Dang man, I have always loved those wheels and almost bought a set! Looks very nice! As for the springs settling, you may get a little more out of it in the front but I dont think the rears are going to drop anymore than they already are. The front actually looks to me like it sits about where the 5658's should sit yoou. I know, by your measurements though, you should get more drop out of them, looks can be decieving but numbers are all that really counts! Looks damn good my friend!
