Product overview and purpose

This hard upper A-arm mount fits the R12/GT500 chassis and is catalogued as Yokomo YOKR12-09G. The unit replaces the stock upper mount to provide a firmer pivot point that influences suspension response without changing arm length or primary geometry.

Offered as an aftermarket replacement, the mount is suitable for drivers seeking improved camber control and a more decisive roll feel during 1/12 scale track sessions.

Fitment involves removing the original upper arm mount and securing this part to the existing suspension towers and linkages on the R12/GT500. Because the pivot stiffness is altered, carry out measured setup tests to judge handling effects and trade-offs.

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.

Is this mount interchangeable between R12 and GT500 variants?

It is specified for both R12 and GT500 chassis lines. Confirm the specific year or submodel mounting points if your car has non-standard tower alterations.

Do I need to alter arm length or geometry after fitting?

No change to arm length or basic geometry is required; the part modifies pivot stiffness rather than altering mounting positions or arm dimensions.

How can I verify correct fit before running the car?

Dry-fit the mount to confirm alignment with the arm and tower holes, then check for smooth articulation and correct fastener engagement before track testing.

Are there any known incompatibilities with popular third-party parts?

Compatibility depends on third-party arm and tower geometry. The mount is guaranteed for original-spec R12/GT500 arms; when mixing parts, verify fitment and clearance prior to use.
