Black steel strut brace for Opel Corsa B — TA Technix

The brace connects the two shock absorber mounts. In a hard corner, the loaded side of the suspension pushes outward and the geometry deteriorates precisely when you need it most: the brace distributes the load between both sides.

The front end becomes more precise when turning in, and the car maintains the same response from one corner to the next. The effect is noticeable on older chassis, convertibles and high-mileage cars; it is more subtle on a modern body that is already rigid.
