more OEM functions retained
