Front Brake rotor differences and weight

Ive been looking online rockauto and amazon checking the difference in front rotor weight.

The two quality rotors Ive been looking at are Centrics 12565053 or Motorcraft BRR20. They also have a BRR4.

The Centrics are suppose to be the 125 high carbon Centric rotors. I think that is the correct Motocraft rotor for our truck but a few are listed anyone know?

The weight difference is making me lean towards the motocraft rotor. The Centric is listed as 22 lbs and the Motocraft is listed at 34 lbs... thats a huge difference! THe BRR4 is listed at only 23 lbs. whats the difference between the two motocraft rotors?

Anyone know how accurate this is?

never thought of looking at brakes this way. why would you go with the heavier rotors?

i am running powerslot rotors and hawk pads. great combo for towing.

Heavier rotors have higher carbon content and always a better rotor.

I don't think so, something I would like to know. I've heard plenty of conflicting things. Everything I've read says that drilled and slotted rotors are not as goo as solid on our trucks. I've always used a good quality rotor though. So trying tiger a feel for it.

my thinking is more weight takes more energy to get moving and longer to stop.

i have slotted rotors on my front and they are great ever towing 16K, never used drilled

they say drilled are not good for towing, too much heat and not enough material and then they wrap, so for trucks stay with sloted only!!!

i would think heavier rotors would resist warping more as it is more metal to dissipate..... well... no only if they are actually bigger in some dimension....HMMMM...

The Motocraft weight difference is BRR20 is 2WD with hub and the BRR4 is 4WD rotor only.
