Aluminum straight back repaid suspension system holder the trunk linked to right back bulkhead, CNC-machined from premium Swiss 7075 T6 aluminum. Developed to retain the well-proven geometry of NT1. Suspension holders make it possible for more powerful mounting of suspension system arms. Due to suspension system holders, the geometry regarding car cannot modification despite having hard crashes. Because of the mounting system, hands move extremely efficiently provides greater traction combined with vehicle seems smoother in corners. The trunk supply mounts were redesigned to utilize the square composite bushings through the T4 and XB4 cars. The square eccentric bushings retain the right modification with this interior hinge pins through the previous NT1s, but range from the power to adjust the pin width to cultivate the roll center and geometry customizations intended for the trunk suspension system system. The holders in many cases are narrower permitting to mount the fingers more closer together to build more traction
