The 3Racing Sakura D3 CS SPORT Aluminum Steering Knuckle (SAK-D311/PK) is developed with a focused setup mindset to reduce compliance at the front end and deliver repeatable steering input. Constructed from aluminium to maintain geometry under load, these knuckles help drivers dial in toe and ackermann with more predictable results. They suit racers who prioritise consistent handling and precise feedback for tuning sessions.
