Coming from Tamiya and made for the TA07 4WD touring car are several new option parts such as a front 1-way, an aluminium servo mount and aluminium motor mount posts. Starting with the 1-way, using the unit improves acceleration and corner speed at the expense of slightly less braking performance. The 1-way includes a 37T belt pulley, it is compatible with all TA07 Pro cars and it is recommended especially for stock racing classes.
Also new is the lightweight aluminium servo mount. Designed to replace the standard plastic kit part the alloy option offers greater stability for reduced flex and a more direct steering feel. The part comes machined from high-quality aluminium, it is blue anodised and fits all TA07 Pro cars. Last but not least are the aluminium motor mount posts. Coming in pairs they replace the kit standard plastic parts that attach to the main motor plate for increased rigidity and support when using high powered motors.
