RPS Billet Flywheels are the pinnacle of RPS engineering with their new patented segmented flywheel. These flywheels utilize RPS's segmented heat shield system. Where traditional heat shields can warp because of the uneven heat produced by your clutch due to the one piece flywheel heat shield design. RPS Segmented heat shields are not connected, so they can expand and contract without warping. RPS flywheels are also dynamically balanced and zeroed after CNC maching. . Because the metal expands the hotter it gets, the outside of the heat shield expands more than the inside, causing an uneven surface and/or warpage, which can lead to more warpage. These flywheels are made from aircraft quality billet aluminum and are fully rebuildable for life. Anodized and laser engraved.
