Not sure if it was alignment related or tires.

Same here, I just installed the Nittos the other day, and the left to right is gone.

Rear axle alignment/thrust angle will do this too. Had this problem and fixing thrust angle cured it. This car is pretty sensitive due to high horsepower and wide tires.

A massive improvement IMO. The BMR stuff is ultra legit.

Could you share a list of those BMR stuff to change to make the suspension better?

Thanks

Search "BMR Read Cradle Lock Out" kit for ZL1 and you'll hit pay dirt. I'm putting this on my car with my coming build as it'll be 'mild' in the 700+ WHP category.

I am also putting in the lockout kit on my build. You only need to see those bushing made of hollow rubber to realize there is too much movement under hard acceration.

For ~400 bucks, totally a worthy investment!

I just went through the rear. I haven't gotten on it yet. I'm finally getting my alignment done today. I did ZLE bushings, and almost all BMR had for control arms/chassis: front cradle braces, upper/lower trailing, upper control, and tie rods - all rod-ends.

I can hear the difference, due to the rod ends and bushings, but it's not too bad. We'll see if it gets on my nerves, LOL...

Haha, that's what I said when I got the R888Rs installed, initially it didn't feel too bad, but some really bad frustration with the monster truck whine came upon me after a few days.

It's pretty much all in the rear. These are listed in importance from most important to least, IMO. Do the first 3, or you are wasting your time.

Cradle lockout bushings, or the more hardcore solid bushings.

New control arms and trailing arms

Toe rods

Cradle braces

Tunnel brace

Strut tower brace

Is this similar to the ZLE GM kit i have seen for sale?

Meaning ? You can hear vibrations? Noises from those parts? I want to make the car stiffer but not to the point i have noises.

I miss the ZLE feel but I don't miss the spring and struts.

Just trying to improve the car some without going all out and making the car unbearable

Thanks. What about the front?

I have all that, except the ZLE bushings. All I hear is some low speed creaking and groaning here and there. Not a big deal, considering the immense improvement to the car.

Up front I have the strut tower brace, and mid-chassis I have the - you guessed it - the mid-chassis brace.

I got them simply because I wanted them.

98% of the chassis improvement comes from all the stuff involving the rear cradle and rear suspension.
