This particular strut tower brace is manufactured in China and comes with a 3-year warranty. The Whiteline KSB557 is specifically designed for the BMW E46 3 Series chassis. It fits a wide range of models, including the 323i, 323Ci, 325i, 325xi, 325Ci, 328i, and 328Ci, spanning model years from 1999 through 2006.
