BC coilovers aren't a no-name type coilover. They've been around for a long time and do great work.
As for a direct comparison vs other brands of C4 specific coilovers? I can't give a direct comparison.
After-all, I use a $140 set of motorcycle coilovers on my car haha.

The other thing to consider with coilovers is the actual perch and attachment design. Some are a lot better than others. And I would be super-careful about how the rears mount to the knuckle - that mounting ear is prone to breakage, and without any bracket then the spring can get in the way of trailing arms. With a bracket, you also increase the leverage arm on the mounting ear. Probably Van Steel is the best commercial option going right now, but I'm not sure any of them are truly satisfactory.

Check with Van Steel for C4 Coilovers. They have QA1's with single and double adjustable Coilovers. The application you are going to run will determine the spring rates you will want to use. Also, important to corner balance and set ride height once you choose rates. If just running on the street you could run whatever height you wanted.

I know this is an old thread but does anyone have the setup for rear coil overs.
I have installed new Bilsteins all the way around on my 96, that was a pretty penny, and a new composite rear spring and the ride is ok but it seems alot more "bouncy" than it should be. I am exploring coil overs for the rear as an option. And of course I need a project...

Not sure what "bouncy" actually means. If the ride is too harsh, then you need shocks with less damping rate. I would suggest Koni yellows or Ridetech HQs, both set at the lower end of the rebound rates. If your ride is oscillating too much after a suspension displacement, then you need more damping rate to control that. If you're hitting bumpstops, then something is wrong with your ride height or spring rate and you need to look at those things. Just switching from one form factor of spring to another isn't going to change anything. A spring is just a spring: it only has one job, and a monoleaf or coil do that job equally well. Coilovers can make sense in some applications: for example if you want stiffer springs than stock. But they aren't magic.
I installed Bilstein B6 and the new composite spring is rated at 228 pounds. I do have 1" longer rear bolts to drop the rear end a 1". I was thinking maybe I need to tighten the bolts to the stock length and see if that helps "tune" that back end a little bit?

When I first got my car back on the street the ride was harsh. It would bang really hard on any bump. It wasnt hitting the bump stops. The original rear spring had a split in it. I ordered and replaced it with a new one with stock ride. It is 1000 times smoother. But from time to time around my area on a road I have to drive on alot the back in feels like its bouncing, like it would with worn out shocks...I installed Bilstein B6 and the new composite spring is rated at 228 pounds.
