Description

The Vargas Turbocharger Technologies VTT Ultimate G8X Lock down Bundle provides a robust solution to enhance traction and stability for high-performance G8X M3/M4 owners. It targets the inherent weakness of the factory differential bushings, which are prone to excessive deflection during hard launches, often resulting in broken rear bushings. This kit utilizes a DUAL-POINT Lockdown System, featuring precision CNC-machined billet pucks at the lower differential mounts and matching billet pucks at both secondary subframe points. This design completely locks down the differential, eliminating unwanted movement and significantly improving stability during launches and aggressive driving. The bundle includes options for the differential lockdown kit, and also offers optional transfer case bushings (Version A or B, requiring inspection of the vehicle's bushing type) and upgraded 12.9 grade bolts and hardened washers for increased strength and durability. Multiple color options are available for the billet components. While Vargas aims to minimize NVH, results may vary, and returns due to NVH will not be accepted once the product is installed. Additionally, this product may require exhaust system modifications, particularly for vehicles with the stock G8X exhaust. Vargas is not responsible for any necessary exhaust modifications, and returns due to exhaust clearance issues will not be accepted after installation. The product is backed by a 12-month warranty.
