The adjustable version is only available from SuperPro and it is supposed to cost extra than the regular ones. We just threw them in at no extra cost and they help you adjust camber without the need of camber adjusting bolts. The crush tube has an offset hole, so once the bolt goes through you can rotate it inwards and outwards by simply loosening it and pulling/pushing the tire. Its the same principle as the camber adjusting bolts that you would just turn, except the offset belongs to the crush tube instead of the bolt. It's much stronger than the camber adjusting bolts because those must be undersized to accommodate the offset, and they tend to snap in hard cornering because of that.
