Hi all,

following the thread (as I can't still post there) http://www.dsmtuners.com/threads/3g-upper-lower-control-arms.351043/ I wanted to share my findings for all European guys here.

As you could expect we don't have many 3.0L 3G Eclipses or Galants in Europe, so there's a challenge to source a 19mm rear sway bar (2.4L 3G Eclipses has 18mm sway bar). So after deep research I've found that all European 8G Galants (1997-2003, all trims and engines, including Wagons) has 19mm rear sway bar and some of them has even 20mm ones. The rear chassis/suspension setup on 8G Galants are practically the same as on 2G Eclipses/Talons.

Here are the OEM numbers and modifications you can look for:
MR297627 - 20mm; CENTRAL-EU MODIFICATION: SNGEDL6C, SNGEQL6C, SRGEDL6C, SRGEQL6C
MR272712 - 19mm; All Other MODIFICATION: SNGEQL6, SNGEQR6, SRGEQL6, SRGEQR6

You can take upper/lower control arms of any 8G Galant too as they are tubular also as mentioned in the previous threads. If there will be a request for a full OEM code list for this setup- I can source it.
 
That's great information ZyXEL! I'm still waiting for someone to cross reference some tubular front control arms as the uppers are discontinued and never come up for sale.

Which front tubular upper control arms are you talking about?

So far as I've seen searching, the only upper front arms that fit a 2G are 2G (which are still available) and the aluminum SPC arms which were discontinued.

I believe everything referenced here is for the rear, not the front suspension. Also I don't think anyone has tested "stronger, lighter or both"; therefore presently just different & the ability to get more options for large anti-roll bars.
 
So is tubular implying stronger, lighter or both? Or just a better design overall?
The weight is the same- some say they are stronger but how you can prove that? I don't thing someone will bench-test them just to prove the point. From the theoretical point of view- they should.

Yes, all posts/upgrades are for the rear.
 
If you compare the upper stamped arm next to the tubular, you won't have any doubt.

The joint where the knuckle bolts in has one layer of steel on the stamped arm. The other arm has the tubular section run over the joint with tabs welded on.

The lower tubular arms look tiny compared to the 2g stamped ones. I didn't weigh those. 3G sway bar may not fit right depending on which exhaust you have.

So you've run this through some FEA and/or tested this? Post up your data from your investigation?

OEM part used on the heavier 3G car. YEAH, I'm sure they made the part weaker. Don't need any testing to tell you that.

Those weighs were off of used parts while they both had oem bushings installed still.

Based on the physics I can say they should withstand more "crushing" force in any direction. Although you do have a minimal vertical force and a questionable crushing force, more like a tension force on these as they are located on the top- that's why I'm not planning on changing mine.
 
How much is the 3g convertible V6 eclipse? Next line in your link. tks.

Anyway. I'm using them on my car cause the 2g look flimsy.

I'll risk my life that they are just as strong as 2g arms.

The only thing I can think of right now is the less rust overall (it's closed tube- better design, more rigid)- so less chance to snap it, hitting the sidewalk when you "drift" :)
 
So are we back to "different", not necessarily better? I thought the premise of this whole 3G UCA thing was, it was an "upgrade"? I guess facts don't matter, just looks & feelings?

I don't think there were tubular stock front upper arms that would fit 2Gs. I've checked most of the Mitsubishi models and they all uses stamped ones (at least the ones who share similar suspension), even the heaviest Galants.

In my opinion- you're correct. But it only applies for the upper arms as they do have tension, not the crushing forces most of the time. And you won't have that much force to feel the difference, unless you'll hit the sidewalk (as I've said previously). :)
The different story is with the lower arms and sway bars- that's why this thread (and the original one) was created.
 
Whatever. I believe this whole rear 3G thing was originally to help with upgraded anti-roll bars & being able to fit a 3G's but needing to switch the lowers to get things to bolt together. And do you really want to start making claims about the LCA's? If so, just post up your data & there will be no questions as to if this is "misinformation or hearsay". Lastly, why would you want to base your argument on stronger for side impacts? (Galant's, up to & including 8G's,are lighter than either of the eclipses)
 
Since it didn't get posted. 3241 lbs.

I'd be more worried about all these people doing awd conversions to spyders and driving them on the streets. I don't think they did any FEA testing to account for the extra weight.

From the physics- it's an upgrade. It's like an upgrade of 3 blocks worth of steel wall against the two one- it will stop the bullet (both of them) but the one is better at it and you would not necessary need the better one.
 
You should come over to here & run for a politically office. Our politicians don't like facts either. Just emotions & feelings will do. You'd fit in well.
 
I know know why mello feels the need to bust balls if you feel there weaker then don't use them Simple ain't it?.... He was simply posting up part numbers to help any one interested in doing this in the future.
