File this one under "Why hasn't anyone else thought of this?" Traditional flywheels are prone to warp because of their one-piece design. As it spins, the outside of a one-piece clutch disc moves faster and gets hotter than the inside. As we all know, hot stuff expands so the outside of a clutch disc will expand and warp the entire disc. Solution: the "segmented" heat shield system. RPS Performance Products has chopped the traditional disc into four quadrants so that each piece can expand and contract without warping. Duh. It's called a Cyn-R-G Segmented Flywheel and it's even lighter than a traditional flywheel. We think the Cyn-R-G sounds like a good idea, but have yet to hear from someone who's got one. Anybody?
