the correct spacers to use on the rear for the z06 are the FIFTEEN mm spacers, paragon makes some. by now many have seen pics of 20mm spacers on a Z and its awful, gonna destroy the fender.
you have to grind down the studs for the 15mm spacers but hardly any, and not even enough to encroach on any of the thread length. takes like 2 mins per wheel, cover stuff with a towel/tape/this/that and get 'er done =D

On a separate, but related note… guy on FB says he’s been working with Cicio regarding the possible development of spacers for the carbon fiber wheels. He should hopefully know shortly if they are a possibility. I know Paragon said they will not be developing spacers for that wheel.

well, no, because thats how math works. if the outer edges of your tires are pushed outward/outboard enough to where theyll contact the fender lip during suspension travel, then thats wrong.
whys it wrong? arranging things in such a way that they no longer properly serve their mechanical function is basically fuckboi status. thats like those harley guys that choose those dinky little helmets strictly based on how they look.
dont hate me, hate math.

I was a certified alignment tech in the mid '80s. Yes lowering requires re-alignment as it will likely affect both caster and camber, which then affects toe. Spacing the wheels should not affect alignment, but may transfer wear to the wheel bearings differently and over time may cause slightly advanced bearing wear...although I don't know what type of front bearings the vette has. I had to replace a lot of tapered bearings on old trucks when these guys would use 2" spacers on their lifted trucks.

To avoid the potential issues with the collars, does it make sense to just go with the lowering springs? Paragon offers them and achieves the 1" lowering. Seems pretty straight forward to me - I think the ride becomes 30% stiffer which I could live with opposed to a leaking break line.

I guess it depends how you look at it. To do the springs you have to remove all 4 shocks and mess with 4 mag ride connectors, which can be a PIA. The car will also be lower than some people want. With the collars you have the choice of the drop from 3/8, 3/4 or 1 inch, and you can adjust the rear coil overs up to 3/4 inch drop. Cost can also be a consideration, but either option can be the cause of a warranty denial issue if a shock or front lift actuator fails.

the correct way to check these things is to put it on the rack with wheel off, take the spring out and with a wheel sitting on the ground face down, measure from the floor (since that'll be the effective outside edge of your tire) to the wheel hub backface. then you take a magnetic articulated holder and position it so its at that same height and stick it on the hub. this way the tip of the mag block arm is where your tire sidewall would be. push the wheel assembly towards the sky and pray, easy with the spring out. if the tip of the mag holder passes safely behind the panel lip along its full suspension travel then we have joy especially since with camber you'll get just a liiiiiiiiiittle more clearance on top of that. everyone should have one of these mag block arms anyway (buy a Noga) for checking rotor runout and such.
but if you think your z06 with its track spring rate and the mag ride set to track is getting anywhere near fully squatting down in the rear you're smoking something good. =D
nice try though.

No issues with leaks etc using the collars - Did you do the work yourself - speed shop?
