Don't fix something that isn't broke. GM's engineers know what they are doing.

If this were true, i and others wouldn't have constantly experienced the rear wandering under WOT. After adding the rear BMR components i have yet to have that issue. Just passing someone on the road prior could be scary at times.

Had mine go damn near stripe to stripe at Bowling Green last time I ran, so I put all the BMR parts on my Christmas list for this year.

Exactly what I have been experiencing in mine also.

I believe the biggest factor is the rear rubber cradle bushings. I would start there and then see if you need more than that.

just that one change without any of the arms got rid of 100% of the rear side to side issues for me.

Adding arms, introduces more maintenance of having to grease them up to avoid noises and binding as time goes on. The rear cradle bushing upgrade is a one time do it and forget it.

I'm doing all the arms as I have done the complete BMR package in my 3rd and 4th Gen F-Bodies with great results. The greasing doesn't bother me as this is my fun car and not my DD. The good news about getting all the arms is having poly bushings already. Over time the rubber in the stock arms will deteriorate and while the cradle would have already been handled, you'll start loosing feel as the trailing and control arm bushings degrade.

Makes sense. I was originally going to do the arms as well, but I am happy with the handling traits with just the solid rear cradle bushings.

I think I am done putting any more money in my car, I have done pretty much all I need to do to be happy for the next 3 years. I'm starting to save for a PDK GT4 or C8 Grand Sport.

I did the Bmr springs, upper control arm, upper trailing arm, lower trailing arm, and rear cradle lockout kit. Made a world of difference in how the car does under power.

I had a relatively bad experience recently with BMR, details at the thread link below:

Do you still intend on doing a review? You're making great videos, IMHO.

Yes, So far so good with them though. Thank you!

Having spoken to BMR, the Cradle lockout kit makes the biggest difference. However the Black Friday deal I got on the control and trailing arms was too good to turn down. Contemplating the BMR springs as well (especially if I go 305/325 on the 20's) which should do. IMO the affect of "braces" is negligible compared to the difference the bushes make. With bracing your stiffening something that wobbles. With bushes, you're not wobbling in the first place.

Yes but you have to start somewhere. Braces do make a difference but i agree that bushing are much better, but also much more expensive. At 360 bucks for the cradle lock out and 108 for the brace, some people have to start small. I do feel a difference with just the braces so i know the cradle lok out will be i BIG difference.
