Tighter Control with Kyosho MZW703H Upper Arms

The Kyosho MZW703H Hard Caster Setting Upper Arm Set is built for the MR-04 chassis to enhance steering accuracy and front-end stability. It is aimed at hobbyists who want a more predictable steering response on the circuit.

Improved Corner Response for MR-04

Adding the MZW703H upper arms gives the MR-04 a firmer caster feel that reduces understeer and improves front bite during fast direction changes. The pieces are designed to fit MR-04 mounting points for straightforward installation.

Durability for Regular Use

With sturdy construction, the Kyosho MZW703H Upper Arm Set stands up to frequent driving and keeps alignment precise over time. This makes it a sensible upgrade for drivers who test setups often.
Remark :
Due to limited stock availability, please notice that some Kyosho 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.

Can I fit these to a modified MR-04?

If the MR-04 retains the stock upper arm mounting locations the MZW703H will fit, but custom front assemblies may require bracket checks or shims.

Will this affect tyre wear?

A stiffer caster setup can change how tyres scrub through corners, so monitor wear on the front tyres and tweak toe or camber as needed.

What should I check after fitting the arms?

Check steering endplay, ensure ball stud tightness, and take a few test laps to confirm handling before finalising settings.
