Lowering a ZL1

WillyZ83 · 08-15-2022, 10:45 AM

Which springs are the best when it comes to least ride quality change. I'm pretty picky about how the car rides. I'm wanting to reduce that fender gap some. What have you tried and how do you like it?

I've also put 5mm rear spacers and custom 11mm spacer in front w extended lugs to help with stance.

Eibach.

Based on my reading/research/feedback from other form members, the Eibach seem to be the best on paper, BUT there have been quite a few people who have experienced major spring sag very fast, this drastically effects ride quality and appearance since you will be squatting in the back if this happens.

BMR seems to be the way to go, the front rates are the same as OEM, the rears are not much heavier. They are linear rate springs that will not have the same sag characteristics as the progressive Eibach rear design.

On my personal car when I convert back to mag ride shocks, I will be giving the BMR springs a shot.

Thanks for sharing Zach, I haven't seen anyone post about this so I appreciate you letting us know!

Interesting, I haven't seen any reports of that...mine have worked as advertised, thanks for the heads up anyways.

Yes to both.

Will I rub on the rear for the occasional drag strip day? I’ll have a 305/45/17 drag rear on for those days. If go with the Eibach springs

Did most/all of you guys do the install yourself? If so, any tips or suggestions for those that may be considering the same? Thanks ��

For those of you who have a 2018-2022, how much lower did your car get lowered on the Eibach springs?

I ran the BMR as the eibach was a little lower than I wanted. Ride is great and lowered it just right.
