Centro introduce the C.4.1 +8mm extended hard chassis for the popular Team Associated B4 conversion kit. The new chassis is designed to refine the handling, giving more stability and a better balance. The material has also been changed to a harder compound with the overall result giving faster lap times with more consistency. To compliment the chassis, the battery brace has been re-designed to account for the extra length. As well as the option to move the original fitting for saddle pack cells into a forward or rearward position, the brace is now wider and longer to allow for ‘Shorty’ packs to also be fitted, either across the chassis or lengthways to give the racer increased options for chassis layout and weight distribution. All the original Centro parts will fit this chassis/battery brace so nothing else extra is needed.
