We have chosen to select the best materials to meet the specificities and constraints of each practice (dirt, asphalt or daily use). This range benefits from all the technology and know-how acquired by Bos Suspension for more than 20 years in 2 and 4 wheel sports. ![]() Rebound and Compression adjustments Our Toyota Yaris GR-4 shock absorbers (Earth and Asphalt range) have many adjustment possibilities. Two-way compression settings: Low speed and High speed. -Rebound adjustment. -Spring Preload (Body Height) Find the perfect setting for your preference and the terrain you're riding on. Drive faster, harder, safer, with maximum fun and precision with our range of Toyota Yaris GR-4 specific suspensions. ![]() CAS System Selective Damping Control. Put all the power to the ground. This technology, available on the Earth and Asphalt range, corrects the shock absorber hydraulics according to the load applied to the wheels, allowing faster grip recovery and better traction. This technology is the result of a long work on the dosage of the loads applied to the shock absorber. ![]() Light spring Every component of our range is important! That's why we use high quality, lightweight steel springs with a very high working capacity. These springs are subjected to an advanced manufacturing process to withstand even higher stresses. These springs have up to 40% less mass than standard springs, which allows a significant weight saving without affecting the strength and rigidity of the spring. ![]() Hydraulic compression stop Adjustable Hydraulic Compression Stop on the Earth Kit and Adjustable Hydraulic Compression Stop with needle for the Asphalt Kit. These bumpers are specially designed and developed by our design office in Toulouse. Each hydraulic compression stop plays an essential role in the operation of your shock absorbers and allows precise control of the last few centimeters of travel. Thus, you keep in any situation an optimal operation of your suspensions and you can devote yourself to 100% on the essential: the piloting! ![]() Track/Circuit Kit The Road Kit offers a mastered management of the hydraulics of your shock absorbers. This management has been developed and adapted specifically for the Toyota Yaris GR-4 to offer you a comfortable and safe dynamic sporty driving experience. The height of the body and the damping gain are adjustable, it allows to adapt easily the Toyota Yaris GR-4 to all types of driving "Circuit" or "Track Day". ![]() Rebound stop This rebound stop on the Earth and Asphalt Kits allows you to use the full potential of your shocks. It allows precise control of the last few centimeters of rebound travel of your shock. Keep your suspensions running smoothly in any situation and concentrate on your driving. ![]() AMX-1 oil Each product has its own specificities. That's why we recommend the use of AMX-1 oil, designed to keep your shock absorber running smoothly and avoid premature wear. This oil will also reduce friction and parasitic noises, while guaranteeing a homogeneous feeling and a good operation, even when the temperature rises. This specific oil has been tested all over the world on all the major competitions. It is the result of the experience accumulated by Bos Suspension for over 20 years. ![]() Quick and easy maintenance Need to do the maintenance of your shock absorbers, nothing more simple!
