Lowering a 2020 2SS with MRC

I recently switched from stock SS wheels/tires to SS 1LE spec wheels and tires, I now have a larger wheel gap, what is the best way to lower the entire car 1.0" to 1.5", I do have Magnetic Ride Control so not sure if that makes things more difficult...

What are my options (I'd like to do the work myself if possible)..

These look like the say they work with MRC, any issues? Does MRC need to be "recalibrated" or will it figure it out?

Lowering

I don’t know if you have to, but I had mine done when I installed the Eibach pro kit on mine its only a .700 drop according to the spec in the instructions.
This is how mine sits.

Do you have MRC and did you do anything with the MRC? If you could be far more specific that would be very helpful..

Lowering springs

Yes I have MRC and I just used a bidirectional scan tool and recalibrated them on level ground, I wasnt sure that I had to but I figured better safe than sorry seeing as how you have to disconnect the struts and the sensors from your car during the install Sorry for not being clear on that before.

What tool did you use to "recalibrate"??? I would really rather do everything myself (even if I need to buy a tool) than go to the dealer and try to explain what I need done...

Any very specific details you can provide would be GREATLY appreciated...

I had access to a Snap-On Versus pro D10, but I'm sure that you can use any quality scan tool to get the job done, it took two of us about an hour and a half to do the the job but we also used a lift and spring compressor for the front struts and did an alignment.

Any midrange scan tool will have manufacturer specific "special functions", typically accessible from the diagnosis page for each specific module, in this case, the MRC module. For example, I have an Xtool D8, and it also has this feature (ride height recalibration).

Has anyone used these springs from RST?

RST PX1 LOWERING SPRINGS
2016-2024 CAMARO SS & 2017-2018 CAMARO ZL1

https://www.phastekperformance.com/P...prings-px1.htm

They get really good reviews and offer a 1.25" drop, which is about the most of any of the springs for an MRC car... I like the Eibach springs but it sounds like the back would only drop about 0.40" with MRC which isn't worth doing...

Phastek said there is no recalibration of the MRC required, just need an alignment after installation...

Anyone with any experience with these springs? I'm not looking to slam the thing but after putting SS1LE spec wheels and tires on my non-1LE 2SS, I feel the wheel well gap is pretty excessive... I think this will fix it...

Any input is appreciated!

You are reading the specs wrong on the Eibach springs. For the SS non 1LE with MRC it will lower 1.1” all around. For the SS with 1LE it will lower .7 all around. A ZL1 is .4 all around. These are all different because all these cars sit different from the factory that is why the #’s change. I just did the Eibach on my ‘24 ZL1 and it is perfect. I also had them on my ‘22 2SS/1LE.

What size wheels and tires do you have on your car? I have 1LE wheels and tires (on a non-1LE) and my wheel gap is rather large, I think even with a 1.25" drop with the RST springs mine will still have more wheel gap than yours (or about the same but I don't think it will sit any lower)
