    Yes, aerodynamics. Secondly as noted by Alex MacDonald, VPE, as a GM vehicle it must meet every single GM standard, including such things as fording a certain depth of water, being able to drive though a certain height of snow, etc. Every vehicles design is a compromise. We get all around capabilities most sports car do not have.

    Nicely we as owners will have five different ways of addressing/reducing wheel gap in our Corvettes (all identified in my post # 11 above). I will be doing one of them but except for the last one I would never do (the coil cutting method), not sure yet which one I would use.

    Has Alex or any other GM engineer ever addressed why the corvette ships with such a large wheel gap?

    just curious since we know folks have been putting much wider tires in the C8 SR.
    Sorry I can not help you. When Alex was responding to why my specific question of how could I lower my Z06, he was definitely not endorsing my question/plan but answering it factually when he said the two suspensions systems are designed the same (SR and & Z06), so that if I were to choose to do what others have done with front lowering collars when equipped with E60 I could do that. Again I am stressing he was neither recommending I lower my Z06 nor saying that GM endorses my thinking. As to sizing we did not get into that; he was just saying that the Z06 did not have a new, nor unique suspension configuration — though as above he discussed that bushings, springs and MSRP software are all different. Are the control arms the same length, strength, and/or made of the identical steel were all questions I neither asked nor did he respond.

    Perhaps you could manufacture a key lock cylinder for the rear hatch?

    I don’t see why the collars wouldn’t work. I would think that it is the same lift system on the Z06. It’s the springs that I’m curious about changing.

    I used the cicio collars on my 2020 stingray that I no longer have. Just when I lowered the rear they told me I could not go any lower by spanning. Thus I would like to get a lowering spring instead of doing it that way.

    Per Z06 Vehicle Performance Manager Alex MacDonald, the Z07’s are 15% spring rate stiffer than on the Z06, though the perceived “seat ride stiffness” is only 8% stiffer on the Z07 than the Z06.

    The Z06’s springs are I believe 35% stiffer than the standard Stingray’s; I do not remember how much stiffer the Z51’s — though they are definitely stiffer than it too.

    As to wheel gap, each Z06 owner is going to have six choices, love it and or live with it as is; use wheel spacers that give perceived lesser wheel gap; get front lowering collars if you chose the E60 front lift option; rotate your shock shackles if you did not select E60 use reduced height aftermarket springs, or lastly the disastrous last one of cutting a coil or more off of OEM springs.

    ERGO five choices even if you do not want to “live with OEM wheel gap.”

    Reminder from the C7 generation, we again expect that the Z07 will be tougher to reduce its actual wheel gap than the Z06 due to its stiffer springs.

    I would guess there is a 2/3’s chance that as I am getting E60, that I would either get spacers or a combo or lowering collars and rotating the rear shock shackles. BUT, I am going to live with it, drive it thousands of miles first, and see what natural suspension settling does before I decide for ours.
