I'm running BMR boxed lower rear control arms and tubular upper arms on both of my cars. They are high quality and affordably priced. If you get poly bushings in them they have greasable fittings. However, I have yet to figure out how to grease the lower control arm fittings that are closest to the frame. The grease gun fitting will not clear the control arms/frame. So, be sure to grease them before installing them on the car.
