Aluminum Lower Caster Block 12 degree Red (for DRB/DIB) YOKIB41312R Yokomo  [YOKIB41312R]

Overview of the aluminium lower caster block

The Yokomo YOKIB41312R lower caster block is an aluminium suspension component made for DRB and DIB chassis configurations. In red, it delivers a fixed 12 degree caster at the lower pivot point to alter front steering characteristics on touring car models.

Functionally the block defines the lower suspension pivot location, establishing a caster angle that influences steering feel and weight transfer across the front axle. Fitted on DRB or DIB platforms it creates a reliable geometry reference for progressive setup adjustments.

Fitment guidance: mount this block at the lower caster position and replace the factory lower block on DRB/DIB suspension assemblies. There are no extra items noted here; use the original mounting bolts and adhere to the chassis manufacturer's torque recommendations.

As a straightforward geometry component for DRB and DIB cars, this lower caster block suits modelers who want a consistent caster baseline to explore handling changes and improve turn-in precision.
