yup saw my buddies lastnight half of the springs are all touching

 

Yea they have three touching coils at the top, it doesn't hurt the ride quality though. I recommend them to everyone. If you want ugly coil bind go with the sportlines lol.

 

All lowering springs bind. Unless paired with proper struts for their rates but under heavy load they can bind

 

Haha mine are like the pic but a little less.. but mine have the black plastic on but they are binding lol

 

dang I've already bought eibach lol.. I heard from powell that they do but didn't think they were that bad but then saw a few posts about them. are the pro kit springs as bad? there's no drop in the front and only half an inch in the back with the pro kit on an SS TC

 

i have sportlines the rears coli bind have to get my pedders installed ASAP. they are sitting in my living room

 

Mine have been on the car for somethin like 5 years but here's what you get after all that time. I know there are unsprung dead coils but this is ridiculous... Coilovers comin' soon

 

I have ProKit springs and they aren't as bad as demonstrated.

ProKit springs have some of the 'softer' parts of the spring covered in rubber so they can stackup and bind under heavy load (like hard cornering) and allow the stiffer part of the spring to work as designed. In some cases, for progressive springs, coil-bind is the norm -- it's designed to work that way...

My sportlines have this rubber on them as well

 

oh okay

 

u r a smart guy and a good racer Scott I cant believe you are saying this. coil bind springs are crap.

 

one working coil. u are right, redonkulous.

 

I would postulate that if those coils always stay bound, it's not so bad. However, if they unbind and bind during driving, the spring rate will be inconsistent as it transitions. Is there any load on the car in this pic? That looks excessive, but the fact that they have the sleeves all the way down there is not a good sign.

 

Powell, are you working on a set of springs for the Cobalt?

 

**** coil bind.

Megan Springs:



Btw should i flip these upside down? ive seen people mount the springs both ways.

 

ive always seen them mounted opposite, with the most coils on top.

 

I'm pretty sure the coil bind should be on top.

 

Granted. I simply point out that allowing coil bind is one way of configuring springs to have both soft and hard sections (the softer section compresses and eventually binds and that forces the stiffer section to do its job).

I'm not advocating coil bind. But it is a fact of life for some springs, and anyone who buys those springs should expect coil bind to exist... Some springs are worse than others. The springs pictured are horrendous!

Scott

 

shouldn't they bind only under load? I could be wrong but how I understand it is that if they are always binding even with the car sitting then you always get the stiffer section

 

You want a little bind while sitting to keep them seated in case you completely unload the suspension so the spring won't fall out. Just not 3/4 of them while its just sitting.

 

'If' the springs are designed to bind, then, as you say, they would only bind under load (perhaps heavy load would be a better description). They shouldn't bind under 'normal' load conditions -- like just sitting there.

Obviously, some vendors (apparently) deal with 'drop' by weakening the springs and thereby causing excessive (early) bind. I can't prove any of this, it's just my suspicion based on what I'm seeing (the photos).

I might also add that 'cheaply' built, improperly heat treated springs, might quickly 'sack' (I'm not sure about the spelling) -- in other words, the metal weakens quickly with usage and loses its initial strength, thereby collapsing upon itself.

It's also worth noting that springs that coil bind regularly will frequently 'grow' larger in diameter as a result of binding (they are kind of squished out).

Regardless, the end result is what is seen in the photos.

do you guys think that having the springs in the rear upside down is affecting anything? My rear seems super soft compared to the front, even with the rear bind. the front bind is HIDEOUS.

I need to cut my front bump stops! (how much should i?)

 

If you want an opinion, I'd suggest getting another set of springs. There's no way your car can handle reasonably with that much coil bind (did you get them used from somebody else?). Yes, you should turn them over...

Scott

 

Your bump stop is there for a reason. It's keeping you from paying big bucks fixing broken **** due to crap coils. Don't cut it. It's far better to pay for better springs than it is to pay for repairs and then pay for better springs.

 

they are megan springs with about 50k miles on them.
