For racers wanting crisper handling, the 3Racing SAK-XS307C Sakura XI bottom cap is a focused upgrade. Made to match the SAK-XS307C chassis, it helps limit flex and protects mounting points to keep your car reliable on race day.
The 3Racing bottom cap seats cleanly against the SAK-XS307C chassis and adds reinforcement where flex is most likely. That firmer platform supports predictable steering response and stability under braking.
