The Eibach Camber Bolts are designed for non-slotted struts. This will allow for both positive and negative camber changes up to approximately 1.75 degrees (depending on your vehile) by replacing the OEM strut/spindle bolt.
This is an easy means of adjusting just by rotating the head of the bolt. Each kit comes provided with two cam bolt assemblies which are enough for both sides of the vehicle. These are for the front only on most vehicles.
