BAJA ASIA 2010

Team : SOULREAPERS College: S.K.N.C.O.E. Team leader: PADAMSINH PATIL

Responsibilities Vehicle has been designed as per baja rulebook specifications. No component of vehicle would be manufactured outside college or from a professional person. Safety of driver was kept as prime concern while designing.

Goals Build a strong chassis that will endure the rugged environment at the Baja competition Follow all SAE Competition Rules Reduce the weight of last years chassis Increase accessibility of cockpit Improvement in suspension Try to achieve better position than last years ranking
