has any 1le owner replaced the rear control arms and links with the bmr stuff? or swapped out subframe/diff bushings yet? i mostly want to do the bushings to get rid of the clunk on hard shifts and obviously keep stuff from squirming under load. just curious

I've replaced all of the rear arms, but not the bushings.

[Ak1LE]

noticeable improvements? worth it at all? Are the ones for the ss compatible as well?

Just an FYI, we are in the process of making all the arms out of aluminum and prices will be comparable to whats available but lighter.

Little teaser.

The only thing I've noticed is slightly more NVH. I only replaced them because I needed the toe arms to get the rear toe in spec (with the increased camber). I just replaced all of them while I was back there. I can't say if they were worth it or not. From what I recall, they added ~ 7 lbs of weight over OEM.

Your car IS an SS, so they're compatible.

Waiting for someone to make a bushing insert for the OEM bushing (if it has voids) that should fix the clunk on hard shift.

OEM arms are already very light and strong, hopefully there will be a nice comparison.

A lot of people seem to think the stock arms are super flimsy, I want to know if there is really any truth to that.

Oh, they're flimsy, if you try to twist them. They're only made out of relatively thin stamped steel.

[Ak1LE]

my biggest concern is the clunk from harsh shifting, and occasional wheel hop. but if i can tighten things up in the process to make any improvements I'm down for that as well. keep us posted on those aftermarket arms as well! and to the guy saying it IS an SS...i KNOW this. but i was just making sure the 1LE didnt use bespoke links and arms and especially since an SS does not use our rear diff

but that's when you take them off the car and bend them in ways they weren't designed to. On the car when they are working in connection with the other arms are they actually bending? Part of me really doubts it...

You get what I mean?

The stock links are designed to twist to allow the articulation through the suspension stroke. Going with rigid links means you need a spherical bearing to give the freedom of movement.

The Moreno concept drawing looks good. The threads are close to the pivots to maintain a stiff link. They'll provide very consistent kinematics, that's for sure. As long as the spherical bearing they specify has good weather resistance, it'll be a winning product.

Out of curiosity, are the ZL1 or ZL1 1LE arms any different? If theyre the same and can handle the extra power, weight and grip (in the case of the ZL1 1LE) then I'd say there is no need to change em.

[Ak1LE]

Thats debateable. i mean yes the zl1 1le was fast around the ring but if these mods made it faster would you still say that? lol

I meant are the arms on those models any different than the SS 1LE? If theyre not, than obviously the standard arms are up to the task. If the ZL1 or ZL1 1LE ARE different, then maybe upgrade to those or the aftermarket if theyre equivalent. I dont know if there is any adjustability in the stock arms or not, but that may be a reason alone to "upgrade" as stated above. Keep in mind that heim joints arent those most street friendly. There will be more feedback through the joint and theyre not weather resistant. Perfectly fine for the track, but if this is predominately more streey car, they may not be the right choice. That is totally up to the individual owner.
