The JWT flywheel weighs in at 15.4 lbs by using an aluminum flywheel with a steel ring gear and friction insert. This is about half the weight of the dual mass stock flywheel and will help improve response. The friction insert can also be replaced if it ever wears out.

These dual bolt pattern flywheels will work with the stock 350Z Clutch (850KG) and the 300ZX Twin Turbo Clutch (1150KG), for larger HP applications.
