I drive a stock suspension LS. Once of my friends cut his springs, cause he's a cheap bastard. Now his ride is bumpy and unpleasant. We went to a local meet, and they told him he should of heated them. What dose heating a spring do?

 

dont cut springs ever..........and dont heat springs ever.........replace them

o ya and heating it will warp the springs....

 

X2..

 

I WONT EVEN DARE. THATS STRAIGHT RICE AS HELL. But what does heating them do?

 

just cut one coil no big deal i did it and it works fine except the rear will flop around on full droop , so i went to Eibach better with no issues. but as a cheap fix cutting one coil works....

 

cheap fix more like cheap way to mess ur ride up

and heating the springs is like heating any metal........IT WILL WARP

 

It doesnt mess up your ride anymore than putting in stiff lowering springs. Cutting a coil lowers the car by however much you cut off, and it als INCREASES the stiffnes of the spring in proportion to how many coils you cut off of the total. Big problem is that once you do this on an LS/LT your stock dampers dont have enough force to control the new stiffer springs youve got, so you get a bouncy ride, made even worse if youre so low you hit the bump stops

Heating a spring weakens it and allows it to take a new position. Very hard to get any kind of repeatable results with a torch though.

 

where's +rep when you need it?

 

why did your friend do that..he shouldv'e got some nice spring and some decent struts unstead of doing that

 

Wow, not to be a dick, but that is being thrifty as ****.

It'll bite him in the ass one day.

 

cutting a spring with a band saw is fine. not everyone is made of money and it works the ride is not a lot different to the eibachs. i rated springs versus cut springs. here is the rate scoop, real data so please stop slamming the guy ... read the columns, they are hard to read as the site pulls the spacing away...the un cut ss sc spring end at 7.5 inch compression...... from left to right, travel/ rate uncut / rate cut.

Front:
cobalt uncut cut
Travel rate rate
12.00” 0
10.50 250
10.00 260 0
9.0 410 300
8.0 570 450
7.5 650
7.0 620
6.5 740

The tester ran out of travel at 7.5 inches, the cut spring could only start at a lower height and ended at 6.5 inches, so free length is cut 1 inch, ride height went from 26.75 to 26.5 fender to ground through axle center line, rate jumped almost a hundred lbs at full compression....
