The aluminum front anti-roll club for the XRAY NT1 lets you independently adjust the anti-roll bar from downstop, so your downstop setting doesn't influence the performance for the anti-roll club and vice versa.
An added function using this set often you may also adjust the wheelbase. The anti-roll club techniques alongside the front supply, and wheelbase modification shims may be added either in front of the anti-roll club (to reduce the wheelbase) or behind the supply (to lengthen the wheelbase).
