All products that are designed to stiffen or reduce drivetrain movement inherently have the tendency to increase NVH or Noise, Harness, or vibration. While these bushings inserts have been found to add little NVH in most instances. Your results and sensitivity to NVH may vary. This product is designed to reduce drivetrain movement, and that was the goal when designing and manufacturing this product. Returns for NVH are not accepted once products are installed.
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. This design uses existing mounting points on the vehicle, you do NOT have to remove the subframe or the Diff to install. Simply remove 4 diff bolts, drill two holes in the subframe slightly bigger, install two M10 riv-nuts, and install the lockdown, you do not even have to move the exhaust. A typical install can be 15-30 minutes for someone who is experienced working on vehicles, an hour if you like taking it slow. You WILL need a Riv-nut tool to install the Riv-nuts, we provide a link below for what we recommend on Amazon.

VTT Billet BMW Transfer Case Bushing Inserts
Soft bushings are the enemy of launching hard, and keeping your drivetrain together. The BMW Transfer Case bushings are notoriously soft, and that is the opposite of what you want when launching a car hard. You can replace the bushing with a solid one, but this is time-consuming usually requires lowering or removing the transfer case, and results in a lot of added NVH. The best path is simply to reduce the amount of flex of the factory bushing so you keep the nice manners when cruising around town, and at idle, but when it's time to launch the transfer case cannot move as it could without the insert.
Uses FOUR connection points on the Diff, and two on the subframe for the ultimate in positive diff location, this will stop all diff movement on launch, saving your guibos, etc
