Tamiya TB Evolution II Project

The second "evolution" of Tamiya's TB Evolution shaft driven chassis series was released in 2001, only one year after the original.  At first glance, it is virtually the same model with very few visible differences, and in fact all of the plastic parts trees used in the Evo II were carried forward from the original Evo.  So why bother with the new model?  The most significant changes are the machined aluminum parts, not the plastic parts.  The prior plastic bulkheads with integrated suspension mounts were replaced with aluminum bulkheads with separate aluminum suspension mounts.  The plastic camber links were replaced with more traditional threaded rods.  The custom splined universal axles were replaced with CVDs with standard hexes and cross pins.  There were also subtle changes to the dampers, and the cool wheels and sticky tires were replaced with standard dish wheels and slicks.

The TB Evo II is a shaft driven, double deck carbon chassis model with a rear ball differential, front one-way, and aluminum shocks.  There is all wheel double wishbone suspension.  It includes sway bars in both the front and rear.  This model predates the now ubiquitous Tamiya blue anodizing, so the aluminum parts are still just clear anodized.
