Aluminum rear-front 1-piece suspension holder was redesigned to permit mounting of rear bulkheads in to the owner for improved flex of the rear suspension. The 1-piece holder is placed in to the framework for a better centering. The rear supply mounts had been redesigned to utilize the square composite bushings from the T4 and XB4 cars. The square eccentric bushings wthhold the vertical adjustment for the inner hinge pins through the previous NT1ââ¬â¢s, but add the ability to adjust the pin width to grow the roll center and geometry corrections readily available for the rear suspension. The holders may narrower makes it possible for to mount the hands more closer together to create more traction. Ebony color.
