New from T.O.P. come optional shock springs for the Photon, Sabre FD and Sabre FD Mini chassis. Testing showed that the current breed of spec tyres call for a softer spring setup in order to receiver a wider suspension tuning window. The new 274gf/mm, 260gf/mm and 248gf/mm springs rates allow for more play with the shock stiffness and can give the driver an advantage depending on the tyres used. The springs come in pairs and are marked for easy identification.
