This vital connection between the sway bar and the trailing arm is often overlooked when building the suspension on your MINI. This is especially unfortunate as even the best sway bar, best tires, etc. will be underused and depreciated without this simple and inexpensive upgrade. OEM endlinks are known to flex or fail with upgraded sway bars. ALTA endlinks provide a solid No-Flex connection between your sway bar and chassis which translates into a more predictable handling car.
