i dont understand u people.. it done my car great, maybe im just not use to a "good" handling car but it definatley handles better than stock. btw who gives a **** about handling i just like going from 25-150 really fast in a straight line i didnt buy them for performance just an apperance mod.. u cant argue aginst it makin the car look ten times better

sportlines have the same front rates as the stock 1LE springs, and actually softer rears. pick up a set of those and hack em off 2" and you have essentially the same thing. doesn't take a genius to figure out why that isn't going to be great for handling.
to the OP, the springs look great. for your use, they are fine. i'm only continuing to share my dislike and reasoning for it for those arguing that they are good springs for handling and not just an appearance mod.

The springs looks great, but they are absolute **** as far as working suspension. Just read some stickies and facts on suspension and its easy to see.

Not to start trouble but you have to define "good".
In the sense of a good handling spring, no, they are terrible, arguably the worst. Get under the back of your car and check how much suspension travel you have. This is a picture of the travel with the prokit which is higher than the sportline springs:
You are left with almost no suspension travel and combine that with really soft spring rates and you are on the bump stops 99.9% of the time you are driving. This is why the sportline springs are hated, they are way too low and don't have near enough spring rate to compensate.

You said thats with the prokit?
So pretty much any lowering spring will kill travel in the rear, how do you compensate, outside of incresed rates?
Looks to me like there is less than an inch there (on a mild drop like the pro kit) so pretty much no currently available spring will keep you off the stops.
So what do you do, step up to a shorter but stiffer stop?
I think Shon sells some polyurethan ones, that look like you could trim a puck of them, would that help?

And a higher rear spring rate and/or rear springs with less drop.
Also the only poly bumps I would try are the E.S. jeep bump stops(#9.9137).
These will give you a little over 1/2" more suspension travel, but when you hit the bumpstops,you'll know it. Since they're noticeably stiffer than the factory bump stops.

and for all yall yeah sportline is prob not the best out there, hell it might be the worst, but like i said it was just an apperance mod and as far as apperance i think i reacehed my goals, now for performance i know its not that great im not arguing that and according to yall im up a **** creek with these springs

Sorry but from that pic I highly doubt a good shock is going to keep you off the stops much.
Think about it thats a prokit, on of the mildest drops, and theyve got about a 1/4 to a 1/2 of travel, youd have to go crazy on the spring rates and compression dampening to keep you off the bumps, at least on the roads out here, and at that point is it really an optimal setup anymore? Doubt it
Im willing to bet if that seriously is a prokit, and not sportlines, that every other lowering spring is just as bad, so at that point is it even an issue.
I mean is hitting the bump stops that horrible anyway, arent they just a suspension travel limiter.
As Ive been taught, they work like a progressive rate spring, although the actual spring rates can be linear, when you get on the stops, its working like a stiffer spring, to prevent additional suspension movement.
I dont know if what im trying to say is getting across but to me it seemed liek that pic was used to show an issue (limited susp travel) and it seemed like people where saying its something exclusive to eibach, but in reality at least it seems like it to me, that'd be an issue on every spring.

And that is certainly not a "mild drop", while they are rated at a ~1.3" drop they are often much more than this thanks to spring sag, more like a minimum of 1.5" drop.

And yes this generally is a eibach issue (or any spring with 1.5" or lower drop) because the springs sag, so their claimed drop is not the same as the actual drop. I have WAY more travel than that (although I have the stock shorter WS6/SS bumps stops, but even with the Z28 ones it would still be more).

Hell... This thread has gone to the shiter anyways...
I have BMR springs.. How good/bad are they and what for..
I only care about the drag racing aspect.. But am also curious as to how they match up against others in the corners, just for ***** and giggles!
