ID:	160475 Since there are still no good solutions out yet to utilize the existing suspension on the non-Z51 C8 (ie lowering springs) I decided since my C8 was equipped with the front lift, I’d start with the Cicio 1” lowering collars. In the rear, since the non-Z51 shocks are not adjustable - but the Z51s FE3 shocks are - why not just try the logical choice and swap them out? Through GM they are cheap enough to try (approx $150/corner) and depending on how/if the ride changes substantially, we can always swap the front out as well - even though the likely scenario will be to go with a custom set of coilovers eventually anyways. I have new custom wheels been made so I wanted to get this worked out first because pretty much all of the 20/21” setups I’ve seen on stock suspension setting have looked like 4x4s, I had to tackle this first.

    Stay tuned! And also (finally) picking up my car from getting the first prototype exhaust completed from a local manufacturer in Houston tomorrow after about a month straight of R&D and can’t wait (will share more in a separate thread on that soon). Just the teaser sound clip I got today has me super excited...

    Take care and stay safe out there!

    Sounds like a plan. Do post that auduble video when you get your exhaust done, can't wait to hear it

          Message me your cell number and I’ll send you a teaser vid. Unfortunately can’t upload videos directly to here from my phone.

              I flipped it and reposted. Hope it shows up better.

              Many more projects than just these two... 😉

                  So what exactly did you do to lower the car? You got FE3 shock bodies that have the adjustable perches and you put your existing coils on them? And the Cicio lowering collar's for the front, I assume you have the front lift?

                    Correct all around. I haven’t been able to make the schedule work with my mechanic until next Tuesday so will post updates and any issues/etc once installed and tested. I know there is at least a couple others in the process of doing the same thing. One is swapping the front shocks also.

                      I'm curious to see how the FE3 shocks work with the softer FE1 springs and anti-roll bar, and how the front / rear balance turns out.

                        Is it not just possible to just get shorter coils and replace the stock coils to lower it? Or has no one come out with shorter lowering coils yet?

                          There are no lowering springs available separately at this time so this is a cheap “experiment” more than anything while we wait for other alternatives.

                            Exactly what we’re testing here. Going to swap one thing out at a time and see what the results are before changing the next thing.

                              We know the difference in spring rates from base to Z51:

                              Base - 180 f / 217 r
                              z51 - 226 f / 263 r

                              and that the rear bar in the Z51 is slightly larger by 2.7mm...

                              what we don’t know is specifics on the valving of the shocks. If they are what I’ve been told, they’re nearly identical minus the adjustability but we shall see. I’m ok with a slightly over-damped setup than the other way around.
