The Kyosho UMW742B Carbon Composite Rear Suspension Arm Set is a straightforward upgrade for RB7 owners who want to refine handling and reduce rotating mass. The carbon composite construction aims to combine durability with a lighter footprint than conventional materials.
Carbon composite brings a high strength-to-weight ratio that helps lower unsprung mass and enhance responsiveness. On the RB7, the UMW742B helps the suspension react faster and keeps tyre contact steadier through transitions.
Designed to the RB7 layout, these arms should install without alteration, giving a hassle-free swap from stock components and preserving existing adjustment ranges.
Whether refining setup for lap time gains or improving component longevity, the UMW742B provides a reliable platform for further tuning and upgrades in competitive settings.
