After watching some videos it appears that my rears are not true coilovers and are in fact similar to the factory setup, with added adjustability.
As far as I know, this is the only option right now. Part availability for these cars isn't what it used to be. I try to buy stuff when I find it for that reason.Let us know how the install works out. I've been looking for a similar setup but there are not many options available anymore.
Check out SF Racing, they make adjustable coilovers for front and rear cavalier z24 models 88-94, here is the website link Chevrolet , I have these installed on my 92 Z24 front & back and they are very adjustable and lower more than typical lowering springs
No rush...I understand all to well. I'm in Minnesota.I can take some under car pics but the car is in storage now and it's snowing (I'm in WIsconsin), when I can get it out I'll get them to you
