It gives you more travel in the suspension, I had to cut of the bottom half of the bump stops. If you dont cut it you will be bottoming out a whole lot more. Someone correct me if Im wrong.

From what i know if you don't cut it and if you're low enough you will have a crappy ride. Bouncing all around like you have hydros

Here is a better solution: Get some Bilstein Sport shocks.

The bump stops aren't the culprit from having a crappy ride. It's the fact that you're lowered too much on OEM shocks to have any real suspension travel. The bump stops are there for a reason. I rather hit that than have internal shock damage.


Either get some Bilstein Sport shocks, or get coilovers that lowers independent of preload.



If you must cut the bump stop, dont cut it too much. The less material there is, the less it'll handle the compression, but I guess you do gain a bit more travel assuming the internal shaft isn't hitting anything.

Bump stops are your friend.
