The aluminum front anti-roll bar for the XRAY NT1 allows you to on their own adjust the anti-roll bar from downstop, so that the downstop setting doesn't influence the performance of the anti-roll bar and vice versa.
An added feature with this set usually you can even adjust the wheelbase. The anti-roll bar moves together with the front supply, and wheelbase adjustment shims may be added either in front of the anti-roll club (to shorten the wheelbase) or behind the supply (to lengthen the wheelbase).
