The 300$ is with the entire control arm correct? So anyway, the LCAs from the Z32 to G50 are not the same. The BJs are though.The LCA bushings are as well. Buy the Spicer BJs online around $35per , the Bj seats from IoS I think $10per? + replace LCa bushings w/ the nismo ones- about... $15.per side. Aprox 120$ per side? not a very complicated ordeal!
