Kyosho TF003 Carbon Front Shock Stay TF-5

This is the carbon front shock stay for the Kyosho TF-5 touring car.

The shock stay is the tower the upper ends of both front shocks bolt to, so it anchors the front damping system. Its rigidity matters directly: a stay that flexes absorbs part of every damping input before it reaches the chassis, and it can let the two shocks work at slightly different rates side to side, which makes the car turn in differently left versus right in a way that is very hard to diagnose.

Carbon is why this one is stiff. On a touring car, where precision and repeatability are the whole point, removing that flex means your damping and shock position changes produce what you expect rather than being partly absorbed by the mount.

It also sets the upper shock mounting positions, which is what you move to change front roll and steering response.

Important fitment note: Kyosho states explicitly that this part cannot be used on the TF-5S. It is for the original TF-5 chassis. The TF-5S and Readyset cars use a different stay, so confirm which version you have before ordering.
