I used QA1 c/o shocks on my stock frame that I modded with the DSE c/o conversion kit. You have to get the narrow bearing kit from QA1 as well as the standard bearings are too wide for the DSE mounts. My car was pretty low and needed 8" springs....I had 7" springs in it when I sold my frame late last year.
The DSE arms should bolt right up to the Speed Tech frame. It may take a differant length shock though....give ST a call, they have all the answers and are great to deal with!
Hope this helps some!!
