I've been obsessing over tall T's and the like lately and thinking about buggy sprung suspensions. Independent suspensions were developed when roads were terrible and feedback from ruts and bumps from one side of the car to the other was quite detrimental for comfort and control. Now, the roads I drive are for the most part quite good- lacking substantial surface flaws- and I'm not careening around at the near limits of control so I'm thinking independent suspension front or rear or front and rear is not really needed.
Why do away with independent suspension? Simplicity, weight, cost, room, etc.
