The rear subframe mounts on the RNN14 Pulsar GTiR are notorious for flexing under the car’s high-torque AWD system, especially when modified or driven hard. SuperPro’s Subframe Mount Bushing Kit (part SPF3774K) replaces the soft factory rubber with high-performance polyurethane shell bushings that dramatically increase rear chassis rigidity, reduce drivetrain shift, and deliver more direct power to the ground.
This upgrade minimizes wheel hop, sharpens rear-end response, and improves overall traction and handling precision — making it a must-have for serious street, track, or rally Pulsar GTiR builds.
