Part #: 666 477 A. Cusco presents two versions of front lower arm braces made from high - tension, lightweight aluminum. The Type 1 brace, ideal for street cars, bolts to the lower arm at two points, greatly enhancing chassis rigidity without excessive stiffness. The Type 2, designed for cars with lots of track time, connects at multiple points on the lower arm for maximum chassis support. No matter which type you pick, you'll be satisfied.
Using this Cusco front lower arm bar is straightforward. First, make sure your car is the 2002 - 2007 Subaru WRX or STI. If you choose the Type 1, find the two connection points on the lower arm and bolt it on. For the Type 2, connect it at the multiple pre - determined points. When installing, ensure the bolts are tightened properly but don't over - tighten. As for maintenance, regularly check the bolts for any looseness, especially after driving on rough roads or using the car on the track. Clean the bar with a mild soap and water solution to keep it in good condition.
