Been awhile since I posted and I finally just got my car back from having the BMS lockout kit installed. It's definitely a night and day difference, with no other changes. It had been squirrely right from the start, through winter and summer weather. I only ever really pushed it on dry roads, and I shudder to think how much worse it would have been on wet roads the way it used to behave. So I tried it today in 60F weather (it was raining when I brought it home yesterday) and it is definitely cured. Previously if I needed to pass someone on a 2-lane road, I'd have to pull out to the opposite lane and then roll into the throttle; otherwise you were very likely to end up sideswiping someone. It's a feeling I've never had in any car before, and I've had a 10 SS, a 14 Challenger SRT, a then a 16 SS. It just felt so uncomfortable under acceleration. I tried simulating a pass on an empty country blacktop and it was perfect; I hammered it, changed lanes at full throttle, and then eased back into my lane at full throttle, with only a very slight sense that the car was going to go where it wasn't supposed to, which I attribute to traction. But the uneasy feeling that must have terrified the previous owner and the old alignment guy is gone. So I want to thank everyone that helped me with my problem over the years I've had it. I was really just about to trade it off, but I thought I'd try one more thing. I think I can keep it now!

I had a little of that when I wore bushings out on the rear lower control arms. When I hammered the throttle, the back end would wiggle a little. Not enough to get out of control, but enough you could feel it in your "butt".

New ZL1 owner here. Got a 2024 A10 last September. I’m glad I found this thread. My car, while I like it, is squirrely AF. It’s not a traction issue although it is most prevalent under hard acceleration, including highway speeds.

The number one thing I do is get the tires warm first, here in Canada early morning when I take the car out, it can take half an hour.

I threw a bunch of recommended BMR suspension pieces at it, and it is pretty straight now. Ride is a bit harsh, but I can put my foot into it and not get violently sideways

By the way, is that "squirelly" feeling discussed here only a non-1LE ZL1 thing? I don't believe I've ever felt that with my ZL1 1LE, although I have had it before, way back when I had a (bought new) 2009 C6 Z06.
Obviously, I make sure my GY SC3R tires are warm enough, but yeah never had that sense of unsafe handling. So I'm quite surprised to hear about it here! It sure would make me want to get rid of the car if it ever did that. Geoff |

My ZLE had this issue in a bad way....basically on acceleration and holding the wheel straight, it would jump a lane, or on the track, head for the grass. Literally undriveable.
The fix was a retorque of everything in the rear of the car and going back to zero toe front and rear. The car is back to normal and now is as stable a can be. Ken

My factory alignment was all over the place so I took out toe, and thrust angle, and added some steer ahead, but you can't run big ass 325/345 tires on crowned or rutted roads w/o the car wandering around some.

Brand new, my ZLE was like this so I took it in for alignment and it wouldnt align to specs. I bought all BMR on car adjustable bars and that solved the problem. BTW, if using bars with a heim end, buy rubber boots to cover them or they will start creaking. Also, dont use petroleum based lube or it will swell the teflon lining in them also causing them to creak.

I'm surprised these companies dont give details about lubrication and dust covers on their heim ends. I thought you simply bolt em on and forget them because nothing in the instructions said otherwise. They started creaking so I used some lube on them but they progressively got worse and worse over a few months. Eventually, nothing stopped them from squeaking. When I called BMR and talked to a tech, he said to only use Super Lube silicone on them and buy the appropriate sized rubber boot from somewhere like Summit. I did just that on the replacement ends because if the same thing happened again, I wanted to have a leg to stand on. I'll say this though, BMR gave me a price break on all them heim ends. I think I wound up buying 12 altogether. |
