Koswork Kyosho Front 1.3mm Softer Mid Optima RC Stabiliser Bar - KOS04305-F1.3

The Koswork KOS04305-F1.3 is a 1.3mm front stabilizer anti-roll bar designed as a softer-rate option for the Kyosho Mid Optima buggy. Anti-roll bars directly influence how the car transfers weight during cornering — a softer front bar like this one reduces front end resistance to body roll, which can help dial in balance and steering feel on loose or uneven surfaces. If you're tuning your Mid Optima and want more front grip or a freer-feeling front end, this is a straightforward suspension adjustment to explore.

Key Features

• 1.3mm diameter bar provides a softer spring rate than stock, giving more front axle independence during cornering

• Swapping to a softer front anti-roll bar is a common tuning step when the front end feels tight or the car pushes wide on corner entry
