SUSPENSION 17 7. SUSPENSION SYSTEM LAYOUT A. FRONT SUSPENSION  Front Suspension is McPherson type, independent suspension with the shock absorber and the spring acting as both damping and flexible elements at the same time, structural and kinematic elements.  The main components of this structure are:  Sheet metal lower control arm with Reinforcements which is considerably lighter in weight as compared to forged lower link.  Suspension bushes have been exclusively designed to improve the comfort, adopted asymmetric stiff- ness for the rear LCA bush to reduce the impact harness during acceleration and braking.  Vertical member design acts as sub frame and increases suspension structural rigidity, thus improving vehicle NVH & high speed handling. Vertical member suppresses the acoustic excitation of the body struc- ture generated by the road undulation.  “Dual path” top mount for improved filtering of road vibrations and noise at the same time guaranteeing excellent structural strength favoring driving precision.  Anti-roll bar with Stab link mounted on the shock absorbers that allow improved stabilizing efficiency and better dynamic responsiveness around bends.  Double acting telescopic hydraulic shock absorbers with improved lateral rigidity assisting road hold- ing during cornering. Valve assemblies have been selected for excellent vibration damping.
