510 Bomber Posted July 2, 2011 Report Share Posted July 2, 2011 so i want to lower my 1978 510 hatchback. and im just gonnna cut my coils. i wanna do 1 on each, but does anyone know the formula on cutin coils to inches dropped. thanks for the input 1 Quote Link to comment
H5WAGON Posted July 2, 2011 Report Share Posted July 2, 2011 I understand wanting it lower, but if you cant do it right with different springs or modded struts, you may get a sloppy suspension. But if you still want to do it, remember once you cut, its done. Start small, and whats in back coils, leaf springs? I did my 1st 510 by cutting coils, it was slammed and rode like shit, but I loved it bumps and all....:P I lived in Phoenix at the time, late night drives outside the city......All I can say is Cattle Guards.......Hold on!!!:blink: Quote Link to comment
ggzilla Posted July 2, 2011 Report Share Posted July 2, 2011 There is no formula. Quote Link to comment
datzenmike Posted July 2, 2011 Report Share Posted July 2, 2011 so i want to lower my 1978 510 hatchback. and im just gonnna cut my coils. i wanna do 1 on each, but does anyone know the formula on cutin coils to inches dropped. thanks for the input There are formula for working the spring rate Too complicated to work out the new ride height. You would need the new spring rate and the weight of the car on that corner. And then it would be approximate. Cut sparingly and check the ride height often. Less is more. Quote Link to comment
ggzilla Posted July 2, 2011 Report Share Posted July 2, 2011 Don't forget the number of coils per inch. after you figure out how many inches the spring will compress accorinding to the distance from the ... thing. Which nobody seems to know. Best thing to do is call a spring company. For a couple hundred bucks, they'll sell you the right lowering springs. Quote Link to comment
Creepy Cruiser Posted July 2, 2011 Report Share Posted July 2, 2011 The biggest mistake I see is: People when doing this, just cut one side and set it down and look at it. Then they decide it's not low enough yet, so they cut the same side some more. When they get that side where they like it, they go to the other side and cut it to match, and now the cross member is sitting on the ground, lol (now they have to buy new springs). Keep in mind the other spring will hold up the car, so like Mike said, go slow, and do both sides at the same time before you set it down to check it. Also keep in mind it will settle after you drive it, so leave it a little higher than you really want it at first, (you can always go back and cut more). Quote Link to comment
510 Bomber Posted July 2, 2011 Author Report Share Posted July 2, 2011 thank u everyone. im gonna cut one coil. and its coils all around. and later on, ill get stifer shocks. but now i just want it low. so i think one will be fine. i will post pics, hopefully i do it tommrw. :))) Quote Link to comment
808DA6 Posted July 4, 2011 Report Share Posted July 4, 2011 Don't forget the other factors in being low. Camber plates and bumpsteer spacers are going to come in to play unless you want to wander all over the road. Its pretty scary. -B 1 Quote Link to comment
I'm BLUE Posted July 5, 2011 Report Share Posted July 5, 2011 At least build a jig to measure before/after ,,,, even out of wood !? :unsure: Or save your-self a headache ,,, do a little search ,,, and see what your after-market options are on lowering springs/struts :D Good luck :) Quote Link to comment
bananahamuck Posted July 5, 2011 Report Share Posted July 5, 2011 I would like to add,, do this with a full tank of gas and anything your going to be carrying in the truck .ie spare tire, jack . Quote Link to comment
Stupid_fast Posted July 5, 2011 Report Share Posted July 5, 2011 On my toyota I cut one coil all around, replaced all the shocks too. Rides ok, handles better than stock too! Its all about moderation, cutting springs for about 1" drop depending on the car should be fine, but the more you go the shittier it gets usually. IMO a small cut for stance/lower center of gravity is fine. And take into a account, the more weight, the more lowar it will go. I drove up to Canada a few months ago with it lowered, with all the luggage and my bro in the back it was about 1" lower than it is empty. There was almost no wheel gap. Still rode fine for 1800-or so miles of freeway. Quote Link to comment
Laecaon Posted July 6, 2011 Report Share Posted July 6, 2011 Cutting springs increases spring rate. Your shocks are only rated for so much spring rate. Cutting to much will make your car more bouncy. To think of it another way: As you wear out your shocks by normal driving you notice over time the car gets bouncy-er, my friends buick was a great example of this. So just be weary and dont cut too much. Quote Link to comment
Wide14u Posted July 7, 2011 Report Share Posted July 7, 2011 so have you cut your coils Quote Link to comment

Mr.Dean_Yates Posted July 7, 2011 Report Share Posted July 7, 2011 well i chopped my 240 springs took off about 3 coils? take a look with the old rims (possibly for sale btw) and just because i really like this pic lol Quote Link to comment
Mr.Dean_Yates Posted July 7, 2011 Report Share Posted July 7, 2011 sorry i dont have any before pics but if i find some ill edit the post Quote Link to comment
ggzilla Posted July 7, 2011 Report Share Posted July 7, 2011 Looks good. How does it ride, how much suspension travel do you have left? Quote Link to comment
510 Bomber Posted July 7, 2011 Author Report Share Posted July 7, 2011 i have not lowered it yet. just wanted to get ideas. still on the body work. i will post pics of the progress Quote Link to comment
Mr.Dean_Yates Posted July 8, 2011 Report Share Posted July 8, 2011 Looks good. How does it ride, how much suspension travel do you have left? rides smooth actually. im very happy with it. after i get the front airdam im droppin it another inch or so. as far as travel goes? i dont touch tires to body and ive taken it thru some tight hairpins. but im very happy with it.

Mr.Dean_Yates Posted July 8, 2011 Report Share Posted July 8, 2011 i have not lowered it yet. just wanted to get ideas. still on the body work. i will post pics of the progress do you know how to align the springs befor you cut them? if not ill grab some stock springs and show you thru the forum :D 1 Quote Link to comment
510 Bomber Posted July 10, 2011 Author Report Share Posted July 10, 2011 align? i was just gonna hop up on the coil, and cut right above the origanal stoping point of the coil made a shitty drawing on paint, but hope u get the picture coil Quote Link to comment
Spades Posted July 10, 2011 Report Share Posted July 10, 2011 Yeah, I never recommend doing this, but if you have no money and are trying to get a higher spring rate and lower suspension, well, do it carefully. I am guessing with one coil you should see a 1 or 2 inch drop. I would not take any more off to start, and try to use a low heat cutting method and stop every so often to let the spring cool, you do not want to heat it up. You will most likely need an alignment after this to fix the negative camber(unless you are one of the people that thinks that looks cool and wants to run through tires quickly), and it may help or hurt handling depending on how you cut the springs and all sorts of other variables. Just be careful, take your time, and cut both springs at the same time...if you have to remove it all and chop more off, it is easier and cheaper to have to pull the struts out again than it is to try to put spring material back on. NOTE: keep in mind the car may "settle" a little after re-installation, you may want to drive it a few miles after chopping the springs to see what the ride height will be...it may not be its final ride height right after installation.

510 Bomber Posted July 10, 2011 Author Report Share Posted July 10, 2011 im goin to take the springs out and cut them. ive got the tool to compress springs and my bros shop 1 Quote Link to comment
Wide14u Posted July 11, 2011 Report Share Posted July 11, 2011 i want to see so go do it :D Quote Link to comment
