Lightest Weight BBK

Ok - so maybe you are getting "negative" comments because you made a poll out of something thats fact. Its like making a poll to see whats heavier - 10lbs or 20lbs or 30lbs - if your question was - which one is better and why - then thats a different story.

Honestly - shaving weight off your brakes isnt gonna do all that much unless you track your car like travisJB does - and even if you do - you probably want a nice hefty rotor which can handle a lot of abuse from a track pad in high heat - and historically - the lighter your rotor the thinner it is and the thinner it is - the more crappy it is on a track etc etc.

A lot of people seem to be weighing the caliper / pad / rotor combo and they see that they saved 2 lbs over stock and they rejoice that they are saving unsprung weight - this is not true - only your rotor turns in that assembly.

Not bashing your thread but just saying - if you gonna make it be about opinions then polls make sense - but when you can measure these rotors and see which ones weigh the most - makes no sense to make a poll

It's all unsprung weight, the entire mass that moves with the wheel assembly is counted. Rotating mass is just the wheel, the hub and rotor. Reducing rotating mass helps accelation, reducing unsprung weight helps the suspension responsiveness.

But as you pointed out you can't really make a poll out of this. Asking for factual information would be far more useful.

Ahh unsprung weight not rotating mass - oops
