Has anyone found stock appearing rear springs with heights less than stock available? I dropped the front, but the rear didn't change and it's way to high. I don't want to soften the stock springs because I'll get an unpredictable rear spring weight. Any ideas?

I cut my rear springs with a port-a band saw to get them to the height I wanted.that way you don't mess up the spring rate as you would with heat.

MAN, we are needing taller springs in our car. We are running 12 in. springs and still looks like we are dragging the ground.

I can't cut the springs, they're smaller at the ends, I have to use stock configuration springs or stock appearing, I think they're 14" in free height.

Just cut the top coils off. It will sit in the stock pockets just fine.

What's everyone running in the rear as far as spring rate?

my car works great with a little stiffer spring. I run 300 and 250 in the rear with 1100 and 1250 in the front. This is on a '81 Malibu. We run on 2 diff. tracks. One is a big half mile with long sraits and tight turns, the other is a small 3/8 or big 1/4, nobody knows for sure. We use the same setup for both tracks and it works for us

I cut about a half a coil off of the top of the rear springs and the rie height is much better, however the diameter of the spring now allows it to move around against the mount. Do the afco springs have this same problem??

mine move around some to I put clamp around the bottom so they won't fall out. I use a muffler bracket the ones with hole in it the whole lentgh. that's just so I don't loose them. they haven't fallen out yet. knock on wood.

If you cut coils off your springs you will increase the spring rate per inch. Sorry you ruined your springs.

Glad you brought that to my attention Ive been cutting springs on stock cars for 12yrs and I have lost count on how many races Ive won I do have one championship 6 top 3s and started traveling around after that all on ruined springs... guys dont believe everything you read on hear it does change the rate some but I doubt 9 out of 10 times you can feal the rate change as usuall this is just my opinion....Towman

Cutting with a chop saw won't change the rate very much,the heat is where you can ruin the spring,the cutting torch will definitely ruin them.

It is a safe assumption that cutting your springs will stiffen the spring, in propartion the rate, for example, cutting a 200# spring by one coil will change the rate with the approximate ratio as cutting a 300# spring by one coil. The point is, cutting a 200# spring won't increase the rate enough to cause the spring to have a rate greater than the next available rated spring. And you rock towman!
