I have a chance to get either Hyperco Gen II's used, or a new set of Road Magnet Gen II's (updated drop height).
WHat one should I get?
I have AGX/GC right now. 375# front and 300# rear

I'm sorry I didn't copy everyone else's setup. If you need a preacher to tell you what mods to put on your car, the Reverend Veilside180sx might have a suggestion.
so does a progressive spring rate mean the harder i dig into a turn the stiffer it gets? I'm looking into one of these two as well and just trying to figure out which one i want. I plan on auto-crossing and DD. I also live in Orlando where pot holes are part of every day life.
Yes, progressive rate springs do get harder as they compress.
I also DD/AutoX, and live on a NASTY dirt road! My current setup makes even little imperfections feel like potholes. I know how you feel!
I was asking basically for an opinion. I got it, and I bought the Road Magnets. Dont really like the idea of progressive rate springs... I heard that they can create an unpredictable car with literally a different rate at each wheel!
Whether or not thats an issue in real daily life i dont know, but...whatever! :^)

Don't worry about that too much. That isn't as big an issue as you might think.
Even with a progressive rate spring, the relationship between the amount of absolute force you apply to the spring and how much it compresses is consistent. That is, if it takes a force of 100 lbf to compress a progressive rate spring (of decent manufacture) from rest 1 in, it will always take 100 lbf to compress that spring 1 in from rest.
What this means is that a progressive rate spring will be perfectly predictable. Since drivers percieve lateral force from a relatively fixed reference point, a car equipped with progressive rate springs will be no less predictable than one with similar linear rate springs (as long as you have the same springs on the left and right side of the car).
Progressive rate springs are a great tool for maintaining both ride comfort and suspension travel. If you can swallow the design costs, there really is nothing wrong with using progressive rate springs.

Thank you very much for your insight and knowledge.
I knew that there is no problems with progressive rate springs. The damn things come from Hypercoil who primarily designs springs for the top race teams world-wide and a half dozen heavy-league after-market tuners. Further, Mike K (Chriscar, etc..) from our Forum had a hand in designing the Hyperco springs. Does anyone honestly think that those dudes combined with the Hypercoil Engineers did not know what they are doing? C'mon now....
However, I did not know "WHY" because I am ignorant as hell.

Don't be too hard on him. I remember saying the exact same thing on another forum a few years ago.
That and experts can and do screw up. It's good to check their work every so often.

^How are you liking the RM's? I'm looking to either get them or the Gen2 Hyperco springs for my daily driver..........They seem to be the reverse of each other from reading in this thread.
No spring actually has the compression ratio to 100lbs per inch every inch on the spring if its a 100lb spring. Which is how the spring rate is determined as most of you know. But Hypercoils have the closest percentage to actually having that ratio 50/50, but they are still not . Just a little tip I thought I throw out to you.

My Road Magnets arrived ten minutes ago. I'm excited to get them on. They will be paired with AGXs. Just gotta order some Koni "foamies" and some new boots, then I'll be set.
Hey Shawn, you could use these pics for the suspension thread if you want. I don't recall seeing any pics of RMs by themselves.

Thank you. I shall take you up on your offer.
You know what is the coolest thing about this thread?
It is a question between the two SR20Forum Exclusive Springs. Two intelligent, educated choices.
