the lift height for the front should not go beyond 75 mm (3 inches) otherwise you'll be ripping the cv boots (at 4.5 inches/114.3 mm of lift height, i was ripping the boots at every 5000 km)...so try to reduce the spacer thickness..i think at 75 mm front lift, the stink bug effect shouldn't be much
you can then fit 33" tires and the look will be alot better!!
the rear coils (front lc coils) should be ok. they'll settle down to about 3.5"(90 mm) in a few months.
on the diff drop, try to check if you have clearance for a 50 mm of drop.
good luck!!
