Stock mounts are made from soft rubber and are sometimes filled with fluid to give a car the most comfortable ride possible. The soft rubber and fluid helps to reduce the total amount of vibration, noise, and harshness (NVH) that is transferred into the cabin. The problem with this is driveline slop. The stock mounts allow a lot of excess movement and increases the amount of time it takes to transfer power to the wheels.

In order to address this issue, performance mounts can be substituted to reduce the amount of slop and transfer power to the wheel quicker. Two options for this are polyurethane mounts and solid mounts.

Solid mounts are great for an immediate transfer of power but allow for a ton of noise and vibration to be felt and heard in the cabin of the vehicle. This is great for the track where there aren't any issues with excess harshness, but as a daily driver, this can become an annoying pain in the neck.

The best middle ground is Polyurethane. Polyurethane is much stiffer than rubber and gives you the much stiffer feel you may be looking for. This allows for the increase in responsiveness, but isn't so extreme that it transfers all of the sound and vibrations into the cabin. This makes it much more comfortable for daily use while still reinforcing your driveline.

This can cause internal damage to your diff, leaving you stranded at the track or on the side of the road.

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 its time to the launch the transfer case cannot move as it could without the insert. These come as a set of two with 2 bolts to keep them in place. Install time once you get to them is about 2-3 minutes. Could not be easier. Put some lube on them, push them in, and tighten the screws. These are a MUST for high-power G8X, and F9X X3/X4M Builds. All platforms they fit are below. Features: 6061- T6 aluminum construction Easy to install Fully reversible Do not add NVH

Instead of completely replacing the mount, simply make a billet aluminum insert for them. This leaves the feel of the factory mount in place but stiffens them up quite a bit removing unwanted engine movement without rattling your teeth out or emptying your wallet.

VTT 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 differential 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. 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.

For the track, solid mounts are great. Solid mounts give you an immediate transfer of power, at the cost of increase NVH. This is great for the track where comfort is the least of your worries and power is all that is important.

These aluminum mounts are a direct replacement for the stock rubber bushings and have been lightened to remove excess weight. Using aluminum instead of rubber eliminates the "wind up" inherent in rubber mounts, and this deflection slows suspension & drivetrain response. The tradeoff is an increase in NVH.
