I find it very interesting that the Tein H-Tech's have basically the exact same spring rates as the Spec-V stockers.. with a bit of added drop.

It's good to have you back man...I hope things are going well.

I would only make one suggestion. Including a quick reference for susp. novices...on what spring rates are and why diffecences are significant.

This is a FAQ if I've ever seen one.
great suggestion.........maybe a reference on the significance of properly tuned dampers as well??

nice after thoughts

another thing i think you should add in there is the fact that the JICs actually provide you with OVER 2" of suspension travel in the rear.......which is a) more travel than the stock dampers and b) the only suspension available with that feature

also........you should mention something about the JICs being able to preload the springs independant of the ride height......which is another reason why they cost that much more than a set of Tein SS

Thanks. A lot of what you're suggesting I cover in my b15 suspension writeup on Southern_Shift, of which a link is provided in the post. I really don't want to dwell on one particular product more than another, and my writeup on S_S goes more into the advantages of one over the other. Read into it, I think you'll like what I have to say about your JICs.

lol........i'll check it out............i wasn't actually saying those things just b/c i own JICs lol..........it was more of a suggestion as to the different types of suspensions available.......most people don't realize what spring preloading can do for you if you set it up properly (you can effectively double your spring rates just from preloading them )

i haven't read the write up on southern shift yet (will in a couple of minutes) but you may want to address the differences b/t inverted monotube dampers and non inverted twin tube dampers.......i know for a fact that the majority of people definitely don't understand that one

Late,
Daniel

This is awesome, thank you! I'm also curious why the Tein spring rates are essentially the same as stock. Interesting. The Progress springs are also softer in the rear than stock, which is another anamoly to me, but I'm no engineer.

Great post!

Makes me want to switch from my Progress/Koni setup to a Tanabe GF210/Koni setup

I thought the Progress were the stiffest we could get as far as springs are concerned. I'll definitely look into the GF210's pretty soon.

Talking

i have the sportlines springs, is that a good springs, and i think its good handling except for bumps. the rear makes that squeky sound when it was installed a while back, is that because of the struts or just the upper mounts. so other coils dont have upper mounts iincluded just ksport and jic do. Im thinking of getting the konis but then again im leanin to get the full coils but dont really like to higher or lower the car.

You probably have the gen1 sportlines, the rates on those are like 150F/190R with a drop of 1.5"F/1.4"R, so it's not surprising that things get a little rough over bumps.

Usually that is the rubber wearing away from the top of the upper mounts so the squeaky sound is metal on metal rubbing. Nothing one layer of duct tape can't fix.

Damn fine thread Stephen

Daniel, if you would shed the light on preloading some GC springs so I can get 1000 ft/lbs, I'd be surprised...

lol.........i never said i knew the exact steps needed to take in order to effectively double the rates.......i just know that after talking with numerous racing teams at events i've attended as well as guys who work for the suspension companies i've been told across the board that if you preload the springs the right amount it will effectively double the rates

i'm sure that there is an equation or process though somewhere out there on how to figure this out
