Upper mount design notes

This hard upper A-arm mount fits the R12/GT500 chassis family and is listed as Yokomo part YOKR12-09G. The part swaps into the stock location to provide a firmer pivot, influencing how quickly the car transitions in roll without changing arm length or the main suspension geometry.

The mount is aimed at drivers wanting a more predictable camber curve and tighter transient control during club and competitive sessions at 1/12 scale. It is offered as an aftermarket replacement option for those setup changes.

Fitting requires removing the original mount and attaching this unit to the existing suspension towers and linkages on the R12/GT500. Because the pivot stiffness is increased, run controlled setup laps to assess how the change affects mid-corner and entry behaviour.

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 robust is this mount under frequent track use?

The design focuses on reducing pivot compliance; inspect the mount and fasteners regularly after sessions to confirm there are no stress points or looseness developing from repeated impacts.

Will the harder pivot increase wear on mating parts?

Increasing stiffness can shift loads to surrounding components. Monitor the suspension tower and arm attachment points for wear and service them as part of routine checks.

Should I change maintenance intervals after installing this mount?

It is sensible to shorten initial inspection intervals until you confirm how the mount behaves on your car and track; tighten checks on fasteners and contact surfaces after the first few runs.

Does the mount need special cleaning or protection?

Keep the mounting area free of grit and debris and ensure screw threads are clean and secure. No special treatments are required beyond normal component care.
