An extremely useful compilation of weights for those that are serious about performance

 

Like most things, different people will have different claims for some of the weights....that is the way it is :)

 

Thanks to everyone who contributed to this list!!!

 

=======================
PLEASE BE CAREFUL WHEN PURCHASING AFTER MARKET EQUIPMENT. SOME PARTS MAY BE HEAVIER THEN OEM EQUIPMENT.

For example, I bought some aftermarket OEM rotors that were 1lb heavier then my stock rotors. IF you are concerned about weight, ask the weight before you buy.
