The Serpent 803202 Overdrive Gear Conversion Kit is tailored for the Serpent 720 chassis and increases the allowable diameter difference to 3mm instead of the stock 1mm. Running smaller front tyres moderates grip roll through bends and helps the whole set wear more evenly, contributing to consistent lap times.
The 18T overdrive provides a sensible compromise for reducing uneven tyre wear while maintaining an agile and controllable car on corner exit. It is a practical tuning step for drivers chasing reproducible handling at the track.
