I have a s14 and have a set of RSR race springs sitting in the room downstairs. When I bought these I was under the impression they are linear, but turns out they're progressive. Right now I'm havng 2nd thoughts because I have heard progressive springs can be unpredictable (can some explain to me more why?)
My options right now are to:1. keep the RSR, they appear to be high quality and have good reviews2. sell the KYBs and RSR and go for coilovers (FLTA1us from JIC is being sold for around $900 on group buys)3. ground controls - although this really isn't that good of an option since for $400, it puts me in the coilover cost range, and I'm not a big fan of all the work for the GCs to fit.4. another brand of linear springs, know any?
So far the only linear springs I know of besides custom and KG/MMs are tanabe's GF, but Tanabe themselvesev said the springs were designed for the SR motor, and plus the spring rate is a bit low for my taste.
*I know I said I had no regrets finding out these springs were progressive, but for the past 2 weeks while waiting for the stupid KYBs to come in IU've been givin it more thought, so I'll eat my words haha*
progressive springs bad?
but I've heard alot about progressive springs bein very unpredictable on eh track where your car's at the limit, and something going wrong when your car's at the limit doesn't sound like a very good thing. Oh that picture, is not ana ctualy picture of what the S14 springs look like, from that picture that's how I got the idea that these springs are progressive.
no it's not going to be a race only car, but I'd like to have some linear springs.dystopia - what kinda car does your friend have?
The story is, I bought these under the impression they are linear, but when I took a look at them once I got em, they looked progressive.On the rear, 1/2 of the coils are close together and the bottom half is farther apart.On the front, there's only a total of 4 or 5 coils, and they get farther apart.
from the looks, they're progressive, so I called RSR USA and they told me they are progressive. But then again, their representative might be wrong. And I've heard about linear springs looking progressive (like the kg/mm linear springs) as they have "dead coils" which have no effect once the springs are situated on the car.

ok, look. your siteing the fact that progressive springs are "not optimal" on a race track as the reason that you dont want them.
progressive springs are specifically designed to be more comfortable on the street while your not pushing the car.
a linear spring will be very stiff [provided they have a high spring rate] all the time.
have you ever driven a car with progressive springs? its not unpredictable. your not driving on a track. your probably never gonna take the car on a track anyway. your not competeing for 1/10 of a second. you have to drive this car around on a regular basis. ever think of that?
"something going wrong at the limit doesnt sound like a good thing"
you probably woudnt be able to tell the difference between the springs anyway. can you take a car around a corner at the limit of adhesion and not smack into a telephone pole or run over any pedestrians anyway?

quote taken as good advice
for a street car, your better off with a progressive spring rather than a linear.
over small bumps and road irregularities, a progressive spring will absorb the roughness better. also when you corner, and load the suspension, the spring increases its rate, supporting the car better.
granted, a linear spring will be slightly better at "full tilt handling", its gonna be stiff and harsh constantly.
on the street, you dont drive your car at 100% all the time.
