The Tamiya 54420 titanium screw set is specified for TRF201, TRF511, TRF502 and XV-01 chassis where 2.6x5mm fasteners are required. These titanium screws replace heavier steel parts to reduce weight at key attachment points while keeping secure clamping.
Titanium offers an excellent strength to weight ratio, so installing these screws can sharpen handling and improve response without compromising component reliability. They are a sensible upgrade for drivers tuning for lap time or feel.
The Tamiya 54420 set suits the TRF models listed above and is best used in suspension and linkage locations that benefit from lighter hardware. Always confirm the 2.6x5mm size matches the target screw hole before fitting.
