You either have to live with it, or upgrade to either BMR's rear cradle lock-out kit OR GMPP's ZL1 1LE solid rear cradle bushings.

IMO, all Camaros should have the solid rear cradle bushings, however I think GM's thinking was to save it for only the top dog ZL1 1LE. I think it should at the least been standard on the SS 1LE as well.

Thanks for the heads up!

Appreciated.

Thanks for the post. I think you are dead on and had I kept the car this probably would have been the answer.

I know it's an old thread but I promised when I came across the alignment specs I would post but since then there have been quite a few others with this same issue.

Thanks!

They do not, that is the beauty of it and also why I say it should be standard across the entire Camaro line.

There are no downsides, only improved rear-end stability and composure in the latitude plane.

Well, it's worth mentioning GM says it'll void your warranty to install them. Not sure if that's just for the rear end, I'd guess so. But as you said, it's likely to go unnoticed.

Sucks it takes so much time/effort to install them...

The cradle bushings in the IRS suck. The rear cradle and the toe rods and control arms are junk. Spend 700 and get BMR stuff and ZL1 1LE Solid Rear Cradle Mounts from gm for 375. Mustang and camaros IRS suck when it comes to the bushing causing the cradle to move around and wheel hop.

Yeah, I really don't get why they would not warranty them. Unless it will cause pre-mature wear to the arm bushings.

I called my dealer for an install quote and the shop foreman straight out told me to have it done at a performance shop to avoid warranty issues. Personally I think that if GM offers a performance part, it should be fully warrantied. I mean that is kind of the whole point of going with a GM performance part over an aftermarket company.

Unless you are looking for it though, the bushings are mostly hidden from view. To someone like me who values handling and stability, it was still worth it.

While you probably have a point with the arms and toe rods, I think the biggest culprit is the cradle bushings.

My plan was to do the cradle bushing and the arms, but I ran low on funds , so I decided to just start with the cradle bushings. I no longer feel a need to do the arms or toe rods. Just the solid pucks back there gave me what I thought was lacking in an otherwise great handling car.

My brand new Z does the same thing. It seems to be a common flaw. WOT does it every time.

It would be great to find a dealer-blessed, warranty-friendly, cost-effective solution for this issue. First world problems, but still!

I don't see how solid bushings could NOT degrade the ride and interior noise. You have less isolation. Rubber is used for a reason.

I had a 1SS 1LE and now a ZL1 1LE. Other than the improved stiffness and more planted and controlled rear end. There is zero difference in noise. Solid bushing dont do anything but help.

I’m not totally convinced that this straight line rear-steer-like phenomenon is caused by the rear cradle bushings. I ran my car at the strip on drag radials last month, and it was rock solid (best mph was 132.7). I’d think the sticky tires would have compounded the issue if that was the case.

The fact that it’s been reported by ZLE owners also backs that up. On my car, it really only seems to happen when there’s a small amount of steering angle present. Like making a lane change while WOT. Or accelerating along a gentle curve on the freeway. I still feel like it’s something with the E-diff calibration.

Not sure what to say, other than the engineers are not going to tune and install cradle bushings for no reason. It would be much easier for them to solid mount it, and call it a day.
