U can change the front lower control arm bushings with ES brand or maybe whiteline. As for the rear lower control arm bushings I think both companies have those as well but not sure. If u want firmness and a decent ride I would get z1 fuca's over the powertrix as they have ES bushings range than the solid race ish bearings. Also rather than those tension rods maybe whiteline bushings?? I've seen people say they make the ride a bit ruff. Where did u get those coilovers?
