Caster Shims, pair

Long ago, car enthusiasts discovered that going faster or lowering a car causes the caster angle to change, causing the car to wander, particularly at high speeds.  If you install these shims under the front beam, the caster angle can be changed, allowing tremendous handling improvements and straighter driving.  These are super easy to install, and only take a few minutes.  Some guys, when running very low, or very fast, stack two pairs of these under the lower beam for even more improvement in steering at high speeds.  When installing one set, you can generally re-use your stock beam bolts.  When installing two (or more) sets, we recommend replacing the stock bolts with the longer 22-2816 caster shim bolts that we also carry.
