Thanks for the linky...been to their site many times! lol I hope the DF's work out...what kind of struts does your co-worker have with those Df springs ? I was going to go with Tokico Illumina's
:edit: also, Dante...if you go to their site, and convert all the spring rates to lbs/in...that will give you a better idea of just how rough your ride is going to be.
