Ive just lowered my F1 on V3's! Most people on here have there standard 197's lowered on v1's. As you have the cup packs i reckon v3's would be your best bet, i have a feeling people with cup packs wouldnt notice the difference as much as the guys with standard suspension with the v1's. mine are set up stiff but the ride quality is still there. Not a lot of body roll, and really takes the bends amazing! It depends what you want from it tho, if you say its not really for lowering i cant recommend the v3's enough. Sure woody will tell you the same!! It really is the best thing you can do to the 197!!!! So easy to adjust everything as well!!
