The Tamiya 84402 Titanium Screw Set is tailored for the TRF419 and provides a practical route to lower vehicle weight. The set includes 97 titanium screws across multiple lengths and head types, offering savings versus steel equivalents.
These titanium fasteners are suitable for the TRF419 chassis and work well when optimising weight distribution. Titanium hardware can help with traction and responsiveness on race layouts. Fit using a 2mm hex key for accuracy and to prevent cam-out.
Reducing unsprung and overall weight helps the car react faster to steering inputs. Replacing steel screws with titanium can make the chassis feel more agile and easier to place on corner exits in club and national competitions.
