Solid Rear Subframe Riser Bushes for NissanThese solid rear subframe bushes replace the stock rubber bushes. They prevent movement of the subframe and correct the roll center by about 15 mm. For seriously lowered vehicles they ensure a better alignment and allow for the suspension to work optimally. Drifting puts lots of pressure on the stock bushes that become worn out and spongy over time causing the subframe to move around and become noisy especially if your vehicle has a welded differential.These aluminium bushes made by SuperForma and are compatible with Nissan 200SX S13 S14 S15 and Skyline R32 R33 R34 300ZX Z32.... The subframe will need removing for installation.
