C-pillar bar for 240SX fastback.

[dualn1exhaust]

Can anyone post a picture of a fastback with the C-pillar bar on? I searched the forums for one and no luck. I don't want to buy one if it won't fit the fastback since it says "for coupe only".

[Slappy]

There are C Pillar bars for the Hatchback. They actually work on the hatchback , but not so much on a coupe. Open your hatch and step to the side of the car , see all that open space? Non of that open space is present on a coupe , so you really dont need a bar. And please , if you get a C Pillar Bar , dont use it as a harness bar.

[dualn1exhaust]

Ahh I see. Hahah, no I won't use it as a harness bar because that doesn't seem safe at all.

[SHIFTVAX]

Thats the only pic I have of it.

^ back seat can't stand up its self?

[formulaSX_kris]

mine is a megan racing one its out of the eg6..here's the pic

Does nothing and is a waste of money. I have one too, but luckily, didn't pay for it. Spend your money on something worthwhile like swaybars.

The bunge cord was tied to my sub to prevent movement !

Do C-pillar bars even do anything suspension wise, or do people just use them cause they look cool?

[Didderson]

They help out fastbacks the most. Coupes not so much because of the nice already present frame.Trick to getting the coupe C bar to fit is using 1 stock 91-94 seat belt bracket and the other side bare metal/frame and your 'coupe' designed bar will fit perfectly!

[White Comet]

^ its true thats what both of us did

[SHIFTVAX]

I think it helps a little, I have a strut bar up front so I cant tell which makes for the most stiffer handling. But I wouldn't say its a waste of money even though mine came with it.

Maybe it does 'nothing' for a guy with an s14 coupe which already has:A stiffer frame than an s13 especially if it has lower miles.A coupe design with a trunk instead of a pickup truck bed design.

It mounts in the seat belt holes for the C pillars... How is that not the strongest point on the C pillar? Drive my s13 fastback, it does help. It's like having this design: |_| which is a fastback area without a c pillar, versus a square. Which would you assume a greater tensile force can be applied to?

If it does nothing why do you have it installed.

^^^ Whenever the lugs on my strut bars get loose and I have to tighten/adjust, I do feel slight differences in handling. I suppose, those differences would be magnified if they weren't there at all.

I have sway & strut bars. I think they both help on a fastback.

[Dano]

I guess if that's about the only chassis bracing you have then it may help, but they're cheap (especially the megan racing pieces) enough to the point that they bow under very little tension. If you have any other significant (and more important bracing, then you won't notice crap from this. Now... if you were to connect that with a real, solid, piece in a hatch, I could see how you could gain from that. But as for these cheap pieces of junk, save your money for something worthwhile. It's makes a better clothing rack than it does a structural piece. The reason mine's still on the car is because a) i'm too lazy to remove it and b) I enjoy it at night because it blocks SUV and truck headlights in my eyes. Which it also does better than add to the structural rigidity. Do a solid rear strut bar on a hatch and you'll get a bigger improvement, guarenteed.

[Didderson]

You've got some good points there Dano. I agree you probably don't see as much improvement with this as with a rear strut bar, but I have a cheapo ebay strut bar that came w/ my car when purchased so I have yet to improve on that mod.

As far as the strength of these bars goes I'm not sure about them being weak. Sure they are weak as hell under shear forces like bending, but my friend mrgreeneyes had one on his old hatch, the car hit a pole sideways in the rear (not his fault, his idiot friend was driving) and the bar actually transferred the force of the tree to the other side, bending the c pillar outwards! It was quite a sight. He might have pics of the busted up car on here. So in terms of tension and compression, which is all the bar is designed for, I think it works fine.

I was assuming it's only under tension because of this theory: http://www.e30m3performance.co...y.htm

I forget who did the math for it, but it's a common thing if you search the internet some physicist did calculations.

On a side note, mrgreeneyes doesn't want to run a strut tower bar for the rear of his s13 coupe. I said he should but he says nah because the coupe framing is much better. But in my argument I stated that the framing actually isn't connected to the tower, making his point void but who knows. Did you notice a pretty nice difference w/ a strut brace on your car? He put his battery between the struts so we'll have to get a slightly higher bar for this to work.

lol a clothing rack. that's a good idea. now i can move out and live in my car finally

I have one. It gave me like 5 more horsepower

[White Comet]

you beat me to it tom, i was also going to mention how keegan's held up in the accident. i noticed a difference with the bar, but we'll see how much better it feels after i ditch the ebay rear strut bar for my cusco traingulating bar

[Dano]

after i ditch the ebay rear strut bar for my cusco traingulating bar

That's a nice piece

[White Comet]

That's a nice piece

hah not to thread jack but u'll never guess what i paid for it

[Felipe]

I have one. It gave me like 5 more horsepower

it gave me 10 stiffpower to the frame!

[Dano]

hah not to thread jack but u'll never guess what i paid for it

Free.99?

Real guess: $22.04

[White Comet]

100% free. i didnt pay anything for it, not even shipping

[DS13]

^ one lucky guy you are mister

Quoted for truth,

You are better off getting a cusco tri bar for your rear trut bar

[White Comet]

^ i have both the c pillar and im about to install the cusco tri bar. i have 1 sway bar already, then 1 more to go

[l0nestar]

... The reason mine's still on the car is because a) I'm too lazy to remove it and b) I enjoy it at night because it blocks SUV and truck headlights in my eyes.

Would you use this as a base for an in-camera, or is it too far back?

Wait, it is on the C-Pillar... answered my own question

[DS13]

i traded somethin for a c pillar bar turns out it didnt fit my car so i did some customizing hahah
