3Racing's Cero Ultra Ver 2.0 is 3Racing's latest competition on-road touring car chassis kit. The main improvement of the Cero Ultra 2.0 is to use a shorter and narrower chassis to improve the frame's cornering efficiency.
With the belt length of S3M345 x2, using this shorter belt to achieve a shorter chassis and more direct acceleration output. The front and rear lower wishbones have been carefully improved to more room for the anti-roll bar movement and a shorter wheelbase.
The lay-down front and rear absorbers mounting make the body roll more efficient, the main chassis has a new weight distribution position and a shorty battery socket, and the diameter of the lower wishbones rolling shims has been increased to improve the durability of the chassis plate.
Caster has been added to the rear upright to increase the speed of all corners, and the steering system has changed to M4 X 7 bearings. To improve accuracy, the upper deck was shortened to accommodate the twist of the frame.
