The bushing in the stock firewall mount is very soft and compliant rubber that easily tears. The damage gets progressively worse as the bushing deteriorates with age and underhood heat (especially on turbo models). The excess engine movement from a torn firewall mount will cause slop that translates to unresponsive off-the-line acceleration, poor shifting performance, odd clunks and accelerated wear on other mounts.

Here is a failed (torn) stock upper firewall mount from an unmodified stock vehicle. This damage will go undetected for a long time because the upper torque arm covers the upper firewall mount bushing, making it impossible to inspect without removing the upper torque arm. By then it's too late and the damage is already done. If the mount is not replaced, it is common for the bushing to completely separate from the mount itself!

If your car has more than 50k miles or is more than 5 years old, you should consider replacing the stock mount. Even if your car is not modified, the mount will wear - especially on turbo models and modified vehicles that put additional stress on the mount.

The QBM Performance Upper Firewall Mount is a brand new mount, reinforced with 97 Shore A Durometer polyurethane. It will outlast and outperform the stock mount due to its reinforced design, and is a must on turbo models and modified vehicles.

The QBM Performance Upper Firewall Mount is easy to install using basic hand tools, and installation takes about 45 minutes.
