Add to Wishlist


If you want your Fiesta ST to handle even better than it already does then the Mishimoto Fiesta ST trunk brace is the way to go. It’s constructed of rigid 14-gauge steel bar with CNC’d steel end plates to keep the rear of your Fiesta ST planted in the corners. Your Fiesta ST’s steering response will be improved due to decreased rear end chassis flex. This a simple yet effective improvement for any Fiesta ST, whether it be a daily driver or track car. You’ll have no issues hauling some cargo in your hot hatch, as this brace takes up very little room and retains the use of the factory false floor. Just like all Mishimoto Fiesta ST parts, this Fiesta ST trunk brace features the unparalleled Mishimoto Lifetime Warranty!
