Heat is bad for springs. They lose their temper and start to sag a little more every day until they don't work at all. You'll be bouncing all over the road eventually.
Although not ideal, it is
better to take them out and cut a coil or two off than it is to heat them.
I respectfully have to disagree with 100% of this post, lolol. I heated my first set of springs on my 1980 Datsun 210 SW back in 1986. I've never looked back. I've owned about 30 cars or so...all of which I heated the springs on. Even now, 25 years later, I have 2 cars (both dailies) that are on heated springs. And I'm not talking an inch or two. I'm talking full on heating about 4-5 coils on each corner, lolol. I have NEVER had a suspension problem with ANY car I've owned with this method. I have never replaced a spring. They were the original springs that came on the car and never once did I have an issue. As far as ride quality goes, it's a much smoother ride on heat than cut. I'm also old school going back to when after market springs weren't available or readily available.
This is all based on my experiences and the experiences of the dozens of people of whose cars I lowered by this style.
