Aluminum back reduced suspension system owner the BACKSIDE associated with the rear bulkhead, CNC-machined from premium Swiss 7075 T6 aluminum. Built to retain the well-proven geometry associated with NT1. Suspension holders allow stronger mounting regarding the suspension system arms. With all the suspension system holders, the geometry regarding the vehicle does not alter even after difficult crashes. Thanks to the mounting system, hands move very easily gives higher traction while the vehicle seems smoother in corners. A corner arm mounts had been redesigned to make use of the square composite bushings through the T4 and XB4 automobiles. The square eccentric bushings wthhold the straight modification of internal hinge pins through the previous NT1ââ¬â¢s, but add the ability to adjust the pin width to expand the roll center and geometry alterations available for the rear suspension system. The holders will also be narrower allowing to install the hands more closer together to build more traction. Black color.
