Actually with 4-1/4 I still have plenty of room to drop the nose 2-inches without rubbing. That's next on the list for later this summer when I rebuild the suspension. I'll probably only go 1-1/2 to 1-3/4 though on the drop but only because I have clearance issues with the front spoiler and the dip on my driveway.
