Cut OE Springs
 

Being they're linear and there isn't any progression to change; has anyone successfully anyone cut their OE springs rather than using Swift etc?

On another platform I owned with linear springs it was a very common modification without any repercussions. We were typically dropping 3/4" to 1-1/2" without any harm to even the OE shocks and struts.

I'm surprised I don't see it at all in the Z community.

Who refers to previous cars they’ve owned as “another platform I owned”? Don’t be shy. Tell us about your old car with the 1-½” drop on cut springs. We won’t hate.

I do and it's inconsequential to why I don't see it on Z's. If you're only here to :stirthepot: see yourself out.

"On another platform I owned with linear springs it was a very common modification without any repercussions."

Yes, it matters because you were the one who used that statement as the basis for wondering why you don't see it in the Z community. It was fine on car 'A', why dont owners of car 'B' do the same?

And you must admit, at some point the question is rhetorical. For example, if I said "When I had a Yugo, we all cut our springs, why dont Zonda owners do this?" The answer would simply be. "Because it's a Zonda, not a Yugo". The answer here could be the same. I dont know. :)

You know a car is getting old when people start asking these questions.

... and cheap

Do things the right way or don't do them at all. If you can't afford a set of lowering springs you shouldn't be lowering your car regardless of model.

If I was looking for a .25"-.50'' drop i would think nothing of cutting stock springs. Just don't tell anyone.;)

I would buy a $4,000 set of true coilovers. When I roll up to the grocery store people will be like "oh ****, that drop is so precise and tasteful, have my babies". I won't, but I could, and that's the goal.

I have done it before and I prefer not too. You can have some issues. It does come at a consequence. When you cut a spring, the spring rates do go up. Test it. If you can't afford springs then no way in hell are you going to buy what is needed to get the alignment back to spec.

I think you meant the rates do not go up, only reduces the amount of stroke before coil bind. You haven’t changed the rate which is the issue, constantly hitting the bump stops sucks.

Have you ever tested a spring after you cut it?

I understand why you'd think this, but it's incorrect. You're thinking about rigidity of the material. The number of active coils (and in a linear spring, they're almost all active) is considered for spring rate. Remember, spirals are basically a ramp. Cut the spring, and you're shortening the ramp.

Ah yea that makes sense. I knew fewer coils is stiffer but I thought it had to be fewer coils over the same distance to be stiffer since then your actually changing the pitch of the ramp
