Quick ViewLooking to fix the diff bolt issue on your F9X X3/4M? VTT has taken a 3 pronged approach by offering a triple solution, one part of the solution is the Rear diff bushing insert kit. This is pressed into the factory bushing and fills the voids in the bushing. This keeps the stock bushing ride compliance but removes any unwanted movement. These are sold as a kit and are available in rear side only, and front and rear sides both. Adding in the front side increases installation time, and difficulty as the diff will need to be dropped, and a tool will need to be used to press in the front side bushing Kit includes:
- One Billet Bushing insert
- Two 46mm Hardened Steel Washers
- One 12.9 M14 Bolt
- One M14 Lock nut
- Optional front side bushing which will fully lock down the bushing. (requires the diff to be lowered, and the bushing pressed into the front)

Soft bushings are the enemy of hard launches and drivetrain longevity. The factory BMW transfer case bushingsāespecially on the G8X and F9X platformsāare notoriously soft. Thatās the last thing you want when youāre putting serious power down.
Sure, you could replace the entire bushing with a solid one, but that often requires lowering or removing the transfer caseānot to mention the added NVH (noise, vibration, and harshness) that comes with it.
Our transfer case bushing inserts offer a smarter solution: reduce bushing flex without sacrificing comfort. You keep smooth, quiet drivability around town and at idleābut when itās time to launch, the transfer case stays planted.
Fitment Notice ā Two Versions Available:
BMW uses two different transfer case bushing types. We now offer Version A and Version B inserts to match.
ā ļø You must physically inspect your vehicleās bushing to determine which version you need.

Select options This product has multiple variants. The options may be chosen on the product page / DetailsVTT noticed a hole in the F9X X3/4M 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 M8 riv-nuts, and install the lockdown, you do not even have to move the exhaust. A typical install can be 30-45 minutes for someone who is experienced working on vehicles, an hour or two 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. Features:- Lightweight 1.5 lbs for the entire lockdown plate
- Uses FOUR connection points on the Diff, and three on the subframe for the ultimate in positive diff location, this will stop all diff movement on launch, saving your guibos, etc
- 100% Billet construction from 6061-T6 aluminum
- Anodized in 3 colors for corrosion resistance, a long-lasting finish, and good looks
- The subframe does NOT have to be removed for installation
- Uses all 12.9 grade hardware
- Does not add excessive NVH
- Positively locks down the diff to eliminate all unwanted movement under launches, acceleration, cornering, etc.

Serious traction starts here.
VTT is proud to introduce the Billet DUAL POINT G8X Diff Lockdown Kitāa must-have upgrade for high-performance G80 owners. The factory differential bushings are notoriously soft, allowing excessive diff movement that robs you of traction and stability.
As the G8X platform continues to push performance boundaries, the OEM components reveal their weaknesses. One major flaw? Significant differential deflection under hard launches, often resulting in broken rear bushingsāa growing issue in the community.
š” Our solution:
What BMW should have done from the startāa true DUAL-POINT Lockdown System that secures the differential at four key locations:-
Precision CNC-machined billet pucks at the lower differential mounts
-
Matching billet pucks at both secondary subframe points
This setup locks the diff down completely, eliminating unwanted movement and dramatically improving stability under launch and aggressive driving.
š ļø Easy Installation:
No subframe or diff removal required! Just drop the exhaust and heat shielding for access. A straightforward, no-hassle install.ā ļø PLEASE NOTE:
NVH Disclaimer:
All products designed to stiffen or reduce drivetrain movement inherently have the potential to increase NVHāNoise, Vibration, and Harshness. While these bushing inserts typically add minimal NVH, results may vary depending on your vehicle and personal sensitivity. This product was specifically engineered to minimize drivetrain movement. Returns due to NVH will not be accepted once the product has been installed.Exhaust Clearance Notice:
This product may require exhaust system modifications. Depending on your exhaust brand, fitment, and layout, adjustments may range from minor to significant.-
VTT is not responsible for any necessary exhaust modifications.
-
Vehicles using the stock G8X exhaust will almost certainly require modification.
Returns due to exhaust clearance issues will not be accepted once installed.

Quick ViewIntroducing VTT Solid Engine Mounts for BMW G8X VTT is proud to offer our Solid Engine Mounts, designed specifically for the BMW G8X M2/M3/M4 platforms!
Why Solid Engine Mounts?
Drivetrain movement is the enemy of high-performance vehicles. As power levels climb and 1/4-mile and lap times drop, the need for a fully solid engine mount solution became clear. These platforms are no exception, and weāve addressed the gap in the market with a robust and reliable solution. We took the factory engine mount design and engineered a solid mounting solution that fits seamlessly within the same space constraints. The result is the only solid engine mount available for these platforms.Key Benefits

Important Note on NVH
These mounts are intended for RACING purposes. Please be aware that these mounts will increase NVH (noise, vibration, and harshness). They are designed for enthusiasts seeking zero movement and are willing to sacrifice some comfort for ultimate performance. If you choose to install these in a street car, understand that the level of NVH increase will vary depending on other drivetrain components, such as transmission or transfer case mounts. Refunds will not be offered for NVH-related complaints. -
