The Perfect Belt for Your New Supercharger Pulley
If you are changing to one of our reduction supercharger pulleys you may need to switch belts while you are at it. Although you can use the stock belt with a 15% pulley we still recommend you change to this slightly smaller length belt, and with a 17% pulley you really need to switch. Since your R53 probably has a few miles on it already why not take this opportunity to install one that will last you another at least another 100,00 miles. With advanced technology that matches the OE size, construction and materials Century Series Micro-V ensures optimal vehicle performance. Micro-V belts provide peak operating performance while delivering the highest value available.
