I had the on car adjustable set up on my 16 Hellcat. They help but I ended up swapping all of them out to the AAD Performance ones. Over time the BMR ones started squeaking. I assume that's due to debris and water over time. Keep in mind that I swapped all 4 arms.

Have heard many say that the BMR's have failed , bent, broke @ adjusting point...AAD might be more expensive, but you will not have to worry about them failing.

I haven’t , that’s why I’m asking. I saw people had issues with the upper adjustable ones, I’m asking about the lower trailing arms specifically. 100 vs $1500, big difference there

My car had gnarly wheel hop stock stance. Half yer power (allegedly lol). Changed the springs also locked the diff at the same time. Poof gone. I believe the diff flopping around contributed but have no proof. Just a opinion

Definitely a price difference but the AAD are $379.00 vs $110.00 for the lower trailing arms only.

Buying multiple suspension pieces puts you to $1500+.

I believe you get what you pay for. If it's important, I'd go with AAD and not cheap out on a crucial part that has had not one but numerous reports of failures in the forums... my 0.02.

That’s what I’m asking, looking for the people who have had the non adjustable ones fail (haven’t found any) and people that have them to see if they did anything. Boxed steel should be stronger and flex less than aluminum

I doubt it’s the stock control arm that flexes… look at the stock ends (bushings). I could tell bmr ‘in car’ adj ends were weak in the pix. No need to search a forum ha. If I were you I would lock the diff before buying arms. Would put taller gear too

Do like I did n have a buddy super slo mo it for you ar the track

I’m not going to lock the diff, going to use p4d front diff brace and rear diff brace. Should tighten it up

I have run some BMR suspension parts on my Chevelle, and all of the rear suspension on my Mustang is BMR. I've never had any problems with any of their stuff, and I've always found them to be solid quality. I also don't street drive my hot rods much, so take that into account, too.

On the hellcat I have speedlogix trailing arms, as I did those first and then later swapped out the other control arms with AAD.
