I recently installed a set of Vogtland Sport Springs on my 2014 V6 Vert. They where one of only a few that mentioned they could be used on a convertible. I chose them because they had the mildest drop of only 1.2 inches front and rear. My car dropped 1.9 in the front, and 2.0 in the back, and it rides on the bump stops. The stance is beautiful, but the ride is punishing on smooth roads, and unbearable on any kind of roughness no matter how slight. Its not about the stiffness, its that anything bounces me off the bump stops in the rear, which causes all kinds of freaky steering behavior. I am at a loss on what to do.

Does this look like a 1.2 inch drop?

I am seriously considering going back to stock, and just rocking the 4X4 look.

Try trimming the bump stops on both end. Don't remove them, just trim off no more than 1/2 the height. That will help the ride at the height you have now.

To boost the ride height a bit, use heater hose (5/8ths ID should do it) as a spring spacer on all 4 corners. Slip it over the end of the spring. Cut the hose so it covers just under a full wrap of the spring. It will add just about 1/4 inch more height. Use a length on each end for about 1/2. If that doesn't do enough, you will need a new set of springs from another supplier.

Last week I cut the bump stops a little less than half. This did improve the ride considerably because I had a little suspension travel.

This weekend I slipped some heater hose over both ends of the springs on the back. This raised the rear about 1/2 of an inch, but I think it will settle at maybe 1/3 of an inch.

I went for a drive on a road that I always avoid because of the waves, and bumps, and sinking pavement. The combination of your suggestions made all of the difference. I still have to do the front, but the rear remained planted, and secure. Thank you, thank you, thank you.

You are welcome!

A nice upgrade to consider for the future is stiffer shocks and struts. They will help this as well by damping the motion a bit more than the factory parts. I like adjustable dampers like Tokico Illuminas or Konis. That way you can tune then for the best results over the roads you drive. Plus you can crank them stiff for an autocross or a track day.
