Remember, the same links are used in ZL1 cars, which have a lot more power.

The bushings may - may - be another story. I would think in your case that involves drag launches primarily, the semi-trailing links would be the bushings to focus on. Again, though, do not use poly bushings in the back. I do think the cradle bushings would be an area to focus on. I meant to write that earlier. Not only will that help keep things pointed the way they are supposed to, but it might be a useful defense against wheel hop. The fact that GM puts aluminum bushings in the cradles of ZLEs probably means they matter.

Interesting. Makes sense. I've added around 100 horse and DRs, so I think I get where you're coming from. I don't really get hop on the street, but there isn't much grip, either. The track will be different. There's another factor Josh' got into, too, which I've been thinking about. I'm definitely installing my ZLE-bushings though. That's for sure. Thanks for your input.

I’d consider the BMR stuff mandatory at >700 WHP. At 650 WHP and below the stock stuff hung on ok but got a little squirrelly with DRs. As I hit 800 WHP the car was getting scary at times and the BMR stuff helped tame it down big time. As I near 1K WHP I couldn’t imagine still being on the stock stuff... no way.

I know some of the "sway" (as a lot here have used to describe the side-to-side motion under throttle) is due to my MT SSs, but it I really don't like the feeling. Even running about 20-psi on the street, anything above 80 is scary, IMO. I'm only around 700, so your experience seems to be confirming some of my suspicion. I know some of it are my 17" MTs, but if I can halve-the sway, I'll be pretty happy. Thanks for commenting. I appreciate anything you'd be willing to share.

LOL. No headers for me, but it will bug me just as much to feel rattles. That's good to know. I'm also considering the front cradle bars, too, so that rear cradle, with the ZLE-bushings, probably couldn't be any tighter when I'm done with easy to get bolt-on stuff. I imagine if I do find too much NVH, I can pull them off and sell, so all of this is good to know. Thanks for sharing.

haha yup same here headers and exhaust so i cant hear shit let alone any nvh

Has anyone tried/seen the Megan Racing toe arms? They are about half the price of the BMR stuff, which makes me a little wary, but I feel BMR and SPL are a little $$$.

ive had megan racing products on my old car and they were fine but for suspension parts i wouldnt trust them or godspeed i have all spl parts on my car its awesome stuff

I've had a fair amount of experience with BMR 4th Gen stuff. That was all good. Poly-end PHR, LCAs, etc. Never a complaint.

I've used some Spohn stuff on an H2 (LCAs, PHR). LCAs were rod and PHR was poly. Both were good. LCAs were expensive (IMO), but good.

I just received my order of the BMR stuff (all rear control/rods/trailing arms) - rod ends. I can't speak for any other company that I didn't list above, but this stuff all looks and feels good. I probably went overkill, but that's how I roll. I don't know that I have an opinion on if I got what I paid for, but nothing looks or feels cheap. Post-sale Customer Service was outstanding, too. To me - none of this was cheap, and I feel, in the least, I am getting a high-quality product.

FWIW...

I've put about 70-miles on the car and had an alignment now, and have a little feedback. To briefly review: ZLE cradle bushings; BMR rod-end upr control arms, upr/lwr trailing arms, tie rods, and front cradle braces.

The noise has increased some, especially on deceleration. Part of the increase, I am sure, is from the solid cradle bushings. However - I'm only detecting the increase on choppy surfaces. Not over expansion joints, or dips in the road, but where there is checking or cracking in large patches on the road. It's better than I was expecting, but more than I was hoping. If it doesn't get worse with more mileage, I'll be happy.

I can't get if it was worth it yet. I did other mods' that might influence some of the behavior of these mods'. I was hoping to get rid of a lot of the sway I was getting before. I know some of that was from the DRs, but it seemed pretty excessive. I'll learn more with more seat time.
