Strut tower Bar

I found a good price for one on the front, cash to spare

Will I notice any difference?

I know they make the body flex less, theres a few more things you can do to help that too.

I think I can feel the body flex, taking turns going 60 or so on the mountain roads but I'm not sure if its the front or rear, so if I only got a front strut tower bar would that negatively affect the rear maybe? I plan to get a rear as soon as I find a good price anyways, it should be here tmrw.

Just wonder what I should "feel" for.

yes.... if you just put a rear strut bar, your car will inherit more oversteer, if just a front, your car will inherit more understeer when pushed hard. It all comes down to chassis flex. Its mostly how you feel about it, in my old 240sx i would pull the front strut bar off and put a rear on because the chassis flex in the front would help make the front grip and rear come out.

Of course you wont be able to tell from just street driving *mentally you will think so*, until you push the car hard.

lolol mentally think so..

I hope to someday hit a track but I just **** around on these mountain roads, never really any cars and I've been on them roads since I was a kid.

Sounds good on the front if it'll understeer alittle more

*waits for package

The problem with chasis/soft bushing flex in a car is that it changes the geometry of the suspension setup. You can set your toe/camber/caster with your car sitting on an alignement rack, but if you have a lot of chasis and bushing flex in the middle of a corner it will deflect your suspension in a different direction.

After you stiffin one part of your suspension, another part will flex. Unless you have a dedicated race car you have to compromise some parts of the suspension.

How tight are the strut tower bolts supposed to be?

The bar doesnt fit perfectly, so i tightened it till it was tight... bad?

No, that is good. The bar is supposed to press on the towers.

Yeah but the uh part that goes around the strut towers... it was cut wrong a tad, so i shaved it as much as i could with a dreamel tool

I got tired of doing that though so i Used the nuts to bring it down a tad...

How tight should i make them though im confused, I did it till I cant turn them any tighter without using excessive force... you know what i mean?

The bar atachments were probably machined properly, but over time the towers on the car will tilt inwards, therefore not allowing the bar to be attached easily, or positioned with the studs. Many buy the adjustable bar so as it will fit easily. If you jack up under the front crossmember the towers will tilt outwards slightly and then you might have a perfect fit without any machine work.

He's saying the holes in the plate that mounts to the strut tower were drilled wrong.

I know what he's saying, but with a non adjustable strut bar, the plates won't fit on the towers because the 20 year old cars are tired and the towers are, shall we say closer together, hence the holes need to be enlarged, or ground away to make it fit.
At least that's my take.

Yet no one tells me how hard to tighten the nuts ~_~???

The parts that go on the towers, i put the bar on after... its adjustable fully....

The whole in the center was 2 hairs off on the inner part, you know how the outer part goes STRAIGHT down, and the inside kinda curves down, it didnt fit on the curve, I didn't buy a "Good" strut tower bar as I thought well if its cheap **** itits not a "butt dyno" bolt on, might not do **** as far as I know :P

I think what I did is finel I just didn't want to over tighten the nuts, I shaved down the mounts so they fit alittle better, but if you can over tighten the nuts easy then I'll shave it down alil more so its not such a tight fit...

I just don't want to F up my car over some bolt on.

Hand tight with a normal 3/8in rachet(sp) will put you close enough, prolly a little tighter bad wont do any damage

Went for a few fun drives, nothing bad happened.

I think I can feel the bar, driving down the street when everthe front tires hit dip/bump it makes the back dip more it seems like, it just feels stiffer.
