    2003 Ford Focus Performance Parts Reviews

    Ford Focus Rear, Upper Control Arms
    These items are much beefier than the stock arms. They are also adjustable. Once the parts are on the car, they can be adjusted without having to disconnect either end. On my 2003 Focus ZX3, the left was much easier than the right to install but they fit perfectly. I would recommend these to anyone that needs to adjust the rear camber.
