I did use those. Only thing I changed was the rear bushings, and I replaced them with polyurethane. I'm still using them, with no warranty issues. Only thing I wish I had done was replace the ball joints with Moog or something a little better before I put the arms on the car, just because it was a ***** and a half to get the bushings lined up when I installed, and it's a million times easier to change the ball joints to the bolt- in style while the arms are off the car.
Did you use the ebay control arms? How did they/are they holding up? Are the ball joints and bushing good did they hold up. Did you need to warranty them? 4PC FRONT LOWER R/L CONTROL ARMS WITH NON TEAR BUSHINGS AND FRONT SWAY BAR LINKS | eBay
