After unbolting the top mount for the factory shock from inside the trunk, the mount is slid into the hole. Some excess seam sealer may need to be removed so that the coilover mounting bracket slides into place without forcing. These brackets slightly relocate the coilover mounting position to ensure sufficient clearance for 18x10.5-inch wheels and 315mm tires. The bracket is designed to properly distribute the coilover loads into the unibody mounting pad. Years of testing on CorteX-prepped race cars has proven the design’s extreme durability.
