Anyone want KYB AGX's for the b15

VTspec · 2008-09-09 10:18:15

My 2003 spec v with 75k miles on the stock suspension will most likely be needing new struts soon. I really don't want to spend $750+ on coilovers. That really limits my options. I now can go with either kyb gr2's (not much better than stock) or I can spend $450+ on koni's and then buy blown stock struts and attempt to hack them up to get them to fit, and still run the risk of having them be noisy. My roomate is driving a 2000 subaru 2.5rs with SPT springs and you guessed it kyb agx's. It handles great, the struts were a direct swap and best of all they cost about $370. Why are there currently no offerings for the b15 platform? I got to thinking that if they have the agx for the b13 and b14 that they will soon release them for the b15. I got in touch with someone from KYB north america and here is what I sent them:
"subject: KYB AGX for sentra?

comments: I am an online member from both myspecv.com and b15sentra.net. These sites both cater to the 2000-2006 nissan sentra
(including the se-r spec v version). We currently do
not have a good strut choice for the b15 platform (2000-2006). KYB makes
the gr2 for our car, but not the agx. The only option for aftermarket
suspension is either expensive coilovers ($750+) or the koni
yellow, which is an insert and requires modification to fit.
Myspecv.com alone provides thousands of people that would be willing to
buy a direct swap high perfomance adjustible strut. Do you have any
plans in the works for this application? All 2000-2006 sentras have
interchangable struts so if one style AGX was made it would work across
the board."

Here is the response I got:

Brendan,
We do appreciate your interest in KYB and in the AGX. We currently are
not planning on offering the AGX for the 2000-06 Sentra. Although we are
currently not planning on it, I will pass your request along.

Thank you,

While not the response I was looking for I am wondering that if enough members sent emails we might be able to get things started. I am sure that they will produce the agx for the b15 eventually, but lets see if we can get things going now. remember that the nismo suspension set up uses eibach springs and non-adjustable kyb struts. If we got the agx we could get the same thing, and have it be adjustable for way less money.

wow, and i went looking for these last night and thats why i couldnt find them.

nobody else is interested in a getting a nice, adjustable, direct swap strut option for cheap?

Strychnine · 2008-09-10 14:54:20

I agree. I wish they made AGX's aswell. I'm not trying to spend the money for coilovers and I don't want GR2s because I might aswell buy OEM ones because they aren't any better and will ride like shit after 20k miles... I'm actually at 40k with my Sportlines with stock struts, and the ride is HORRIBLE. My car bounches all over the place. People flash their high beams at me at night because they think I'm doing it to them, when really I'm just bouncing up and down haha... Taking turns at a decent amount of speed, forget it. You hit a bump and the rear end wants to hop and come around.. The front end I can actually hear the strut be fully compressed and it's not a good feeling. I bet fluid squirts out every time haha... I don't really wanna mess around with modding the front struts to put the Koni inserts it. I may just get the Konis for the rear since they bolt right up, and then GR2's for the front.

Strychnine · 2008-09-10 15:18:46

My attempt...

Anthony,

Yes I did receive an email on this topic. We appreciate your interest in the AGX but we are currently not planning on offering it for that vehicle. I am not sure if the comments from the first email were posted or mentioned but this request has already been passed along.

Thank you,

Thanks Strychnine, I figure if we hammer them with enough emails they'll realize that there is a market. I mean the AGX would prolly only be about $120 more than the gr2.......for fully adjustable NICE struts.

ChRiSSpec_V · 2008-11-06 12:54:06

They make them for the B14, does anyone know how much different the struts are between the years? maybe a little modification they will fit?

VTspec · 2008-11-06 13:06:46

Can someone that is knowledgeable with the b14 chime in?

BlackoutV · 2008-11-06 13:16:03

the AGX from the b14 WILL fit. eric02specv is planning on doing a write up on them. he said his friend is running ground control coilovers from a b13, and using them with the b14 "top hats" (not really sure what that means) but he said it works. I'm waiting for him to post up about that. if they did make a AGX which is a direct fit for the b15 I would probably buy them, since i am looking into getting new struts for the spring/summer.

armadnigeneral · 2008-11-06 13:21:28

The Koni install really is not that hard. First of all there is no modification necessary for the rears, they're direct replacements. For the fronts all you have to do is just cut around the top of the strut tube to remove the shock, then drill a hole through the bottom. Done.

ChRiSSpec_V · 2008-11-06 14:33:19

Are the KONI's adjustable? and is there a write up? I personally saw the AGX's on a freind of mine miata and what a difference they make with just a couple clicks...

BlackoutV any idea when hes going to do that?

eric02SpecV · 2008-11-06 14:38:30

Here's a basic idea of what you'll need to do this.

I explained it poorly to dave the other day. I'll have Jim chime in and explain it fully soon.

Mike Kojima did this a long time ago, which is why i'm not sure people haven't heard of it.

B15 ground controls and then retain the stock B15 top hat. Then use B14 AGX's.

As I said, I'll have Jim chime in and make sure I have everything correct/other details.

The Konis are adjustable. The rears, unfortunately, have to be disassembled from the spring/upper mount to adjust, but the fronts are easily adjustable right from inside the engine bay. I just set my rears to 75% stiff and left them alone. Thinking about setting them to 100% soon.

Awesome write-up thanks alot! How do you like them for launching?? My car squats horribly when I get on it so I really need to stiffen things up. BTW I've got tanabe springs Good? or no good?

Ricer_X_01 · 2008-11-06 16:41:52

i was running b13 front and b14 rear kyb agx's with b14 ground controls with my stock b15 strut mounts from 2003 till this past summer and the car rode and handled great. everything bolts right on with no modifacations needed. the only problem i believe i ran into was putting the rear mounts on the agx's i had a limited amount of threads to bolt it on. so i pushed the mount down over the piston as far as i could till i could get the nut on and then just tighten the bolt. its that simple.

heres a pic for reference. notice the 4 way adjustable dial throught the strut tower.

here you can see the orange agx through the wheel.

hope this helps

ChRiSSpec_V · 2008-11-07 00:26:29

So let me make sure I'm getting this. All I need is to get a set of b13 AGX struts for the front and a set of b14 AGX struts for the back and they will bolt up and hold my current tanabe lowering springs w/o modification???

eric02SpecV · 2008-11-07 00:30:03

Yes, that is correct. It's been done by 2 other people that we know of too. One of them being Mike Kojima. Nuff said.

bmarcinczyk14 · 2008-11-07 00:30:16

just get the nismos. their not any more expensive than buying the koni yellows and a good lowering spring.

eric02SpecV · 2008-11-07 00:33:21

Thats a dumb statement, if people are looking to do this setup, then they are obviously looking for an adjustable setup.

The nismo shock/spring combo isn't adjustable.

Ground control/AGX is not only height adjustable, but the dampening can be adjusted also. Way more options, which is a good thing, if you know how to use it.

Ricer_X_01 · 2008-11-07 01:45:49

well technically, you could get b13 or b14 front struts as both will bolt right on. just the b13's are said to be a lil bit shorter and aid in extra travel when lowering. oh and i should have stated before, this works only with coilover sleeves because the spring seats on the adjustable perch on the coilovers and they come with a top hat that fits on top of the springs under the stock mount. so the spring its self isnt sitting on the agx's perch or seated in the b15 strut mounts. this is how you can use them. NOW, i have not actually seen a b14 spring sitting next to a b15 spring so i can not say for sure that it wont work. you might luck out and they might actually be the same diameter at the bottom and would sit/seat onto the agx's perch without unseating in daily conditions. hope that makes sense?

Ricer_X_01 · 2008-11-07 01:52:54

oh and i paid about the same back in 2003 for the gc/agx setup as the nismo setup costs. so for around the same price, and you are little mechanically inclined to take your struts apart, the gc/agx setup is really the way to go. also for anybody considering this setup, i ran 375lb springs front and rear when kojima suggested 350lb front and rear. so its really all in user preference. oh and i got the thrust bearings from a b13 which are metal vs the b15's cheapo plastic ones.

ChRiSSpec_V · 2008-11-07 10:08:22

GOTCHA, thanks alot. I guess I might order the whole AGX set for the B14 and see how my tanabe springs will do, if they dont work I'll just have to buy the ground control coilover (for the b14 right?). And yes I want the adjustability so nismo's arent what im looking for and I dont want to spend 1200 on teins.

yeah i used the b14 sleeves on my car. however this was before they had a b15 application. for anybody who has actually seen different applications of ground controls, they're all basically the same design and diameters. so one prolly could even use the b15 application too. im assuming the only difference would probably be the spring rates, but you can order any spring rates you want with any GC application at no extra charge.

Strychnine · 2008-11-09 21:10:06

Anyone know of Sportlines will work with the AGX's?

White_Spec-V · 2008-11-25 09:16:34

so what would be the best spring rate for the gc/agx setup? Mainly dd, but occassional drag/autox/road racing. Don't really care for a stock ride feel.

Tia for any suggestions

Chris, this will NOT work. You can't have B14 AGX's with ANY B15 spring. The agx's can ONLY be done with a sleeve coilover type.

Im !00% down for AGXs i had em on my 8g galant with Tein s-Techs and it road like a dream AGXS all the way so worth it!!!

eric02SpecV · 2008-11-26 00:01:03

The only reason one would go with these over koni yellows, is not only the ease of installation. (Bolt right up using the stock B15 strut mount) But the rears are adjustable without taking them off the car....unlike the koni's.

ChRiSSpec_V · 2008-11-26 15:04:33

Thanks eric, once I get some $$ saved this is the route ill be taking...

I think it would be possible to cut off the spring perch on the AGX strut and then weld on the perch from an old B15 strut...but I dont know if welding might hurt the shocks on the AGX...and if you are using the AGX anyways you are probably trying to avoid such work anyways.

yes indeedy. The Koni install really is not difficult, I don't see the big deal.

I will be going with konis on my new setup...just throwing ideas around.

ryoko · 2008-11-27 09:11:04

so has anyone done a write up on this yet. and can someone put together the exact partnumbers that work for this. this looks like a great idea. i was going to go with the koni's until i saw this thread.

mattmayhem · 2008-11-27 14:41:54

Dude, you just need the b14 KYB agx kit and you can go to the dealer for the front/back top mounts for the struts(not sure the codes...or reuse your stock ones) and a B14 ground control kit and you're good to go. I think from what they said the B15 Ground controls work too.

ryoko · 2008-11-27 22:29:52

looking like this will become my next project

Strychnine · 2008-12-24 00:50:08

Can someone post up pictures of the install for stupid people?

I'm not too familiar with the top mounts or how they would have to be switched over to the B14?

if you've never taken apart struts before, i wouldnt suggest it without somebody that has to walk you through it.
