SCC Double Centering System Wheel Spacers. We manufacture the spacers on modern CNC machines using high-quality aluminum. The wheel spacers provide a wider wheelbase, resulting in improved driving dynamics and design. Your vehicle leans less in corners and you can achieve higher cornering speeds. For system 2, the spacers are tightened with extended wheel bolts between the rim and the wheel hub.Wheel bolts are not included and must be ordered separately. The indication of wheel widening always refers to the widening for one spacer. Our spacers receive a general operating permit, allowing for quick and easy registration with the TÜV. With SCC spacers, you have the opportunity to achieve maximum results with minimal effort. Packaging unit: pair (= 2 pieces). Easy installation, they perfectly center the wheel thanks to precise internal and external machining that matches the vehicle's specifications. They are made of solid aluminum, machined following strict manufacturer data. Ideal for increasing offset (ET) when changing wheels or on original ones for a wider look and optimized road holding.
