Help me build my rear suspension

[Bigdumogre]

Have been looking at BMR parts since Detroit speed looks amazing but very expensive and my car is just a weekend warrior. Would it be worth the extra $1000 for Detroit Speed? And is adjustable even worth it?

What I am looking at with BMR -

So I just did my rear end. May add more, but a couple of things...

Spherical, though good, tend to be noisier than poly.

TCA028 - Those LCA's are shorter than stock. They are meant for cars that are a bit lowered. And you're going to need the adjustable toe rods and end links to accommodate for them.

Here is what I have on my car in addition to Pedders coilovers. Front end additional changes are next for me.

TCA028 - LCA's.
TR003 - Adjustable Toe Rods
trailing arm not required. I may change at some point, but don't expect much of any difference.
ELK006 - end links. I haven't bothered changing the actual sway bar yet.
BK024 - Cradle bushings
BK029 - Diff bushings

Thank you so much. Bmr descriptions arent the best and was unsure of which to get. I will do the diff and cradle bushings when I get the gears changed. I did hit a curb over a year ago and want to change all rear parts in case something is bent. That’s why I was gonna do the trailing arms too

Without checking the numbers, Check Spohn.
They have some of the same parts for the Camaro that you are looking at.

And check your rear wheel width.

I am finding that these rear lower control arms do not fit wheels wider than 9 inches.
This is stated on some of the manufacturers website.

Sucks, mine are 11inch.

I skipped the LCAs and used factory FE4 units (2012 and later) in both my cars. Most guys do fine with stock LCAs and the need to change them comes in when you want to go to a 15 inch wheel for drag racing.

Full disclosure, both my cars are only lowered half an inch in the rear.

I don't see any sway bar changes, and I would definitely spend money there first. I run a 27/32 setup on the vert with 1LE shocks and a 25/28 setup on the turbo car with Z28 shocks and springs. The turbo car does have some understeer due to the staggered tires, but for where I am at right now, it's better that way.

In my case, I'm running 20x11 and 315/35/20. I am lowered somewhere around 1"- 1 1/4".

I have full BMR rear suspension, One thing I wish I had done was use their adjustable rear lower control Arm instead of their fixed unit. I had to really work to get my Alignment specs ( Would not have been an issue with my stock or adjustable ones but their fixed unit it is )

[Bigdumogre]

Thanks everyone for the feedback!

[Bigdumogre]

Does this all sound right - what I'm looking to order

BMR-TCA026R - Trailing arm
BMR-TCA028R - lower control arm
BMR-TR003R - adjustable toe rod

And this sway bar

The Detroit speed other products look really solid, but the prices are crazy and i feel like the bmr ones are probably just as good for my needs.

Looks good. I have to ask. How many miles on the car? Cradle bushings can make a big difference. Think about it. Everything you're doing is attached to the car holistically at the 4 cradle points. A good amount of lateral movement can come from here. I would upgrade those bushings to BMR poly or solids.

I have 80k on the car. I will be doing the cradle bushings when I put a tru trac and gears in it. Just thinking of stuff i can do in the driveway since i will have a shop do the rear.

So those are the lca that i run but if I was doing it over I'd get adjustable ones, if lowered and trying to get a decent alignment spec you'll need adjustable camber bolts as you'll run out of factory adjustment and even then I needed to make more modifications.

I am looking at the prices side by side and going to do all Detroit speed. All parts are adjustable and only comes out to $300 more than BMR and Detroit looks like much better stronger parts than BMR. The Detroit adjustable LCA is actually $200 cheaper than BMR and way beefer.

Now time to try and find a coupon code that works lol
