Tune Steering Response on MR-03 with Kyosho MZW445B

The Kyosho MZW445B upper arm kit is made for the MR-03 chassis and lets hobbyists adjust caster to match handling goals. The set supports three discrete caster angles: 1 degree, 2 degrees, and 3 degrees, giving a quick way to alter steering weight and mid-corner behaviour without complex setup changes.
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.

Will changing caster affect tyre wear?

Caster changes mainly influence steering and load through the front tyres. While not the main factor in tyre wear, altered steering characteristics can change how tyres scrub in corners, so monitor wear after adjustments.

Can I swap caster settings trackside?

Yes, the discrete settings let you try different angles between runs. Bring basic tools and double-check fasteners after each change before you go back out.

Is the MZW445B compatible with all MR-03 variants?

The set is specifically designed for MR-03 chassis layouts. Confirm fit on your MR-03 variant and refer to chassis documentation if you run a heavily modified car.

Any setup tips when changing caster?

After changing caster, re-check toe and camber, and perform a short test run. Adjust small increments and note lap times or handling notes to find the right setting.
