How Much Unsprung Weight Does An RB Performance 2-Piece Rotor Save?

Let the images do the talking. These rotors are all from a 04-08 TSX. First, an OEM Rotor. This rotor comes in at 17.8 lbs:

17.8 lbs for a stock TSX front rotor, with minimal wear. Rotor is not near the service limit.

Now, a Racingbrake 1-piece UP rotor for the same application. There is some added weight added coming in at 18.3 lbs with this rotor since it is a bit thicker than the standard rotor, and has more material in the hub area which is greatly reinforced versus the stock rotor :

Racingbrake UP 1-Piece Front Rotor, 18.3 lbs.

The 2-Piece rotor from Racingbrake, featuring a forged and CNCed aluminum hat, free-floating, center-mount design, and G3500 racing alloy material, weights in at a paltry 12.7 lbs per side! This is a 5.1 lb savings per corner versus the stock rotor, and 10.2 lbs of the whole front axle!:

Racingbrake 2-Piece Rotor for TSX Weighs 12.7 lbs!

With the ability to stand up to street- and track- duty pads, light weight for better acceleration and suspension action, and reasonably priced replacement rings, the Racingbrake 2-Piece Rotor is a definite winner for street performance and track-day enthusiasts. And if you are for show, you simply cannot beat the look for the cost.

Is it any wonder we chose these rotors for our HT-Spec Stage 3 Performance Brake Packages and for our HT-Spec TSX Project Build?

When the two piece rotor was installed the first thing I noticed was the improved acceleration, but after we got the pads bedded in properly we were braking so hard I think my tooth filling popped out!
