how to stiffen springs

how do you stiffen up a pair of front coil springs? i bought a set of 3" lowering springs for my 66 impala. look is good but exhaust scrapes a lil on bumps. if i could stiffen the springs a lil it will fix it.

You could always try those getto "spring rubbers". Should be able to find them at autozone and the like (most likely won't find them at a good parts store) for about $5.

Did you install new/any isolators when you put the springs in? They go up top in the coil bucket. Replacing your old ones might get you a smidge more ride height (but won't stiffen it at all)

You put lowering springs in it, and now you complain that it's too low..................I think the answer is obvious.

the only place that hits the ground on a good bump s the header collector. I luv the way the car sits right now just would like a little stiffer spring so it won't bottom out so easy. thanks guys

That being the case you might want to look into bump stops. The old fashion solid rubber bump stops are not what I would use. A good bump stop example would be the ones used on S10 ZQ8 trucks front suspension. These trucks came lowered 2" from the factory. They came with polyurethane foam bump stops that almost touch at ride height. Unlike solid rubber bump stops they start out very soft and get much stiffer very quickly. They go for about $20 each at a GM dealer (you can only get them at a GM dealer!) and have a stud sticking out of the metal bracket making them very easy to mount. Your car will still ride nice but not bottom out.
