Aluminum rear lower suspension owner for the BACK of this rear bulkhead, CNC-machined from premium Swiss 7075 T6 aluminum. Made to wthhold the well-proven geometry of the NT1. Suspension holders enable more durable mounting of the suspension hands. Utilizing the suspension holders, the geometry for the vehicle cannot alter even after difficult crashes. Because of the mounting system, hands move extremely easily which provides greater traction plus the car seems smoother in corners. The rear supply mounts had been redesigned to make use of the square composite bushings from the T4 and XB4 vehicles. The square eccentric bushings retain the vertical adjustment for the inner hinge pins from past NT1s, but add the ability to adjust the pin width to expand the roll center and geometry adjustments readily available for the trunk suspension system. The holders are also narrower which allows to install the hands more closer together to build more traction
