herad good things about the coilovers but no idea on the springs alone. Honestly, i'd get a set of koni's w/ coilover sleeves or full coilovers if you can afford to save up the cash, the handling is dramatically better and the ride can be fine tuned to be quite smooth and liveable.

Biggest thing you want to make sure you get with drop springs if you do decide to go that route, you want LINEAR rate springs, not Progressive rate. Progressive rate springs will beat the hell out of the struts regardless of what they are, kyb, koni, arvin, stock etc. Linear springs are much smoother in compression as they dont have dead coils in em. Progressive springs can be identified by a number of dead coils that bind when installed(coils touching with the weight of the car on em) where as linear springs(same type as stock) will not be bound except for the ends of the spring touching the first coil.

Progressive springs are exactly what it sounds like, more load=more tension meaning no preload on the springs. This induces bounce, and a lack of control of the car.

Linear springs will be preloaded from the start, and will not give the bounciness or harshness, due to that preload. The springs dont need to hit a certain amount of compression before they react, they will increase the rate in a linear fashion instead of snapping back if that makes sense...know what i'm trying to say, cant articulate it into words lol.

HELP lol

I just threw on my KSport full COs and I like them. They make some noise while turning because of the pillow ball mount but other than that 36 way dampening with spring preload and ride height settings....They rock out loud.

I'm quoting you above, but they are progressive. Mopar springs are linear.

Apart from the aformentioned Mopar ones, are there any other linear springs available ?

From what I understand a lot of the springs on coil overs are linear. Not 100% sure though. And I'm referring to true coil overs, not the eBay ones.

Which means you have to invest at least 1k to get a good setup.

Pretty sure that is backwards.

Eibach Pro Kit: Progressive
Eibach Sportline: Linear

I think i remember hearing the H&Rs were linear, and of course the high rates are, but aside from that are there even any other linear springs available for 1st gens?

Virtually all coilover springs are linear, full coilovers or sleeves. The only time I have seen "progressive" coilovers, they were setup with a second, smaller spring of a different rate stacked below the main spring with a collar between them.

Another thing about progressive rate springs is that they have a different effective spring rate throughout their travel, so thus your suspension will be stiffer or looser depending on where in its travel each corner is causing forther unpredictability in your handling.

Also sleeves are not entirely bad, as long as they are of good quality and attached to a quality strut (Koni) they can be used with success. Many 1st gen Neon auto-x winners have used Ground Control sleeves on shortened, revalved Konis.

Both Eibach kits are progressive design.

Look here:

Pro-Kit
http://www.ajusa.com/details/index/252/ ... %20L4%20FI

Scroll down and you will see.

From everything I remember the Mopar springs were the only linear springs available without going to coil overs. You are correct when you speak of the unpredictability of progressive rates since the spring rate varies progressively as the spring compresses hence the progressive name for it's design.

Im not sure what mopar springs are being talked about but the part number for the high rate mopar springs is P5007003 for the front, they are 225#/in and 1" lower, P5007005 is the rear, they are 185#/in and are also 1" lower.
