Yup. My OEM's were 30 lbs each almost exactly. What's odd, though, is that when I weighed my RB front rotors they were just over 21 lbs each brand new and yours show 22.5 lbs each....

FYI guys. This is the last day to sign up for the GB at the deepest discount. FYI... RB doesn't require any type of deposit right now, so if you are thinking of getting these you should sign up now.

 

That's an older scale but it was usually accurate to within .5 lbs. Both showed the same weight multiple times.

 

You guys mean OEM BBK Rotors or Sedan Rotor weight? Sorry if I missed.

 

OEM Akebono brakes. These are not a direct replacement for non sport brake rotors, you'd have to upgrade calipers and brake lines too.

 

Wow, this is a really good item. This with a light weight forged rim can save you double digit lbs per wheel!

 

Already posted this over on Driver, but figured I'd post here as well. Incidentally, I believe you can still get a GB discount on these (allbeit not as large as before) if you order before the end of the week.

Update on the RacingBrake 2-Pc rear rotors!

Just went in for the test fit last week and everything looks good.. they only need to make a slight modification to the seating surface for the internal parking brake, otherwise fitment looks perfect, so production should start soon.

FYI... they used 6061 billet aluminum for the "hat" part of the rotor assembly to help save additional weight. This helped these rotors come in at 4lbs lighter than the factory rotors per side. While not as great of a weight savings as the fronts, that's still a huge weight savings, especially considering that's both unsprung weight and rotating mass. Here are a couple of pics of the rotors on the scale:




They are hoping to have the first preproduction units ready to install on my car before the end of the month, so I will keep you guys updated.

 

hows it going???
