Have a Nice Day? Can I use different strut mount brand on rear and front?

Hi all,

I tried searching using keywords "different mount" and didn't see anyone asked this question before.

Suspension gurus, please help

background - bought 05 wrx sedan with 40k miles with OEM spring, OEM strut, OEM strut mount, with Tein S lowering spring. Back strut mounts were broken, so I changed both rear struts and strut mount. Struts were replaced with KYB GR2 and mount were KYB mount. Currently, still retaining the Tein S springs.

Front suspension are stock struts, stock mount and Tein S spring. I am hearing clunking noise from the front as well and figure I would replace them soon in the future.

I know the springs are bad, I bought it that way. That is why right now I am trying to swap out the springs for one that will not blow my struts and strut mount. It is my DD and I do not track it, no autoX.

Since I replaced the rear strut mounts with KYB mount, can I replace the front mounts with Group N strut mount since I heard they are better? Will the front and rear mismatch cause problems?

I want to use the OEM struts for front and rear, and replace the Tein S spring with a better set of spring. I like it more damp and comfortable ride.

Suggestion please?

come on. I didn't see anything in the rules regarding gr2 struts? group n mounts? or sti take off springs?

I know my springs are bad for my struts and not supposed to be mentioned, but I want to change them out.

before closing, I still couldn't find my answer yet.

Can I use KYB strut mount in the rear, and Group N strut mount in the front?
(because I already replaced rear strut mount last week, and now thinking of front strut mount)

Were you going to answer his question or just run around screaming, "OMG teh n00bs" . You don't need to be so harsh on the new guys. People do ask for spring recommendations quite often, but you never bothered to address his question about mis-matched strut mounts front and rear .



OP, yes you can use the Group N on the front with the KYB (stock) mounts in the rear. Nothing to worry about.

tq so very much

So I researched entire morning and decided to go with the following setup:

(I believe 04-07 sti springs will work with my 05 WRX)
front : group N strut mount with either stock strut or STI strut + sti springs
rear: KYB strut mount with KYB strut + sti springs

according to this thread:

If you already put the GR2 struts in the rear put the same ones in the front. They'll work with the STi springs. You can mis-match the strut mounts, but you don't want to mis-match the struts. STi struts are much stiffer than the GR2 and wouldn't work out very well. The '04 STi struts are also the ONLY STi struts that would fit your car and they are a bit hard to find these days. A new pair of GR2's for the front is the best, cheapest option for you.

ok, now that I know the STI springs will fit on GR2.

I found out that the springs will be too stiff for the GR2? Will it destroy the strut and cause premature wear?

It is my DD and I don't want to deal with blown struts in the near future. Or will the WRX OEM springs work just as good ?

Why not take advantage of having it apart and pick up a set of Swift springs or Epics? I hate doing the same job over and over.

It sounds like you want a nice ride and those two brands have the best reputation for that. Sell the S-Techs, and you'll have money towards set of quality springs that are a perfect match for the GR2's.

i will be taking it to a local shop to install the springs. I don't know how to do it myself.

Yes, you are right, I just want a nice ride. I was thinking about the sti take off springs (black) because I will be able to get it locally from a forum member. Albeit, it is a 1.50 hours drive.

I just want to make sure it won't wear out the struts and strut mount pre-maturely due to the stiffness of STI springs.

If it will, then I will research into the switch and epics springs

rather than making a new thread, I'm just going to post my question here since it's touched on in this post, but mine is wrx -

I was hit by a car that left the scene and I'm stuck with a bent left rear strut that insurance will replace, and a right rear strut with 100k on it that insurance wont replace.

Progressive quoted me $150 for an oem replacement, but I asked them and they said I could order any strut I wanted using that allowance. I'm debating these two options:

1) tell them to put in an $80 KYB GR2 and save as much as I can on the right one I need to buy

2) KYB AGX's are $123 on tirerack. I'd replace the rears, but I'm not all that interested in doing the fronts yet. It would probably have to wait until winter or next summer. Plus one of the front fitments is on backorder anyway....

I'm keeping stock springs, would there be any problem with running oem struts up front and AGX in the rear? I just hate the thought of putting GR2s on now because I didn't have time to budget for the strut replacement, only to replace all four at some later date in the not too distant future since it was on my plan for some point in the next year or two anyway.

Thanks for the input

I dd the car, TSD, and if I can ever make it to a rallyx near me I'll enter for fun, but not trying to win my class or anything. STi strut/spring takeoffs with a small lift spacer was what I was thinking of doing before I needed a strut NOW, if that helps.

You can probably find some damping setting on the AGX that will work with the stock fronts. If you don't have the time and funds to replace the fronts within the next few months I'd go the GR-2 route. GR-2 are basically a stock strut without the dealership price tag (KYB makes the OE struts). They'll certainly work better with the front struts. Though at 100k miles on your suspension they are all most certainly in need of replacing.

Is your insurance company going to replace the strut or just cut you a check for the value of the OEM piece? If they will write you a check for the $150 replacement cost take that and you're half way to a complete set of GR-2's.

Thanks for the advice. I agree, the cheapskate in me says to just get GR-2s half off. But the car guy in me says now's the time to upgrade. Time to talk to my other half. Budget could be tight, but may be doable.
