350Z DE RPS Billet Segmented Aluminum Flywheels

The faster moving outside gets hotter than the inside. Because metal expands more the hotter it gets, the outside of the heat shield expands more than the inside. Traditional heat shields are made of one piece metal rings, so when the outside expands more than the inside, the only thing the shield can do is warp. The segmented heat shields are not connected so they can expand and contract without warping. A warped heat shield causes the clutch to slip, which causes more heat and more warpage.

Our Billet Flywheels are dynamically balanced after CNC machining. Other flywheel manufactures assume that since they CNC their flywheels it comes off the machine fully balanced. This would be true assuming the density of the aluminum is constant throughout the part. Unfortunately even the best billet material is not evenly dense throughout and the starter ring gears are never perfect.

RPS Flywheels are also fully rebuildable for the life of the car. Weighing in at 18lbs. Fits the 03-06 350Z.
