The latest Gen 2 arms have no ABS wire bracket. P2M removed it to beef up the tubing. After alignment, you can simply zip - tie the ABS wires to keep them secure. When paired with full adjustable rear suspension links, you get precise control over your car's rear - end suspension geometry. Made from S45C steel tubing, with 3pc teflon - based rod ends and a dust boot, and a thick powder - coated blue finish. For camber adjustment, by default, it can go up to - 6 negative camber.

The default setting goes up to - 6 degrees. For a better track performance, set the camber between - 3 to - 6 degrees. If you want more negative camber, you can remove the jam nuts, but always lock the arms in the shortest position before doing so. As for maintenance, regularly check the steel tubing for any signs of wear or damage. Clean the rod ends and dust boot periodically. The powder - coated blue finish helps protect against rust, but if you notice any chips, you can touch them up to keep the arms in good shape.
