Default Any benefit to using ITR rear lower control arms?

I am about to order a new suspension setup for my 96 Civic. I was wondering, is there any benefit to using the ITR rear lower control arms? I have a set, and need to know if I should order ITR suspension or just order the regular civic suspension.

Thanks

some shocks are either only designed for the box end (type R lca) or are easier to adjust, but otherwise no benefit.

ITR LCA's do not fit on to the 96-00 civic, so there is no benifit.

ummm the type r LCA's Do FIT the 96-00 civic.
they are better than the stock civic ones that is why they are on the type R and not the civic.
they are much stiffer due to their design.
the only thing is that you need the shocks to make them fit correctly.(shock designed for the type r)

Are the front shocks also compatible?? If I ordered a set of the omni full coilovers for a Type R, would they work as long as I used my ITR lower control arms?

Thanks

yes the front are compatable.
you are good to go.
enjoy them

according to the fact that I am an engineer and understand strengths of materials and how materials act under stress
I have actually tested them at a lab at CAL POLY, SLO
and guess what
MUCH STIFFER

aside from the petty comment, what you say is interesting. did you conduct an actual experiment with the actual arms, or just talking theory? please go ahead, and expound upon your analysis, empirical or theoretical. dont worry, i got my bachelors in mechanical engineering from university of maryland, perhaps not as upstanding as cal poly san louis, but im willing to struggle.

I must echo that I'm quite certain the ITR REAR LCAs do NOT fit the 6th gen Civics.

The front ITR FRONT LCAs do fit albeit a little odd, when it is likely better that the SiR/Si (EM1) FRONT LCAs would work best.

Stamped steel vs. the cast arms.... which I will assume with no empirical data or engineering degree would be a little more rigid

Does anyone know for sure??? Now Im wondering if I should replace the front lcas with Si ones too.....agghhh...lol, probably would be a good idea...

I am certain that the ITR LCAs will not fit.

The rear Xmember is not the same..... it is narrower, which is why the 6th gen lower arm bars are shorter than the 5th gen and DCs

If you do not have any provisions to mount a front sway bar due to your front LCAs, opt for at least ones from an EX but the best would be from an EM1/SiR/Si

Good info!! thanks

Guess Ill just go with the civic coilovers and aftermarket rear LCAs.

The 6th Gen EK civic has longer rear LCAs than an EG/DC. Also the lower shock mount is skinnier on the EK.

The front LCAs are interchangable, but if your car came with the stamped steel ones, you will also need to replace your front sway-bar & end-links. The stamped steel LCAs have a special sway end-link design that is not compatable with cast LCAs...

I knew you were an engineer from what you wrote so I was up for a little friendly dispute.

my car was up on jacks waiting for new coilovers so had extra time to play around.

But yes I did use the actuall type R lca's and regular civic ones also gsrs.
I tested them all of them by fixing the mounting point where it would bolt to the subframe and put stress at where the shock mounts.

The teacher that helped me laughed when I brought the three and looked at the type R one and said "winner, hands down" before we even started testing.

the regular civic one was weaker by about a little less than 30%
emperical evidence was just what the other people said stamped steel vs cast.
plus looking at the civic it has a point where it becomes really narrow leading to an inherent weak point. The Type R arm is a large box type design formed through a better process.

As you know stiffness is a function of a power to the fourth. for others reading this a circle of same material twice as big is 16 times stronger. that's why when they make huge sway bars they make them hollow b/c you do not lose much stiffness by getting rid of the weak inner part. like on my 350z it has huge but hollow hotchkits bars. Still stiff b/c of the radius.

I did all of this before I even took my strengths of materials class and was actually able to prove this after with the theory I learned in class. So the larger size of the circumfrence of the type R lca would tend to be stiffer. That is what I was testing. And theory was actually backed up experimentally this time.

plus I broke the civic one for fun.

No problem.
I am tired of the miss information as much as you.
Also I wanted to note that the civic lca was particually weak when stress was applied at the shock point as the lca was laid flat. My teacher asked if it would come into play in a braking situation. But I assume the forces applied to it in that direction are very small.

For a daily driver, a weaker LCA might be a little better. After all, I would rather have to replace a bent LCA than a bent subframe...
