Wow. You have the whole package. I would like to hear your thoughts on how your car works after installing all that at once.

BMR recommended rubber boots for the toe rod ends. I got mine from Summit Racing. I can't remember the part #, but BMR knows.

I did a search and saw these recommended.

Also saw some people using this spray.

Got my kit in yesterday. The only issue i had was the front wouldn't drop quite enough to get the upper piece in there. Not too hard about an hour.

Were you able to do one side at a time, or did you do the front first and than the rear?

WhiteMale · 03-27-2023, 10:17 AM

I did the fronts and then the rear. I had to use a pry bar in there to push down the cradle about a 1/8" to get that front upper in there.
Needed a punch and hammer to get the "bullets" in that other bushing. Greased them up and they'd go about half way, had to hammer them in with a 10" socket extension.

So far the kit feels great. I also put in the BMR non-adj rear sway bar, adj end links, and topped it off by putting on my summer wheels and tires.

So I am a bit late in discovering this kit. Will very likely order this soon for my 2017 SS.

I don't track my car; it is mainly a DD and weekend cruiser.

But I had a bit of a surprise when I changed lanes on the interstate. Rear of the car just felt weird. The road surface has grooves and I think the rear of the car tried to follow the grooves and the movement in the cradle allowed it to try to do that for just a moment.

Question: I know that the cradle bolts are torque to yield. Anyone just re-use the original bolts and use a torque spec of "gud'n'tite"?

Okay, watched the install video that was linked in a previous page and they re-used the bolts. I will do the same.

Don't reuse the bolts. They are cheap and the old ones are stretched past their yield point.

arpad_m · 07-06-2023, 08:07 PM

I'm with Mark on this one. These bolts are cheap, last time I checked they weren't on backorder, and you can rest well at night knowing you didn't compromise your rear suspension.

Just order the OEM replacements

My lock out kit is in mail and new bolts are ordered, they only cost $24 Canadian so almost free in American dollars! I’ve heard people say some are hearing squeaking noises after install, so I’m going to use dielectric grease on everything because that stuff doesn’t dry up like regular petroleum grease and it will not affect the original rubber parts on the cradle

Just installed, very noticeable!
