Part #: 72052. Maximize your suspension setup on the 350Z/370Z and G35/37 with this race - ready set of adjustable rear lower control arms (RLCA), camber lockout plates, and extended - range toe cams from SPC. You can precisely dial in ±3.0˚ of camber and ±2.0˚ of toe. These arms are specially designed for track use. They feature SPC's xAxis sealed flex joints that act like monoballs but have non - metal bushings lasting longer than OE bushings. The combination of xAxis with forged steel receivers and straight - arm construction reduces compliance under load. The included lockout plates replace OE camber cams to lock in your camber. Adjustment Ranges: Camber: ±3.0˚ / Toe: ±2.0˚. Installation time: 0.4 hr/side. You need 1 per axle.

Using these SPC Performance adjustable rear lower control arms is a great way to enhance your vehicle's suspension. To use them, first, make sure you have the right tools. Installation takes about 0.4 hours per side, and you'll need one set per axle. When adjusting, you can set the camber within ±3.0˚ and the toe within ±2.0˚ to get the best performance for your driving needs, whether it's for daily driving or track use. As for maintenance, since the xAxis sealed flex joints have non - metal bushings that last longer than OE bushings, you don't need to worry too much. But it's a good idea to regularly check the arms for any signs of wear or damage. Also, ensure the lockout plates are properly in place to keep your camber locked. If you notice any unusual noises or handling issues, it's time to take a closer look at the arms and make any necessary adjustments.
