Roche have introduced two new items for touring car, the first is this set of aluminium body height adjuster, the idea for which came from factory driver Elliott Harper. The adjuster makes it easier to adjust the height of the body shell, from 0-5mm. There is a 1mm o-ring inside the adjuster so that it will not change height during use. Three colours are available, blue, purple & titanium, to suit all cars with a 6mm body post. Also new for the Tamiya TRF417 is an aluminum anti-roll bar mount. CNC-machined from 6061 T6 aluminium, the roll-bar is centered by a 4mm rod stopper and the tension on the roll bar is adjusted by the 3mm set screw on both sides of the holder. With perfect alignment and a harder material than the original plastic material mounts, the roll bar will always function freely.
