BFI Dogbone Insert Stage 1 (Version 1) - MK7 / 8V / 8S
Our Stage 1 Torque Arm Insert is aimed at maximizing daily comfort while still offering optimized performance gains over stock. These are the only MQB inserts available that feature a specifically engineered dimension that limits unwanted vibration, offering the best compromise available. We recommend the Stage 1 insert to majority of our customers.
Under hard acceleration, the pendulum mount (commonly referred to as the "dogbone" or by VW as the "torque arm") acts to limit rotational movement of the engine. The factory bushings do a satisfactory job, while limiting vibrations, but only during sedate driving conditions. When pushed hard, those bushings flex creating a vague feeling in the engine and gearbox and adding to the dreaded wheel hop phenomenon.
Our pendulum mount torque arm insert fills the voids in the stock rubber bushing, making what was a soft rubber bushing with voids into what behaves like a solid mount. With the insert installed, you will notice that throttle response will feel better and your shifts will feel more crisp and defined, especially on manual transmission cars.
