Koswork Kyosho Front 1.2mm Softest RC Stabiliser Bar Mid Optima - KOS04305-F1.2

The Koswork KOS04305-F1.2 is a 1.2mm front stabiliser anti-roll bar designed for the Kyosho Mid Optima, and it is the softest option in the Koswork front bar range for this model. Anti-roll bars directly influence how the car transfers weight during cornering — a softer bar like this 1.2mm version allows more independent suspension movement, which can help maintain traction on bumpy or loose surfaces. If you're finding the front end of your Mid Optima pushing or lacking grip on rough terrain, swapping to a softer front anti-roll bar is a straightforward tuning step that doesn't require major disassembly.
