This kit contains lower and upper chassis, steering conversion and other accessories. All parts are made of CNC machined carbon plate 2,5 mm thick. With this kit, you can change battery position to achieve required weight distribution and better steering performance is achieved as well. Additional modification of other chassis parts may be required for best performance (not neccesary). Shape of the parts can be slightly modified (updated versions). Lower chassis plate. Front and rear spacer for lower plate. Knuckle arms levers/extenders. Threaded steering rods. 12 pcs M3 nuts. Please check first, that you have Tamiya TA02. Distance on your original chassis mounting holes should be 208mm. Otherwise you have probably TA01 which has longer chassis. Every order is tracked, but I don’t provide tracking numbers unless there is some problem or delay. Thank you for understanding.
