cutting springs is a baaaaad idea.. if you cut them too short, they dont resist bounce more just because there shorter.. they actually bounce just as much, all you have done is made your chances of bottoming out a lot higher. the spring has a sprung weight.. and when you cut them, the sprung weight is the same but it has less distance to compress, so you will either bottom the springs out or bottom the car out tearing up your cradle, tranny, rear end, exhaust, fuel and or brake lines... cutting springs is a bad idea, wait till you save the money for some shorter aftermarket springs.
