Camber Adjustable Lateral Links
Aftermarket lateral links can add both camber and additional toe adjustment to your car. There is no camber adjustment from the factory. If you run coilovers that allow the use of camber plates that is usually the better, more cost-effective way of addressing camber adjustment, but this is another good way. Lateral links are more exposed to the elements than a camber plate, but usually this is okay with a good quality turnbuckle. Upgrading lateral links has the added benefit of reducing unwanted suspension movement and play for better handling, but it does have a disadvantage which is added weight. This is particularly true on a GD STi which has very lightweight factory lateral links.
