Thanks for those measurements! I'll check them out against my car.Well I can say that I've never had any tire to fender clearance, either with my ECS flush kit or my current 18x9 ET45 and 235/40-18 combo with this setup.
Ground clearance...well you're lowering a sporty hatchback. I avoid any rises or ruts in the road like the plague because I did smack my subframe once on a 2-3" chunk of built up pavement because there was a bit of a dip right before it. I would have cleared it fine just rolling over it, but the suspension compressed. That's why they sell steel oil pans and skid plates. That's just an issue with lowering cars, not specific to these springs.
EDIT: To give a bit more information on FTG measurements, my car is:
FR: 25"
FL: 25"
RR: 25.2"
RL: 25"
For a suspension that has 20k miles on it and isn't adjustable that is amazingly even. Never checked it myself before but I'm pleased.
