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.
