Baja SAE is a collegiate student design competition, in which students design, manufacture, and compete with their vehicle in off-road terrain conditions. All competing vehicles are limited to a 10 hp. Briggs & Stratton engine, in which performance modifications to the engine are strongly prohibited. This design was to be used on our competition vehicle for the Baja SAE 2016 competition. Unfortunately, the vehicle was unable to be constructed in time for competition.
For this front suspension, as well as for the rest of the vehicle, a limited budget dictated design considerations. Therefore, it was elected to use as much readily-available and used-condition components where applicable. With this consideration in mind, the components from a Polaris Outlaw 525 IRS atv were considered to be the best available option for our application. This means that the front hubs, front uprights, front ball joints, and front brake rotor and calipers were to be used from this model of quad.

Rims: Douglas Wheel A5, 4x156mm bolt pattern, 10" x 5" wheel dimensions, 4" backspacing
