The BMR single-adjustable lower trailing arm for 2015–2019 Cadillac CTS‑V replaces stock stamped steel arms to minimize control arm flex and reduce deflection. It restores more direct power transfer to the tires and is intended for street performance, drag racing, and road racing. The LTA631 design improves suspension consistency under load for firmer launches and predictable handling.
