heating springs?

i heard you can heat the springs with blocks under the car to lower the car. how do i know how much heat to put on it, without weakening or cutting the springs? also, anybody have any tips on this? i dont wanna mess anything up. thanks.

I have a tip...don't do it. It will only cause major problems down the road.

What model cuttlass do you have? What year?

Heating the springs will just weaken them and they will break with use
