I just did this, it's funny one bolt on each side slid right out while the other bolt was stuck. The rear bolts came right out. One front bolt took me 4 hours to remove and the other front bolt took me 6 hours. One came out the other I had to cut and drill.
As for cutting the coils I used a 4" angle grinder, use a cold wet rag or towel wrapped around where you are cutting so the heat doesn't move down the spring or it will weaken it. I cut 1 coil off the front and 1/2 coil off the rear, it lowered about 1" and now my floor jack don't fit under the cradle anymore.......oh well, looks cool.
I like the ride, but I've driven sports cars since I was 16 years old...
