Thinking of cutting one coil...

All of the pics of the H&R sports I have seen on 135's have a huge rake. All of the rear are a decent ammount higher than the front. I have a set of H&R sport springs, and I am considering cutting one coil off of the rear only, inorder to even it out. What are your guys thoughts on this? Keep in mind I hear that some aftermarket springs actually work better with a small amount removed.

Call TC Kline and get some adjustable springs. If you look at the H&Rs, you'll see that cutting a coil will make them sit weird in the spring perches, and they would compress differently. Plus cutting a single coil doesn't get you much height difference.

Another thing to think of is that you'd be lowering the car more than an inch, which is usually the threshold for the stock dampers.

This is worse than cutting your stock springs. You can die from this!

if you can afford a BMW, spend the money to mod it correctly. cutting springs is not it.

Cutting spring is usually considered because it is supposedly cheap, but only in up-front costs, 3000 miles later you are replacing suspension components. Cutting a spring causes an unknown increase in spring rate. This may cause unknown (usually poor) results in handling and safety of the vehicle. It also increase the stress level put on the spring as well as adversely effecting other related chassis components. Will tend to blow out your shocks much quicker as, so in the long run, not cheap anyway.

didn't you learn your lesson from back in the day with Honda's and Acura's?

Cutting springs is a BIG BOUNCY MISTAKE!!!

I remember when people would cut, vs melt, and even clamp the springs.

My buddy clamped his springs and the clamps broke off a few days later... the car jumped up like it had hydraulics.

Another buddy decided to just take out the springs... thing rode stiff like a skateboard.

Oh welll that was 15 years ago and we all learned are lessons since then.

Please don't this!!! You're going to ruin your car, there are alternatives! Spend the money and get it done properly. If height is all you're concerned with, I would look into KW Variant 1.

Hmmm. Activeautowerke.com is listed as your homepage, and you list yourself as living in Miami,FL where AA is.... Was this a test? If so... we passed

LOL!!! I remember MANY years back I had a '78 280Z. My friends father raced Z cars and had an old set of race springs laying around. One day we got out the torch and started cutting. Long story short.. yes, it was one of the only slammed cars around at the time. No, it wasn't a good idea.

Well it has nothing to do with money. I asked to cut only one coil off of the rear H&R springs. I asked this because I have heard many times that with progressively wound springs they sometime perform better with one coil cut off. When I recieved my springs and looked at them, they do not seem to be progressively wound. So i am not going to do it. I am going to wait until more aftermarket support becomes avail. Fow now I will just deal with the H&R.
Anyways I just wanted to see your guys thought on it. I am aware of all ofthe affects of changing spring rates and what not.

Damn, clamped springs is a really bad idea. Thank goodness I never have had to go through all of that. Though my friends did, the cars drove like crap.

Well that makes sense. If you will try to put some one down, please use a coherent sentence. By not doing that, it makes you look less educated, and by doing that you might actually get your job accomplised.

Also you do not cut shocks, it is springs. Please read the thread, before you criticize people within it. It is stated very clearly that the subject is springs, and the reasons why it was brought up. And please do not put down civic drivers. There are many people who own civics that are huge automotive enthusiasts, and who make very nice cars. Cars that are very fast, and nice looking. Civics make excellent cars in every aspect, reliable, quick, safe, moddable, very capable in races, etc. And please do not sterotype people, you may offend someone.

I think it would probably give a huge increase in cornering speeds...

Absolutely predictable increase in spring rate with non-progressively wound coils. I have found more consistency cutting coils then using aftermarket coil springs.


k = spring rate constant
G = material rigidity
n = number of coils
D = Diameter of wire

Consider 'G' constant; but, it is really not because you will get a lot more consistency from OEM then you will from some of the after market springs. It probably has to do with the temporing process. It is also easy to calculate your resultant ride height.

It is true that you will need to have your shocks revalved for your new spring rate; but, if you are going to change springs to a stiffer spring, you should have your shocks revalved anyway.

Read any of the ___ to Win series -- Engineer to Win, Tune to Win, Design to Win or Fred Puhn's, How to Make Your Car Handle.

Every H&R, Tokico, or Eibach that I have installed has sagged. Hint: Don't cut your springs with a torch, that will surely create some unusual spring characteristics.
