Porsche Interview 2013 Wheel Dynamics
Porsche Rims Fortunately for the Porsche enthusiast several manufacturers made light weight rims designed exclusively for Porsche boxsters while providing sleek styles with numerous finish options. Trendy wheel finishes include chrome, polished aluminum, painted aluminum alloy and more. This also includes hyper-silver, silver, white, black, gray and Anthracite. While many of us choose aftermarket wheels for the good looks ,there are many important privilages resulting from reducing a rims weight when compared to factory steel rims.
The additional strength of Porsche aftermarket rims can notably reduce tire deflection and tire rollover while cornering. This also increases brake cooling with Porsche aftermarket wheels because alloy is a great conductor of heat. The large mass of aluminum rims help dissipate heat from the brakes.The open design of 5 spoke and 6 spoke custom wheels allow more air flow over the brakes cooling them as you drive.
One of the most significant factors affecting your Porsche is the reduced weight of custom wheels over factory steel wheels. By reducing weight, custom rims provide improved acceleration and braking. You must also be careful not to exceed the design weight of the original wheels and have the reverse effect by adding larger rims and tires or aluminum alloy rims that are gravity cast. Gravity cast aluminum alloy custom rims are cheaper but heavier and prone to bending. Look for aluminum rims that are either low pressure cast or forged, they cost more but will reduced weight and adds strength.
Keep in mind that sizing up or adding larger Porsche rims and tires will actually add weight. So plus sizing should be done the proper way. By using a larger diameter rim with a lower profile tire it's possible to properly maintain the overall original diameter of your rim and tire. It's important to keep your new custom wheels within 3 percent of the original equipment. Differences larger than 3 percent can cause problems with transmission shift points which can decrease fuel mileage. It can also confuse braking system computers, reduce ride comfort and cornering capability. Go for wider rather than taller wheel - tire diameters, the results is a larger contact patch and a sportier look.
One concern over the years has been to have Porsche aftermarket wheels CBD or CB (Center Boar Diameter) which is a direct fit for the Porsche.
Another concern is that Porsche aftermarket manufacturers must take into consideration the proper off-sets and size options. Porsche enthusiast can purchase a better design wheel for the same price as other manufactures offer yet specific to the Porsche owner's standards.
