X-Factory UK have introduced the DMS Trim2Tune tyre inserts for 1/14th scale micro off-road cars. The idea behind the inserts was that micro racers were always requesting different width inserts to fine-tune the grip levels on their micro buggies to differing tracks. Unlike many other classes the ranges of inserts on offer were quite minimal, so options were greatly reduced. DMS’s open cell inserts come very specifically as 50mm wide as the most popular width in use is still 25mm and for those racers happy with this width, they can simply cut them straight down the middle. For those who wish to create their own width specific to their requirements, they can be trimmed with conventional scissors to any width desired. The inserts come as pair, allowing to cut at least four inserts from a pack and they are available in a soft, medium and firm variant.
