Default Lowering the rear of a C4

What is the lowest you can get the rear with simply bolts?

Low enough for the tires to scrub the plastic wheelwells.
The rear is simple to lower/raise.

Is 2 inches realistic with only bolts? I did a neat custom coilover conversion on the front end and the car has the abiliity to sit pretty much on the ground (in the front) if I want it to.

Do this on both sides.

This will give you the drop that your, I think looking for!!!

This is absolutely the WRONG way to do it, unless you just forgot to mention gluing on the aftermarket wedges. If you did it this way, your frame is sitting on your fiberglass spring.

Yeah that is a cut and paste straight from Digital Corvettes Forum.


Itchy, tell your mate to bring the car up to me on the sunshine coast, ill do it for him if he wants. (if your mate is who i think it is, it might be a fair drive for him though!! Does he live in QLD or Vic??)

I have the R-DRacing Cross Frame with the standard 91 Z-07 setup and I have to be reeeaaally careful and avoid most speed bumps and my X brace is welded which eliminated the bottom plate and bolt heads. Myself, I won't go any lower and my car autox's like a bandit already. For me the gain would be too small to see the benefit.
