Question Questions on the KYB struts

It's probably been discussed, but I can't seem to find anything to answer this question. I see some of you are talking about KYB AGX struts, which I have gathered are adjustable, right? But I have also noticed, while looking for components and prices, that the Tire Rack has KYB struts, but they say nothing about being adjustable. The price for them also seems to be lower than what I have found for the AGX models. Are the ones that the Tire Rack is selling stiffer than stock, or are they the same dampening? Am I just better off going with the AGX's? Are the AGX's the best bang for the buck? Do they work well with the stock springs, or am I better off upgrading those at the same time? If so, what springs are better, H&R or Eibach? Also, where is a good place to order this stuff from?

Sorry for so many questions, but the Legacy is new to me, just got it last week, a 98 2.5GT w/50,000 miles. I absolutely love it so far, but the struts seemed to allow a lot of body roll at last weeks autocross, so I want to upgrade.

Thanks alot!!!!
Matt

AFAIK there's only one version of the AGX fron KYB.

You might see references to the GR2, the non-adjustable version.

The AGX is a great adjustable strut for the price. It won't last as long as the GR2 due to the compromises in adjustablity but it's worth it.

Won't last as long?

I have never heard that before. Where did you hear that?

Most adjustable shocks last longer because you can adjust them as they wear.

The AGX is rumored to be the same as GAB used to sell (for twice the price) and they had a good reputation.

Now that AGX has been on the market for a year or so, KYB is more confident in them and now offers a lifetime guarantee (it used to be only a 1 year guarantee).

Sounds like they should last a while to me. I would like to try a set for the subie, because the performance shocks I have used in the past (Koni, Bilstien, Tokiko Illumina) would last forever. Gotta like that lifetime warranty too!

The AGX's won't be listed for the Legacy (except for the 92-94 Legacy), but the ones for the new Imprezas fit just fine.

Another option to consider is the FHI/STi V5 dampers that a lot of people are using. I have them on my MY99 2.5GT sedan, and I think they are SOOOO sweet. They are large shaft (40mm I think) inverted style dampers, and they work incredibly well with my H&R springs. With just the springs and an 18mm rear swaybar, I got lots of roll into the turns, but with these dampers it's more stable, and just feels right.

They can be had for around 275-300 for all 4, and since they are Subaru parts, they bolt in perfectly.

Another option to consider.

I'm just having a set installed tomorrow, along with a 19mm sway bar, and Eibach Legacy GT spring kit. I'll report as soon as it's done. I got the AGXs as part of that JC Sports group buy, for $325 the set. I figured it was hard to go wrong at that price.

Mike from SPD mentioned that the adjustables probably wouldn't last as long, as they weren't warrantied for lifetime.

If KYB has extended them to a Lifetime, then who cares.

If they last two years and are replaced under warranty that's really not to bad.

Yeah, I saw that on the SPD web site.

Now that the AGX is not a brand new product any more and that KYB now feels confident in giving them a life time warranty, it shouldn't be such an issue.

Thanks,
Charles

Question

I'm wondering if the warranty was based on the assumption that anyone that buys an adjustable strut is going to race on them and that abuse makes early failure more likely? While the GR2s could go on a lot of "family" day drivers, anyone w/ AGX is likely to crank em up and rag on them every now and then.

I'm relating what a friend told me who talked to KYB. When the shock was first on the market, it had a two year warranty (I think) because it was new and KYB wasn't confident in it enough to do the life time thing.

Now that they have been on the market over a year, KYB is more confident to give the shock a warranty that this caliber of shock deserves. Check before you buy though! I bought Koni's for another car a year ago because I wasn't willing to spend that kind of $$ on a shock that the manufacturer was not willing to stand behind. They are looking like a good bet for the Subie now though.

Correct me if I am wrong, but I had what I believe was the GR2 (or something similar) 15 years ago. I was under the impression that while this was an above average quality shock, it was not of the caliber of a Bilstien, Koni, or Tokiko 5 way (all of which I have owned at one time or another).

I would expect the AGX to be competitive with that crowd, while the GR2 to be more for the average guy, or closer to the Tokiko HP (which is a pretty poor shock compared to the others).
