For Mini-Z racers focused on consistency, the Kyosho MZW706N Aluminium Upper Brace adds targeted stiffness to the MR-04 chassis. The result is reduced twist under load and crisper steering feedback at higher speeds.
Swapping to an aluminium upper brace reduces chassis flex that can blur steering inputs. On the MR-04 the MZW706N helps maintain wheel alignment during aggressive cornering, making the car easier to place lap after lap.
Fit the MZW706N using an even torque pattern on the screws and recheck alignment after a test session. It pairs well with upgraded arms and hardened mounting hardware when pursuing a low-deflection race setup.
Kyosho produces parts to tight tolerances so the MZW706N slots into the MR-04 with no fuss. Its anodised finish resists wear while keeping the added mass to a minimum for preserved agility.
The Kyosho MZW706N Aluminium Upper Brace is a focused upgrade for MR-04 owners wanting firmer chassis behaviour without compromising the Mini-Zs trademark agility.
