Eibach Springs + KYB AGXs - Toyota Nation Forum : Toyota Car and Truck Forums

Donald · 10-04-2009, 08:23 PM

I just installed a set of Eibach Pro-Kit lowering springs (#8212.140), with with a pair of KYB AGX shock cartridges in the front (#765015).
These replace a set of Intrax lowering springs with KYB GR-2s all around.
I still have the GR-2s in the back.

I have only driven about 30 miles on this new setup, but was very pleased with it from I got out the driveway. The AGXs were set at the #2 position (it has 4 positions to adjust damping). The difference with the damping compared to the GR-2, is remarkable at that setting. A lot more damping and spring control.

I will be trying other damper settings through the week and will post my observations as I go along.

The Eibach springs seem firmer than the Intrax springs, but the front springs don't give as much drop as the Intrax springs did. This set of Eibachs are supposed to give a 1.0" drop all around, but it looks to me as though the front didn't go down at all. The rear is definitely lower.
Tomorrow I will take measurements, and hopefully somebody else with a GT-S with stock suspension can give a measurement comparison.
If my memory serves me right, the Intrax springs gave a 1.6" drop.

I have an autocross event this comming weekend and will see how this new set-up works out compared to the Intrax/GR-2 combination and the K-Sport coilovers that I had on before that.

Anybody who hasn't followed my K-sport saga can see that thread at the link below.

Any plans to replace the GR-2's with AGXs as well in the back?

SuperRA · 10-05-2009, 01:23 AM

Are you selling the Intrax set? I may be interested if so.

I have intrax on my GTS and the front drop was way too low for me. I made some 3/4" spacers and it sits just perfect now. The wheel well gap is equal to the rear now

you can't get AGXs for the back.

this makes me look forward to my koni yellows even more

Really?

That's weird how KYB would have them for the front and not offer them for the rear.

well they technically don't make the for the front either... they just happen to cross reference with the front cartridges for an MR2

***PhatRoyale*** · 10-05-2009, 03:48 PM

Interesting... never knew that.

***REN69*** · 10-05-2009, 07:28 PM

haha... welcome to the AE92 section.

The front KYB GR2 cartridge cross references to the front KYB GR2 on the 1989 Celica GTS and the 90-93 SW20 MR2s, which of course are cars KYB sells AGX for.

BTW I just noticed that Tire Rack is carrying KONI Sport cartridges for the SW20 MR2, Manufacturer Part #: 8641-1220SPORT... $195 each though.

but yeah that would also fit.

something new here to be learned... I'll back home to gear up for trying

They carry the 8641-1146Sport too... which is this koni yellow made for the GT-S :P

it's also $195...

my rear koni yellows are on backorder

they have been for like a month or 2.

Ghostyman · 10-06-2009, 12:49 PM

Hah, that's great to hear about the MR2 setup. That means when I replace my MR2 suspension, I'll be able to use my fronts on my AE92 and the rears match up to my RA64 Celica front. Hooray for cookie-cutter cars.

Createdtoburn · 10-06-2009, 05:11 PM

Hmm you mentioned the front doesn't look any lower. That's what makes me not want those Eibach springs, I hate the fact that stock my car looks lower in the back then the front already. I want some springs that will lower like 2in in the front and 1in the back to even it out a bit. Especially when you got 4 people in the car the back just drops even more making the front look retarded. Any options?

Donald · 10-06-2009, 05:47 PM

I have tried all the adjuster positions and conclude that when KYB set them at position #2 they knew what they were doing.
Position #2 is perfect for the street, #1 is softer but still very good, 3 and 4 get progressively harder and are a bit firm for daily driving, only because 2 is so good. Positions 3 and 4 are not uncomfortable, just a little jiggly. They just feel like your tires are over inflated, probably perfect for autocross.

I would like to get some adjustables for the rear too, (maybe a full set of Konis) but this set-up will have to suffice for now.
The rear feels a little soft, but I doubt that someone driving the car would know that the shocks are different if I didn't tell them. Maybe somebody who drives competition would feel it, but I don't think the average person would.

The front and rear, measured at the bottom of the rocker panel seam is approximately 6 5/8"

Front height measurement

Rear height measurement

I wanted to take some photos to show the stance, but it is raining here now. I'll try to get some later in the week.

I am thinking seriously about selling the K-Sports, but I haven't decided yet. I might get another car just for autocross but I have to see how much over time I can work in the comming weeks. Jmaz asked for them first, so he will get the first option, but I will let you know when I decide.

I wish I had gone this route from the begining, instead of spending a year and a half and all that money trying to make the K-Sports work. This set of springs and 4 Koni yellows would have cost me less.

Eiback pro-kit lowering springs - $199 + shipping
Koni yellows about $200 each.
Total - approx $1000

K-Sports - $850
6 pairs of Eibach springs (different load ratings @ $59.99 each) - $720 + shipping.
Total - approx $1600

Oh well! Learning experience.

Anybody want a pair of GR-2s for the GT-S front (cartridges) ...... almost new ...... any reasonable offer + shipping.

I had the Intrax on a sedan before, and because of the front drop being more than the rear, I cut one coil off the rears, and it brougnt it down to a reasonably level stance.

Because of cutting the rears, it upset the balance front to rear making the car oversteer too much when I am doing slaloams in autocross, the rear end wagging too much. That is why I decided to replace them with the Eibachs. Otherwise they worked great on the street.

Anybody want to buy a set of Intrax lowering springs? Any reasonable offer + shipping. Original price was $200.

Aw, I was hoping to get an un-modified set.
