Stance Adjustable Lower Control Arms are made from billet aluminum for strength and durability. The Lower Control arms are used to adjust camber and the range achieved with these is negative 1deg - 6deg. Stance also implements Aurora Rod ends on these arms. The most important part of aftermarket suspension links are the rod ends. Aurora spherical rod ends are one of the most expensive and high quality rod ends on the market, and for good reason. Aurora ends are used in both military and NASA Applications, so their quality pretty much speaks for itself.
Stance actually uses Aurora's 3pcs billet rod end bearings to be exact. Aurora bearings use a sintered steel ball to handle extremely high loads. The Rod ends feature special chemical bonded PTFE liners for smooth operation, less noise, and long life. The rod end housings are heat treated and zinc coated for strength and durability as well.
The Stance Lower Control Arms are designed to raise the hub mounting point about 20mm when compared to stock, which lowers the car about 25mm. This allows for longer stroke dampers found on the Stance FR-S application, and have more height adjustment range. This design is especially helpful for 1-way height adjustable coilovers like KW, which lose stroke as you lower the car.
