I would like to start a technical article on the advantages/disadvantages of an IRS equipped quad versus and SRA equipped quad.
I would request that any posts are informative and valid and that everyones opinion is respected as long as it is based on fact.
I would first like to clarify goal of a suspension system: To ensure vehicle stability under any circumstance associated with accelerating, cornering, and braking while avoiding any undesirable movement.
The double wishbone rear suspension has many advantages and some disadvantages compared to a live rear axle.
It allows for increased tuning capabilities including camber, caster, toe etc....
Increasing negative camber gains all the way to full suspension travel. Can be very useful on uneven terrain.
It is more complex and currently weighs slightly more. The design of an dual a-arm setup compared to an axle actually reduces unsprung weight allowing the suspension components to function at a higher level.
Also, without a very stiff anti-sway bar torsional rigidity is reduced producing more body roll. Can be remedied by the addition of a very stiff and rigid anti-sway bar and the shock mounts seem as if it would be a great place to mount one.
