Cutting Neuspeed sport springs (just a little)

4081 Views 47 Replies 18 Participants Last post by  madtownhonda
I have thought about cutting my Neuspeed sports front springs.
I love the rear look (1 finger gap). But, the front is 2 fingers and just would look much nicer with that same 1 finger gap as the rear.

I would prefer to go the route of cutting the front ones a little, but have thought about the following:

Blow $140 on Neuspeed Race and just use the front
...take the Sports / Bilstein HD's out and get full coilovers

Unfortunately, $$ is tyte now, so coilovers are out of the picture for a long time

Anyone ever done this to an aftermarket spring? I'm talking a 1 finger cut down so that is not much (I don't think). == maybe one coil.

If you aren't concerned with a bumpy ride you could look into R1 coilovers. They run like 125 a set. I believe the spring rates for them are pretty high. Like 450/350 front and rear respectively.

I really don't want to put any more $$ into the suspension right now. That is why I am asking about cutting a coil out.
Go for it then. Just start out small. I would hate to see it be too low. I knew a guy that cut his aftermarket springs. It throws the whole balance of the spring off. It isn't that bad though. Just a little more bumpy.
Cutting your springs

Hey I"m confused...

the front is actually Higher than the Rear?

I thought it's usually the other way around...
when I had neuspeed sports my front was lowe than the rear??
No it is the same way as it was on my car. It lowers it 1.7 front and 1.5 back. The front fender wells are larger than the back so the front can be lower, yet still have more wheel gap.
nooooooo, dont cut your springs. because what happens when you cut your springs is the height of your springs changes but the spring rate doesnt, so sometimes when you go over a bump your coils will run into each other, and thats not good. your ride will be alot bouncier. just save your money until you can afford coilovers.
cutting your springs is the stupidest possible thing you could do short of getting hydros on your honda...wait no, its stupider

haha..no, hydros are cool man. go ask the guys in manassas.
i know cutting lowering any springs is a bad idea especially
lowering springs.
but in my opinion i think its ok if you do it just a lil bit.
i mean anything more than .75 inches is a bad idea.
your ride should not be a lot bouncier since you have
shocks that are high quality.

That's just asking for trouble. First, even if you just cut a little bit off, the suspension problems created from cutting springs are due to the fact that you can't cut the exact same amount off of each spring, and it doesn't take much to mess up the balance of the car like that.
Second when you cut springs you are going to change the molecular structure of the metal of the springs. Molecules realign when that much heat is applied to the metal and the result is something like what happens when steel is tempered...the metal becomes stronger and more brittle. That means that you will not only mess up the balance, you'll mess up the spring rates (so you'll prolly end up with 4 different spring rates basically), and you'll increase the risk of having the extremely bad happen...springs cracking.

This stuff happens no matter how much you cut off 'cause humans are falible and fire is hot...

That is enough!!

My brother said there is a boy who will buy my springs. I told him to tell the guy $100, but he said more like $125. I told him $115 would be fine :) (They are only 3 months old).

Back to researching..... Looking for springs to go with my Bilstein HD's that will provide a 0 or 1 finger gap ALL around!!

well i dont see how he would end up with 4 spring rates when he was gonna cut just the 2 front ones. and if you know what you are doing you can cut the same amount off of each spring.
and with lowering springs several of the top coils touch eachother so i dont see how that would change the molecular design of the spring since those are dead coils and they are not doing anything than keeping the spring from falling out from the perch when going over a big bump.

Do you bottom out anywhere yet or scrape?

Haven't had neither happen.
I didn't realize that he was cutting only the front springs...

You cannot cut the exact same amount off each spring with an oxyacetylene torch. The torch will not give you a clean cut, so they will be a little off. The only way to get a clean cut is to use a plasma cutter...

Also, not all springs have that many dead coils (some only have half of the first coil used to mount to the seat). However, regardless of how many dead coils there are, you are going to be heating the metal past the cut (how far past depends on the metal, the process used to make the spring, the heat of the torch or cutter being used, outside air temperature, etc.). Heat breaks molecular bonds...it's the oldest way humans know to break molecular bonds, and there's no getting around the fact that the bonds will begin breaking. Not only that, but the heat will also expand the metal. When the metal cools, the molecules will rearrange themselves so that they can bond again, but they won't bond to the same molecules as before. This, coupled with the strain that will occur when the metal contracts again when cooling will weaken the metal of the spring. Since this will happen to only some coils, and not evenly, you are going to have unpredictable results. This is pretty much what happens when you take a thin bar of metal and bend it over and over again in the same place...the molecular structure is changed with each bend (bending the metal creates heat), and eventually the metal is weakened enough to just break...

when you cut an active coil, the spring rate gets higher
