SPL Parts 370Z/G37 Rear Toe Arms - Billet VersionFor those who have converted to "true" coilovers in the rear suspension (rear spring relocated over shock) and no longer need the mid link to hold the rear springs, our SPL Parts TITANIUM Series 370Z Rear Toe Arms (RTA) replace the stock mid links to provide a wide range of toe adjustment, which is necessary for lowered cars or for performance alignments. No more jam nuts! Faster, more precise, easier adjustment! Using FEA (Finite Element Analysis)
