The point of this thread is to create a list of the weights of different stock parts and aftermarket parts for everyone's reference. People can post up what they are doing to reduce weight and ANY information about the weight changes achieved. The aim is to create an extensive list. I'll keep track of this thread as much as possible to keep the list up to date.
