Handling and adjustment guide

The Yokomo D-156UM is a front upper mount created for the DPR series upper A-arm, with six selectable pivot positions to modify the upper link geometry. It is suited for RC drift package set-ups and fits both the DP-DPRA and DP-DPRH chassis.

Altering the pivot point shifts roll center and link leverage incrementally, which changes initial steering character and transient roll during cornering. Tuning strategy should focus on one adjustment at a time and record the vehicle response to each change.

Installation involves replacing the stock upper mount on the DPR upper A-arm and using the original chassis mounting points. Basic suspension tools are sufficient; always verify full range of arm movement and steering clearance before full-speed testing.

Compatibility

  • DP-DPRA
  • DP-DPRH
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does changing upper pivot affect turn-in?

Raising or lowering the pivot changes the initial steering bite; small moves can sharpen or soften turn-in depending on setup.

Should I pair pivot changes with other setup tweaks?

Yes, combine pivot adjustments with roll stiffness, toe, and shock settings to achieve a coherent handling balance.

What is the best process for validating a new pivot setting?

Test the car over consistent laps, note steering and mid-corner stability, then revert or progress based on measurable changes in feel and lap consistency.
