VTT A9X Supra/BMW Z4 / G2X / G42 Billet Diff Lock Down Kit VTT noticed a hole in the VTT A9X Supra/BMW Z4 / G2X / G42 Billet Diff Lock Down Kit market for a high-quality, lightweight, NVH-friendly, and easy-to-install Diff Lock Down kit to improve diff stability under launching, and hard cornering. So we did something about it and went to work on a very innovative design that 100% positively locks the diff down from movement, while shielding it from adding a ton of NVH, and can be used with the stock diff, and subframe bushings.
