Pre-owned Tein Performance Bar for the Toyota JZS161 Aristo. TEIN Performance Bars are produced by using A6000 aluminum. TEIN has been able to produce bars, which are not only lightweight but are also exceptionally rigid. The twist and flex that occurs in performance driving is reduced, therefore allowing the driver to obtain the full potential of the suspension. Features include green anodized mounting plates, polished aluminum bar, and EDFC compatibility.
