what about longevity? like through regular usage, how long can I expect them to last?

the point is if they can last 2 or 3 years they it would be probably more price efficient getting coilovers since there's no guarantee that AGX can last w/ rs*r race springs.

i've never heard of a bad tein experience so far, other than some corrosion after 2 years on the steel-bodied dampers....

trust me, spend a little bit and get some nice TEINs or something if you are going to be that agressive, at least you'll be riding on a setup built to take it.-chet

i actually would think that it would be easier to install coilovers, then shocks and springs. u would need a spring compressor and crap, while the coilover is practically bolt on, practically

hehee yea plus I need new upper mounts too... hmm correct me if I'm wrong, but isn't Tein HE discontinued?? which means couple of years down the line it would be hard to find replacement shocks?

if its discontinued, TEIN sure is shipping a lot of them to vendors, phase-2 has them, as does many other places(after-dark has a set)..

i think the real question is how spirited of a driver is he? also, how long do agx's usually last? but if i ask that question, the next thing out my mouth is how long do the konis last? if koni seems to claim that there is no issue with matching those springs to it, maybe u should look into konis. yes they are a bit more but if you dont want to spend the extra couple hundred on coilovers, u could put an extra hundred to gettin konis. of course like previously stated, ur in the tein basic price range. its gonna b ur call but it all depends on how hard u plan on driving the car and how often.

just an FYI, Koni SA's have a lifetime guarantee. If they ever wear out you just ship them back to koni North America and they rebuild them.

Koni has an excellent reputation and are heavily involved in all sorts of motor sports. I've never really heard anything bad about the Koni Sport shocks.

There are, however, two catches...

1) The installation of the front shocks isn't exactly a bolt-on affair. You need to modify your old OE shocks in order to use the Koni's since they're inserts.

2) The rear shocks aren't adjustable while on the car. You actually have to take them off the car to adjust them. This is done by compressing and turning the piston.

They're rebound but not bump adjustable, if that matters to you. For what it's worth, Koni's customer service is quite good.

ok well here's another question. i looked up the rsr springs and they do have two versions. the race version features the 5 and 4 kgmm spring rates while their down sus springs feature a 2.6 and 2.7 kgmm spring rate. if the race ones would b more suited to the konis, woult the down sus be more suited to the agxs? and yes point taken by badmojo. the konis are harder to install than the agxs and the adjustability isnt as convenient as the kybs

The Koni's are very good overall but for street use (no auto X or racing) the AGX is the better setup. Ease of adjustability being one of the stronger points. If you have a track prep car and know where you want to set them and don't use the car for other things the Koni would be a better setup. It all depends on how the car is being used.

hey, how bout some of you ppl w/ GCs paired w/ AGX give us some insight on how the AGX are holding up. I believe the 8kg/6kg GC are popular with AGXs.... how are they holding up?

I actually have the RS*R race spring/AGX combo on my S13. I think they are a good spring for a really agressive street/auto X drivers. If your car is a daily driver than I would recomend theese springs to you. If it is not a daily driver than you probably would want a stiffer spring. Although theese springs are stiff enough to make driving rather uncomfortable. body roll is not noticable until you drive through some slaloms at 50+ miles an hour, and I have stock sway bars. I have actually pushed down on some S13's with tein ha's to see how stiff they are, and my setup is definetly stiffer. All in all I think that this setup is just about perfect for my situation.

no doubt they are stiff, so far they are the stiffest i've found outside of coilvoers... but how long have you had the AGXs.... ? I reallly wanna know if they'll last w/ such stiff springs w/ some crazy driving

I have had the KYB's on my car for 4 months, and they have been wrapped with RS*R race springs for 1 month. I have the dampers set at 4 & 8, at all times. I'am thinking about adjusting them. There is hardly any roll up front, but unfortunetly the rear does roll. So I think setting the front at lower rates should make the car a little more nutreul. I will eventually buy adjustable sway bars, that should help me dial in my car enough to satisfy my auto-Xing needs.

The stiffest spring that you can get outside of coilovers would have to be KG/mm's (from what I've read about them) (it is nearly impossible to buy them in the states though. if anyone is thinking about getting some tein's you should probably get them custom spected. Have them give you stiffer springs, and they will tune the dampers to the springs for optimium perfomance. It will cost extra money and take longer to get them, but well worth the extra $$$. I have heard of to many unsatisfied "ha" owners.

my main concern is if the AGXs will last under such stiff springs...even hough the teins are more expensive, if the AGXs wear out and you need to get another set, then that would be enough to make the difference.

I paid 250 w/shipping for the RS*R RACE SPRINGS, & 440 for the kyb's. If you look around you can get the KYB's for 360. It is honestly a very potent combo. (for street/track use) any stiffer of a spring and daily driving would be rather uncomfortable. I still have a bit of under steer, but I think I'am only a couple of sway bars away from tuning my car to handle nutruel. although, I still haven't messed with my tire pressure's, damper levels, & front camber/alignment. By the way, so far my suspension setup consists of; tein front upper adjustable strut pillow mounts, whiteline front lower control arm bushings, whiteline TC bushings, new moog ball joints/tie rod ends, battle version adjustable rear toe rods, custom rear strut bar, (the home depot version), KYB AGX's, & RS*R race springs. I have mainly been replacing suspension components that are worn out. next on my list are; front strut bar, front and rear sway bar, & 3 degrees of negative camber up front. (some new tires are also on my list). I will post up and let eveyone know how my car performs on the track. I have not autocrossed since I got my RS*R's, but I'am confident that they will improve my times.

are the RS*R RACE springs lower than the Eibach PROKIT?

i currently have the AGX & PROKIT combo, on 3/7 setting ti is a pretty *decent* street/autocross setup...

but i am looking for something a bit lower for now,

i have heard that the EIBACH sportlines are lower but have lower springrates and cause AGX's to bottom out..

from reading i guess that the RS*R are great springs when combined with the AGX's, but are they lower??? and what are the spring rates?

i am looking for a cheap alternative untill i can afford some JIC, TIEN or CUSCO coilovers next year.

untill then, i want lower springs w/ stiffer spring rates and i'm getting the pdm special without the whiteline springs, (whiteline swaybars, bushings etc)

my car is almost nutreul handling with just a tad bit of understeer in certain situations. I have 1.8 degrees of negative camber in the rear and 1.3 negative in the front. Eventualy I will have 3 degrees of negative camber in the front. That should help it hook up some more. the 1.8 in the back is from lowering the car. I think that the RS*R race springs lower the 240 just as much as the pro kits, but in my opinion not low enough. All though, I bottom out all the time with my OE front lip. I do believe that the spring rates are listed early in this thread. I dont think that theese springs are stiff enough to blow out kyb AGX's that easily. people use stiffer rates on there ground controll coilovers with kyb's all of the time,and In my opinion the best bang for your buck would have to be the ground control/kyb combo w/ an 8/6 kg/mm spring ratio. the RS*R's are only a 5/4 ratio and do not lower the car as much, but are the only other real "performance spring" out there. In my opinion, All others are just a lowering spring.(unless you can get a hold of some kg/mm's, and if you can e-mail me with there web site, they make they stiffest lowering spring around, hands down) And like I said in an earlier post, the RS*R's offer the best comprimise between ride quality and performance, I think the 240 should of come stock with the RS*R ride hieght/spring ratio.
