Koswork Kyosho Front 1.2/1.3/1.5/1.6mm Stabilizer RC Anti-Roll Bar Kit (Mid Optima) - KOS04305-FBAR

The Koswork KOS04305-FBAR front anti-roll bar kit is a direct-fit stabilizer upgrade for the Kyosho Mid Optima, offering a choice of four spring rates — 1.2mm, 1.3mm, 1.5mm, and 1.6mm — so you can dial in front-end roll resistance to suit different track surfaces and driving styles. Having multiple bar thicknesses in a single kit means you can tune the handling balance without ordering separate parts every time conditions change.

Key Features

• Includes four front anti-roll bars in 1.2mm, 1.3mm, 1.5mm, and 1.6mm diameters for a wide range of roll stiffness options
• Thicker bars reduce body roll and increase front-end stability; thinner bars allow more suspension travel and compliance on rougher surfaces
• Machined and manufactured by Koswork to fit the Kyosho Mid Optima front suspension geometry
• Compact kit format keeps all four bars together, making track-side tuning straightforward

What's Included

• 4 x front stabilizer anti-roll bars (1.2mm, 1.3mm, 1.5mm, and 1.6mm)

What You Need

• Kyosho Mid Optima RC car (sold separately)
• Basic hand tools for installation (e.g. hex drivers or screwdrivers as required by your build)
