MR..Roche introduce new option parts for the Tamiya TRF417V5, TA05 and TA06 touring cars as well as the Kyosho RB6 buggy. Starting with the Tamiya options, available now are specific heady duty differential cup joints that are made from ultra-hard spring steel to increase the lifespan. The drivetrain parts received a heat treatment for an even harder surface and the TA05/06 parts also include POM low-friction joint shaft blades. Swinging over to the RB6 parts, MR..Roche come up with a battery plate, ESC mount plate and a 4mm front shock tower. All parts are CNC-machined from high-quality carbon fibre with the battery plate and shock tower also sporting milled out sections for an even lower weight and good looks. All parts are a direct replacement for the stock plastic composite items.
