Britons slim the rims
In sports cars, the key factor is performance, so designers are trying to lower it in all available ways so that the car can drive even faster. The British company BAC, together with Dymag, decided to take a few extra pounds off the rim, an inherent component of each car.
The enemy of racing cars is mass, because every kilogram you need to put on the move and stop, and the more they have, the more power they need. When constructing high-performance cars, unnecessary components are thrown away and lightweight composites are used to lower the weight.
Quite a few pounds in the rims, so Ford announced recently that his Shelby GT350R model will be equipped with carbon fiber wheels. The American giant is not the only company that goes in that direction and the same idea came from the British company BAC. The problem is that the carbon fiber rims are extremely expensive, so the British have developed hybrid wheels that are slightly cheaper, and at the same time 20% lighter than standard aluminum alloy wheels.
BAC wheels are therefore not made entirely of carbon but of aluminum, and of carbon fiber formed rims. Thanks to that, the 17 “wheels in size 7.5 x 17″ for the front axle weigh only 5.7 kg each, which is 23% less than traditional wheels. In the case of the rim, on the rear axle size 9 x 17 “, the weight savings are slightly larger and amount to 6 kg per piece. For even greater weight reduction, titanium screws were used, each weighing 30.2 grams, allowing each wheel to save another 212.5 grams.
