Wheel Spacers and Shims Wheel track widening not only improves the aesthetic appearance of the car but primarily enhances stability and road holding, becoming an integral part of the technical solutions that Simoni Racing offers to make the car's setup sporty, precise, and safe. Simoni Racing spacers are only made with high-quality materials (Ergal 7075-O or Ergal 7075-T6) and undergo an anti-oxidation treatment. By using aluminum spacers and specific fasteners, you can give your car the appearance and qualities of a real racing vehicle. What are spacers? Spacers are shims that are mounted between the hub and the wheel, causing the wheels to protrude more towards the outside. This modification gives the car a sportier look, as well as increases cornering grip and general stability. Spacers can be found in various sizes: from 5mm to 30mm (which are mainly mounted on off-road vehicles and pickups). How to Choose the Right Size Place the car on a flat surface. Measure the available space between the fender and the tire shoulder on all four wheels. Keep a few millimeters of gap between the fender and tire shoulder. Verify the type of wheel drilling. Check the wheel hub diameter. Check the depth of the hub's mounting surface and the original bolts whether they have a conical or spherical head. Wow Effect The final effect varies depending on the size you choose. Objective: Spacers aim to widen the vehicle's track. But they also function to eliminate contact between brake calipers, wheels, and suspensions or arms. What material are they made of? In most cases, these discs are made of aluminum, in this specific case: Ergal 7075-O or Ergal 7075-T6 and are subjected to anti-oxidation treatment. Application List Spacers are NOT universal; thus, they have a long application list. Paying utmost attention at the time of purchase is therefore key to proper installation. How do I know if they are not the right size? Mistakes can be made during purchase. How we notice: - The spacer does not fit into the wheel hub - the spacer does not go into place, thus risking the tearing of the central collar. If the assembly is not done correctly, it is strictly forbidden to drive on the road. But doesn’t it damage the car? Contrary to what is often said, car spacers do not alter the suspension geometry in any way, do not compromise the balancing of the wheels, and do not change the turning radius. Purchasing the right car spacers for your vehicle is crucial to make this modification with complete peace of mind. How to Install a Spacer Park the car on a flat surface, place the jack under one of the four points, and lift the car. Remove the wheel. Clean the wheel hub with sandpaper and cleaners such as brake cleaner or degreaser. Install the spacer, positioning it on the hub, with the holes aligned with the hub's holes. Position the wheel on the spacer and secure with the bolts provided in the kit. Repeat the steps above for the other three wheels.
