The bump stop is a soft limiter for compression travel. It prevents the piston at the end of the shaft inside from bottoming out, which can damage the internals and ruin the damper.

If you trim the bump stops too short, you run the risk of bottoming out the piston over large, fast bumps. A rule of thumb when running dampers with the same body length as stock is to never leave less than 1" of bump stop.

However, if the bump stop is too long, it can limit the compression travel too soon. For example, if you're running lowering springs with rates that are too soft for the ride height, the suspension can compress enough in some circumstances that the car will effectively be sitting on the bump stops - which will cause a very rough and bumpy ride, and can cause erratic handling if the suspension is running into the bump stops mid-corner.

The bump stops don't have to be shortened, but it is usually a good idea to trim at least some off if you're lowering the car. What springs are you running with the Tokico HPs?
