Product Details

The Wisefab Front E90 Steering Rack Conversion Kit for the 2015-2023 Ford Mustang (S550) relocates the factory steering rack to correct Ackermann geometry when running a Wisefab angle kit. By moving the rack rather than shimming it, this S550 rack kit delivers rigid mounting, sharper on-center feel, and improved steering precision at full lock.

Engineered in Estonia by Wisefab — the chassis-engineering house behind many of the world's top-level drift cars — every component is spare-parts-supported and designed to integrate cleanly with the broader Wisefab S550 platform.
