The Tamiya 49345 TB Evolution IV Titanium Screw Set replaces standard hardware with lighter titanium fasteners to reduce chassis weight while keeping secure joints. Produced from durable titanium, these screws deliver roughly a 50% reduction in fastener weight compared with stock parts, which can improve steering response and acceleration on track days.
Titanium combines low mass with strong mechanical properties, making it ideal for race-focused upgrades. Fitting this set to a TB Evolution IV enhances handling precision and helps maintain component integrity over many running sessions. It is suitable for drivers seeking consistent performance improvements.
Installation requires only standard tools and minimal time, offering a quick route to a lighter build. The Tamiya 49345 screws work well alongside suspension and drivetrain tweaks to refine vehicle behaviour.
