- 21. VARIABLE CHAMBER MECHANISM- The variable camber mechanism is a modification in the front suspension design which will allow us to vary the camber angle at will. This is done through using adjustment bolts which will help vary the distance between the upper knuckle joint and the chassis. Camber can be varied in test runs and the optimum camber can be decided for the particular condition. INDEPENDENT FENDERS-The fender is a removable attachment to the A-arms of the suspension which help to block dirt & sludge away from the driver. It is mounted on the A-arms using pipe brackets hence avoiding drilling of any holes. The assembly is spring loaded allowing it to undergo slight deflections and not making it rigid and prone to failure. INNOVATIONS

SAE INDIA BAJA Baja is an inter-collegiate design competition organized by the Society of Automotive Engineering (SAE) Provide Indian students with a standard platform to showcase their talent and potential not only in terms of design and engineering, but also their capability for team-work, entrepreneurial skills and management. The contest challenges each team to function as a firm, whose task is to design, fabricate, market and race-off an off-road vehicle that will be evaluated on a variety of manufacturing angles. The vehicles are judged based on their ability to maneuver and transverse harsh off-road racing course while not succumbing to the rigors of it.
