Parts that Suck

Post by **Phax** » Mon Jul 26, 2004 3:16 pm

I just have to rant because the money that I've spent lately on my car has been a waste.

First off, Yokohama ES-100 tires. These tires blow, plain and simple. I had a miscommunication with the tire guy. I told him that I wanted inexpensive Z rated tires. He thought that I wanted inexpensive V rated tires. V rated tires suck. Going from Bridgestone S-03's to the Yoko's just makes me sad... very sad.

Secondly, KYB AGX + Eibach Pro-Kit. That setup blows, big time. The springs are way too soft, and there's no way to dial in enough dampening with the shocks to compensate for the overly soft spring rates. I know that a lot of people on this board are running that setup, so I went ahead and go it based on all of the stellar reviews on here. My 1987 BMW 528 had a tighter suspension than AGX + Eibach.

I went with the Eibach and AGX setup because I wanted something more streetable than my kg/mm springs with blown shocks. I compensated too far back toward stock. Now I need to find something in the middle. I'm going to try to find some shocks that will work with my kg/mm DR21 Super Sport springs. Anyone out there have any suggestions? I know that I need to find a Tokico short bodied strut, or something equivalent. Help!!! :help

i haven't had the opportunity to drive on the eibach/kyb combo, but i've had good luck with the tein s-tech/kyb setup.

What settings did you put your AGX's at? I checked on Zilvia's site and the S-Tech have a significantly higher spring rate than the Eibach's. I'm thinking that the AGX's themselves might be a decent shock, and that I simply need to find a spring that is less Cadillac-ish.

2 front/4 rear. or was it 3 rear?

the S-Tech is a progressive spring. So it's not always on its ultimal rate.

hear nothing but good things with the agx+RS*R race spring setup. Not as hard as a coilover but still stiff

Post by **Hijacker** » Mon Jul 26, 2004 3:16 pm

the RS*R was my second chocie of spring. If I had a good spring compressor on hand, I'd buy a set of RS*Rs for track days. I think they're a bit too stiff for daily drivers

Sorry to hear about your tires and springs. (Bridgestones kick *** by the way, i have potenza re950's--super duper for year 'round).

I learned the hard way that eibach springs suck ***. just because a lot of people run them doesn't mean they're good. If you want something stiff, you have to get a spring with a linear spring rate. I got inexpensive Suspension Technique springs (lower 1.5" instead of the 2"+ of the Sportlines i used to have) and its a VAST improvement. I'm sure there are other linear springs out there, but this was the only one i heard of that was. I used to run my agx's at 3/6 with the sportlines (because the sportlines were so soft), once i got the suspension tech's installed i had to turn it down to 2/4 because it was so stiff!

Plus it only cost me $140 for all the springs (they sell in pairs).

Anyway, hope that helps.

sky. what spring rate are the sus techs?

agreed that linear > progressive. But I like progressives in that they give you a nice bit of both driveability and stiffness.

Not sure, but i think Exar-Kun has a sticky in the Supsension Forum with spring rates from different companies.

In theory, the progressives seem like a good bet--from a driveability standpoint, but I never found the Sportlines predictable. My car is my daily driver, and though the Susp Tech's are stiff, it feels as though the car has firmer handling and just gives you more feedback through the wheel. Not too mention Sportlines void your AGX's warranty and *will* make them blow prematurely (happened to me--thankfully only two blew).

Edit: Spring Rate Comparison:

EIBACH PROKITSpring Rate - F : 1.84~1.92kg/mmSpring Rate - R : 2.3~2.4kg/mmRide Height - F : -1.8" (eibach site) -1" (jnm240 test)Ride Height - R : -1.6" (eibach site) -.75" (test)

Pretty much anything other than stock springs void the AGX warranty.

The S-techs feel very predictable. They honestly feel like linears to me.

No, the warranty states that if the car is to be lowered, any more than 1.5" will void the warranty. The AGX's just can't handle any more than that.

edit: Yeah, actually, comparing the Suspension Tech's and the Tein's rates-- they look very similar!

Post by **Hijacker** » Mon Jul 26, 2004 3:16 pm

The only difference is that the Tein's are progressive. I like them as a street spring, but I worry that once I get the rest of my suspension package sorted, they won't be as good as I'd like. For now, they do what I want

Post by **skydragoness** » Mon Jul 26, 2004 3:16 pm

Stick with 'em if they're working for you. I like Tein, it's Eibachs i try to steer fellow 240 people from. Unless your'e running a dedicated track car, there's no need to run anything else but a good spring/damper combo. I don't understand why people think they *need* coilovers.

Post by **Hijacker** » Mon Jul 26, 2004 3:16 pm

because the magazines use them.

Post by **whiterps13** » Mon Jul 26, 2004 3:16 pm

get some tein basics instead of springs/shocks. you pay alittle more but get dampers that are matched perfectly with the springs.

PARTS THAT SUCK:99.99% of the MAF air filter adapters on ebay. For the KA, there is no bung for the IAS, thus causing many people who buy them to be pissed because their cars bog and idle bad. I found that FIPK pdf from K&N's website for the appropriate intake with CARB cert and used the diagram to fabricate my own bung prior to purchasing anything off of ebay using a MAF adaptor from a friend who works at autozone.

ANYTHING UNIVERSAL as well

I love my yokos, they're frickin awesome in the rain. Granted I don't have an SR, but the only place I slip is the drag strip where Silica compound doesn't exactly agree with already layed down old-school rubber (hoosiers, drag slicks). Ok yeah, I've practically balded the drivers front and passenger rear, locking up diving into turns or one-wheel-pealing my way out at autocross. What do you expect from a street tyre?

On another note, anyone have an idea or the spring rate for H&R sports (yeah, I searched, no info)

apparently not hard enough. In the Suspension forum, there's a sticky at the very top. It's where Sky C&Ped the info she posted earlier.

My issue isn't with top speed, I'm sure that they will hold up to 149mph. My issue is with the grip of the tire. As soon as you start putting any sort of lateral (sideways) load on the tire, they want to slip. Driving at 7-8/10ths feels like 10/10ths with those tires.

On the bright side of things, they have toned down my high speed tendencies. :rolleyes

does the speed rating actually affect how grippy the tire is? Like is a Z-rated tire grippier than the same tire but has a H-rating?

Post by **nissanflip** » Mon Jul 26, 2004 3:16 pm

the reason why tires are speed rated at a certain speed is because of the type of materials used in that tire... An H-rated tire will start to deteriorate faster at speeds higher than its limit due to heat and friction.... and so onAs far as grip goes... it all depends on what type of tire...

Post by **Fenvy** » Mon Jul 26, 2004 3:16 pm

I too, regret my agx + sportline setup, who ever said tein basic sucked shoudl be shot, I think I rather have that abotu now...

They are definitely stiffer than stock, but I have no way to prove that since H&R doesn't publish thier specs (at least that I could find, google, etc.) I have had people compare them to S-techs.

Post by **Hijacker** » Mon Jul 26, 2004 3:16 pm

I'm not certain on this, but I think Chet (Exar-kun) contacted the manufacturers directly regarding those numbers.

Post by **dreamsOfSkylines** » Mon Jul 26, 2004 3:16 pm

The speed rating has nothing to do with lateral grip. I had heard good things about the es100's and was considering buying a set. Antone else have experience with them? Also you do realize that the s03's are double the price of the es100's? If these aren't enough grip perhaps you should try kuhmo mx 's for a little more $.

Post by **rico05** » Mon Jul 26, 2004 3:16 pm

Hahaha

You can get S Tunes for what you pay for AGX + any crap spring that you guys get. Tuned for the S13 and properly valved. And yes, that ES 100s would be a drop from S-O3s. That must suck man. I do love my Azenis Sports tho. 10x better than ES 100s.

Post by **Fenvy** » Mon Jul 26, 2004 3:16 pm

I should have bought the s tune like rico05 suggested....

actually the drop is not enough for me, I wanted a 2 inch + drop badly because the 4 inch gap looks stupid

Post by **rico05** » Mon Jul 26, 2004 3:16 pm

I have 50 tall tires, imagine my sadness at the wheel gap. The drop dosen't even show since the stock gap is retained. Wish Falken made Azenis Sports in 205/60/15:( But the grip is worth it:)

The lesson I've learned from this is don't buy tires from thewheelsupply.com. I told the guy that I wanted a Z rated tire. He sold me a V rated tire. Anyone who sells tires for a living and is COMPETENT at it, would look at the customer's car (mine in this case), recognize that he's pulling off a Bridgestone S03, and at least mention to the customer, "You know these tires that I'm putting on there aren't even CLOSE to what you used to have."

I'm so freakin pissed. For $15 more per tire, I could have had some Dunlop SP8000s. I've had those tires before, and I know that they are good tires.

Oh well, it just goes to show, make sure that you know what you're buying. Never take anyone else's recommendation. This is the second time this year that I've been screwed by other people. It's almost as bad as when I took my car to the stereo shop and ask them to install some speakers that could handle the power put out by my amp. 6 months later, the speakers are blown because they didn't change the settings on the amp itself. Freakin, retarded, stupid, worthless... <grumble grumble>
