bump stops

[gwako]

I was just wondering what is the reason for cutting bump stops on shocks when installing lowering springs ?

Have you ever ridden in a car that is riding primarilly on bumpstops? It gets REALLY bouncy, so when you lower lower your car, it shortens your strut length which will tend you to be on a closer rate of bottoming out (depending on what kind of setup you have though), so you want a little bit of your bump stock left to prevent your strut from completely bottoming out, but not riding on your spoungy rubber more than the spring... If someone else can clarify for you what I mean, then by all means do it, but i bekeive this is the basic principle of it all.

I really don't understand....what is the reason for cutting it, why don't they just leave it the way it is....

Lets say you lower you car 2" with lowering springs, but you use the same size strut, stock or hopefully aftermarket. You will lose 2" of strut travel because the car is now sitting 2" lower, which compresses the strut 2". By cutting the bump stop you regain some of this lost strut travel because the strut can now compress more before it hits the bump stomp. You don't want to complety remove the bump stop or your strut will bottom out on full compression and ruin the strut. There are some coil-over kits available with shorter struts so you can have both a lower ride hight and plenty of suspension travel.
