After breaking my prototype Icon coilovers (and no time to finish the machining to correct the design flaw) I ran with old struts with unknown springs for over a year. I got sick of them, and was convinced I was losing at least 2" of lift from the saggy springs, I bought all new stuff. 89 springs (the stiffest OEM option), new Bilsteins, and Mark's best spacer. Put them in and got back 4" (!!!!!) of lift I had been missing. Front wheelwell lip now 40" from the ground again!
Longer report later (and in another thread) about the reason I didn't go back to my previous BDS spacers, and how much better I found Mark's design to be.
Installed
Nice thing about a body lift: You can install struts from the side without ever opening your hood and getting out the required step-stool.
