Tuning Impact of the YR-10US on YR-10F

This graphite front upper arm support is intended for 1/10 scale formula cars and matches the YR-10F chassis. Fitted as an upgrade it delivers a firmer mounting point than the stock plastic piece, which changes how the front end reacts to inputs.

The part mounts at the front upper arm pivot and works with the existing arm pins and hardware on YR-10F configurations. Installation usually involves removing the front suspension to access the upper arm mounts, verifying correct alignment, and confirming smooth travel after reassembly.

From a setup viewpoint, a graphite support raises the local stiffness at the upper link, reducing flex during high load and sharpening initial steering. Many racers add it to get a more predictable balance when dialing in camber and roll centre adjustments.

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 will this change initial turn-in and mid-corner feel?

Expect a crisper turn-in due to reduced local flex at the upper mount, while mid-corner stability improves as geometry holds more consistently under load.

Should I alter other setup items after fitting?

You may need to tweak camber or anti-squat settings slightly because the change in stiffness can affect how the tyre contact patch behaves; small incremental adjustments are recommended.

Does it affect ride height or droop?

The part itself does not change static ride height, but by reducing flex it can alter dynamic droop characteristics, so recheck droop settings after installation.
