Our 3.25†carbon driveshaft is now available now for the 300ZX 2-seat Twin Turbo 5-Speed Coupe. The shaft only weighs 15 lbs and comes with special grade 12.9 uber strength hardware with back up lock nuts to ensure no loose bolts. We have been using this billet aluminum style plate for over 10 years on thousands of 1000+Hp Supras, BMWs and many more without any bolt issues.
