AGX and some Racing springs
 
HI there,

there a bunch of threads about springs and struts, but i have some special needs.

I dont want to lower my car too much, and want to make it trackable.

first.. i dont have the money for some nice coilovers, so i want to try it with KYB AGX (already bought) and some nice springs.

i was up on buying tanabe GF210, but now im not sure.. read about the stiffer RS*R and thought about buying these.. are they still available?!

i want to drive my car daily, but make it ready for the Nurburgring Nordschleife, so a stiffer setup should be nice.

Do the RS*R Race drop my car to much?? am i going to kill the AGX with them?

comments from experianced people would be appreciated.

thanks

I'm running Racing Beat springs with my AGX's and I like how my car handles. Not too stiff for the street and they didn't lower it too much. Not sure if you have looked into those yet.

RS*R has been hard to get from what I understand. ARD might be able to get them. I wanted them for mine but couldn't get them so went with Tanabe and AGX. Drop (or rise) is dependant on how old the old suspension is. Mine dropped an inch all the way around. You won't kill the shocks. I autcross, HPDE and other things with my car, don't daily drive it but drive it enough.
With either spring the ride will be fine as long as you take time to adjust the shocks as needed, or as some people leave them as you like. While you're at it might as well replace the bushings, get a rear camber adjuster and some decent tires.

i have the kyb agx's with the racing beat springs and its amazing for track work. plus the kyb's can be adjusted so when your not rcing you can have a half way decent ride.

charge 01-18-07 06:36 PM

on www.rx7store.net they only got the RS*R Downs. Looking bad to get some RS*R Race huh? :(
anyway, is there something stiffer than Tanabe?

adjusting rod in the back, and camber plates in front are a MUST.
racing beat seems to be to soft as i look at the spring rates..

RotorHead87 01-18-07 06:37 PM

I'm running AGX with suspension specialist springs. They use those springs on the circle track.

charge 01-18-07 06:40 PM

what is the spring rate of those?

Shainiac 01-18-07 07:09 PM

From what Ive read, the RBs are about second stiffest to the RSR Races. More importantly, they are also linear rates. This mean the springs are the same stiffness through out the entire range of compresstion. Springs like Eibach, Tanabe, and ST(I tihnk) are progressive rates. So even if they have a stiffer spring rate, the first inch or two of compression will most likely be much softer for a better ride on the street. My Racing Beat spring just arrived today so I will say how I like them.

i was wondering today how these are...dont see too many people with them, take pix if u can. what shocks u using?

charge 01-18-07 07:24 PM

thats interesting..i read many times that racing-beat is not as stiff as the tanabe

Turbo II 01-18-07 07:42 PM

Tanabe is the next stiffest to RS*R from what I understand and they are linear if you get the GF210 model.

Tmato 01-18-07 07:49 PM

I'm using RS-R Races, I fully recommend it. I"ve tried GF210s, they really aren't that stiff. I have actually not tried Racing Beat though, I can't comment on that, but if you can get your hands on RSR race springs, I say go for it. AGXs should handle them just fine (I'm using other shocks). As for the drop, it's a decent drop, not overkill and not a small drop either.

Mindspin311 01-18-07 07:59 PM

I emailed RSR last week about the Race springs. They said they are currently out of stock all over the place but they have not been discontinued as many thought. They said to get back with them in like 2 months and see where they are at.

Mindspin311 01-18-07 08:00 PM

Also, if you can get all the dimensions of the RSRs, you can call up Ground Control and get a custom set from them. Thats probably what Ill be doing.

RotorHead87 01-18-07 08:28 PM

They have a major selection of spring diameters and stiffness. Here checkout the site http://www.bluecoilspring.com/ also they aren't price skyhigh. With my AGX's I went with the 2.5 diameter, 7 inch long springs. I can't recall the stiffness I went because I bought them awhile ago. Good Luck with the 7!!

Here's a picture of my custom coilover set using the AGX/ Suspension Spring Specialist: sorry about the crappy pic but you get the idea

I love my RSR "race" springs and AGX's... The AGX's are really, really nice low-cost struts, with very easy and noticable adjustment settings. The RSR's are great on the street, and paired with the KYB's can be either very, very stiff or very comfortable for daily-driving. I've been commuting a lot (60 miles a day) and daily-drive my TII. I love 'em.

I used kyb agx before.
Very easy/noticeable change and adj.
Just use good springs.

Healing 01-18-07 11:35 PM

Does anyone have any experience with comparing the AGX/RSR combo with a coilover setup (in terms of stiffness, handling and driveability) ? Just curious...

Sgt. Pepper 01-18-07 11:52 PM

I'm running KYB AGX and Tanabe GF210. From my understand GF210s are the next stiffest springs after RSR, and RB are behind both of them.
I like my setup, drop is nice, not overly stiff and it handles nice when I autoX it.

Here is a comparison shot, my car with Tanabe GF210 is at the bottom, the top is RSR springs *sorry forgot whose car it was.* Both cars on 15" vert wheels. I was at a bit of an incline and their is a shadow above my front tire so it makes it look like the front sits higher than it really does.

thanks for the AGX/RSR post with pictures! now i have a clue how far my car will be dropped. but im running the stock 16 S5 rims, with 225/50 in front and back
how much will the RS*R Race drop my car? i have an AERO lip in the front, would be bad to remove it bc the car is to low :D

Stock aero lip? Take a look at eriks car up there, he's got a lip and plenty of clearance. Good luck find the RS*R's, I've been searching for a while now. Everyone including ARD is out of em.

charge 01-19-07 06:44 AM

yea but erik has 18" rims :/

fastrotaries 01-19-07 06:58 AM

who has the racing beat springs AND sway bars

I still think you will be fine. Just be conscious of where you are and what you are doing. I have the MS lip on my S5 TII with stock susp., wheels, and stock size tires and rubbed the lip the other day on a curb because I pulled to far forward.

Turbo II 01-19-07 09:12 AM

^ditto

I have the stock lip and have to watch for everything or it will scrape if I'm not carefull. Sometimes even the underside or the cans on my GReddy PE exhaust will scrape.

now i am sure to get the RS*R Race springs with my AGX.. but how far will it drop the car? the tanabe are going 1.5inch in the front. i read the RS*R Race do not drop that far, but im not sure!

an other question i have is for pillowball mounts or how they are called.. there are some from Cusco for about 100$. My friend bought them, and he is racing on the Nurburgring-Nordschleife.. after 2 laps they were blown!! dont want to buy crap which do not hold minor abuse!

riverzendz 01-19-07 09:46 AM

I believe the RS*R's are 1.5" front drop and a 2.0" rear drop.

charge 01-19-07 09:51 AM

wow, whats the deal with the 2.0" in the rear?? dont understand.. for pure acceleration?? (weight transfer to rear wheels)

riverzendz 01-19-07 10:22 AM

Well, honestly I prefer it. Take a look at most other spring drops. The rear is alway sitting higher.

Tanabae - 1.5 1.5
Eibach - .8 .8
RS*R Down - 1.4 .8

Now take a look at your car. Naturally it sits higher in the rear and with the RS*R Race it evens the vehicle out a little better. Now, other than looks I would say weight transfer, acceleration, and center of gravity all play a part in the reasoning behind it.

Turbo II 01-19-07 10:49 AM

The Tanabe springs dropped my car 1 inch all the way around. A friend of mine has the RS*R and sits as low or lower. The total drop, or increase, depends on how worn out your original suspension is.

LAN 01-19-07 11:11 AM


That black car is spirited RX7 or Spirit RX7.
He used kyb/agx with rsr race it think.
He's now on some coilovers.

if so, it would be great.. a bit too low for a daily, but should work fine i think.

The picture you posted of your TII...that's not sitting on the GF210's is it? Looks much lower than a 1" drop.

Yeah it's on the GF210's. I measured it before and after and the front was exactly an inch, the rear may have been a hair more. Like I've said, what you end up with depends on how worn out your original setup is. I could DD the car but I have my 88 'Vert for that.

Sort of level shot....

I track the car at VIR, autocross it and take on obscene backroad runs... :)

The only problems I run into are inclined driveway entrances and an occaisional speed bump. I do get some tire rubbing on the front springs once in a great while on very very hard cornering at VIR.

riverzendz 01-19-07 01:12 PM

Wow. That's great. I think I'm going to go with the GF210's due to their price and availability compared to the RS*R's. I've got an S5 Red TII as well so your photos are much appreciated. Planning on doing some AutoX this spring, glad to hear they respond well.

charge 01-19-07 01:19 PM

is there such a price difference between tanabe and RS*R

as far as we talked about that stuff, im sure i want some nice RS*R Race in the near future! im looking forward to get some.

special thanks for the pics! :)

riverzendz 01-19-07 01:27 PM

Big price difference between the two. It's about a $150 USD price difference, here in the states at least.

charge 01-19-07 01:30 PM

what?! the RS*R are about 350$ then? the tanabe are for 200$ on their side as i remember

riverzendz 01-19-07 01:33 PM

That is correct. IMHO you get what you pay for but enough people have spoken for the quality of Tanabae for me to bite.

charge 01-19-07 01:39 PM

an other question i have is, why are the stiffest replacement springs (RS*R Race) near half the spring rate of for example Tein Super Street with 9,0kg/mm front and 7,0kg/mm rear.

what is it all about the Coilovers? why not koni yellow, or KAYB AGX with replacement springs like RS*R but as stiff as coilover springs?

Turbo II 01-19-07 01:55 PM

I think pricing was about the same between the two brands when I was looking a couple of years ago but like I've said, I could/can never find the RS*R's in stock. It's what I wanted to go with but nobody had or could get them so I went with the Tanabe set. I've been real pleased with them so far and the AGX shocks but wouldn't mind trying them out if someone ever gets them in stock. Hint hint nudge nudge.... ;)

Speculation answers from me on the following....

The benefit of coilovers is being able to corner weight the car and set it up as needed. If you're doing alot of track stuff it's worth it, otherwise overkill maybe for the street.

The Teins may be track springs I'm guessing where the car is slammed to the ground and you need the stiffest spring in the world to keep from bottoming out.

charge 01-19-07 02:07 PM

like Mindspin311 said before, RS*R should get some Race - springs in stock again in about 2 months :) im really looking forward to it. But also im looking for camber adjustable pillowball upper mounts, since i dont want to fuck up my tires or suspension if i run over curbs :(

Turbo II 01-19-07 02:14 PM

With a 1 inch or so drop you will need a rear camber adjuster but pillow ball mounts might be a little over the top, nice to have though. I'm stock other than a rear camber adjuster and tire wear on the front and rear has been extemely even (full digital alignment at a great shop).

charge 01-19-07 04:36 PM

haha sorry, i have been waiting long to get the lip.. finaly a got a whole car with it :)

Spirit Rx-7 01-19-07 09:58 PM

good luck finding a set of rsr race. with an extra hundread i think? you can get a set of GC coilover sleeves for the agx, and you can pick any spring rates you want.

charge 01-20-07 03:33 AM

hey where could i get those coilover sleeves? since in germany we have to drive legal parts, i could use german coiloversprings, that would be perfect! :)
