SCT Inner Sidewall Support Adaptor for JC SCT Tires (JCO5013)

Inner Sidewall Support Adaptor for JC SCT tires is designed to stiffen the tire’s inner sidewall, reducing deflection under high traction for steadier turns and more consistent handling on the track. The adaptor is glued into place on the inner sidewall of JC SCT tires to increase rigidity where it matters most.

Used in competition, it helps the tire maintain control on glued, sealed, or naturally grippy surfaces and delivers smoother, more predictable performance on rough, dusty, or uneven tracks. By expanding setup options across a variety of surfaces, it provides drivers with a broader tuning window to optimize cornering and arc entry.
