Aluminum back reduced suspension system holder for the BACK of the back bulkhead, CNC-machined from premium Swiss 7075 T6 aluminum. Built to wthhold the well-proven geometry of the NT1. Suspension holders enable more durable mounting of this suspension arms. Because of the suspension holders, the geometry associated with automobile does not alter even with hard crashes. Thanks to the mounting system, hands move very freely gives higher traction as well as the car feels smoother in corners. The trunk arm mounts had been redesigned to make use of the square composite bushings through the T4 and XB4 vehicles. The square eccentric bushings wthhold the straight modification of the internal hinge pins from the past NT1s, but add the capacity to adjust the pin width to expand the roll center and geometry corrections readily available for the trunk suspension system. The holders may also be narrower allowing to mount the hands more closer together to come up with more traction
