semi-coilover kits for C3

I know QA1 offers a couple semi-coilover kits for the front end of the C3 starting at about $350. Are there any other manufacturers with a similar kit? How many of you guys have one of these kits?

Seems like I read somewhere that the QA1 setup didn't allow enough adjustment to get the front of the car very low. I'm not sure what spring rate that was using.

The economy kit has 450# springs in it, but they also make 350# and 250# springs.

Read this thread on the other site (especially page 2):

Basically, the QA-1 springs don't work well. Speeddirect now has an adapter so that you can use standard coilover springs (more choices for rate and length) vice the tapered ones. Here is the info from their site:
Coil Over Spring Announcement:

We used to carry QA1 shocks and springs, however it has come to our attention that the springs supplied by QA1 have changed in design and do not fit in a Corvette spring pocket any longer. We have worked hard to engineer a solution to this problem and can now say that only SpeedDirect has the solution for the QA1 spring fitting issue. Our springs correctly fit in the upper spring pocket and we also now have a greater variety of spring rates available. Available rates range from 400 lbs to 1000 lbs. So if you are looking for a front coil-over setup for your Corvette we can make it happen.
If you already have a QA1 kit that is not fitting correctly we can provide the parts required to make it work right. You will need two springs (any part number that starts with SSSY, choose which ever spring rate you like) and you will need one spring adapter kit (part number 760-01000). That is all you will need to make sure your front coil over installs and functions the way it is supposed to. When using the correct springs that we provide, you will be able to lower the car to the ride height you are looking for and the spring will fit in the spring bucket without cocking over to one side.

Again, if you are ordering a Shark Bite coil over suspension kit there is no need to purchase this part - they are already included in the kit.
