Sagami RC Fab has released a new front lower arm, with a shorter wheelbase, for the Awesomatix A12. By using this lower arm the wheelbase will be shortened by 6mm, the turning ability of the car will be improved and cornering will become more agile. By revising the shape and material, the rigidity is slightly lower than the genuine Awesomatix product, so the car can follow the road surface more flexibly. There are also holes for additional servo posts, which allows the rigidity of the suspension arm to be adjusted. Finally, as there are specific mounting holes for Sanwa and KO servos you can set the optimum Ackerman for each. Servos made by other manufacturers can also be installed using two long holes. When using a knuckle arm with zero-trail, the wheelbase will be 3mm shorter than standard, so the Ackerman will also change.
