They all have issues, it's just a matter of how bad.

The Superformance factory made two changes to address this rear mount problem. First was to go to 10mm bolts, up from the original 8mm bolts. Then they added sleeves to the frame member to keep them from collapsing. An improvement, but not a true fix.

Based on your chassis number, it would appear that you have the original 8mm bolt mounts on your car. At least for me, that would mean I would change those out first thing, as they have the greatest chance of failure.

If you still have the original springs, then they should be the 350 pound units. The 400 pound units will be stiffer. In my case I went with the 400, and now wish I had gone with the 450's. However I'm willing to sacrifice ride for handling. I also have the QA1 shocks set pretty stiff. Most of the suspension give is in the tires.

I have to add that everything I have bought from Randy at Cobra Valley has been first rate in regard to performance, quality, and instructions. Generally he is only a phone call away if you have any questions.
