I wanted to add this into to the forum for people who are looking for data.
I cut all 4 of my stock srt springs 3/4 of a coil off.
After a week of driving the car has lowered exactly 1 1/4" front and rear.
The ride feels abut the same which is stiff.
Hope this info helps anyone trying to make an edjucated guess on how much to cut to get the results they are looking to achieve.
