ALTA Tensioner Stop for R53 Mini Cooper

At some point in your cars life, the serpentine belt that allows the crank pulley to drive the Supercharger and A/C pump will fail. When this occurs the OEM belt tensioner mechanism will plunge into the crank pulley. When this happens, the 3 parts that get destroyed can cost $300 in parts and not to mention the labor to replace them. This is where a tensioner stop comes into play. It is a fail-safe for a fail-safe!
