Mine is down all the way on the stock bolts in back NO threads showing, I cut 2/3rd s off the front bushings in front with bolts all the way up. I used a keyhole saw to cut them It was hard but not as hard as taking everything apart . My wheel wells are 26&1/8 " from ground in front & 27&1/8" in back & the air dam is 2&1/4" from ground. bottom of car is 3 3/4" from ground behind front wheel & 4&1/4" from ground in front of rear wheel. Hope this helps.
I did mine without taking everything apart. Jack the front up, take off the wheels, use small hydraulic jack to lift end of spring to relieve tension on the bushings turn them down about half way & from under the middle of car you can see the bushings I used a keyhole drywall saw to cut the bushings its kind of hard, took about 20 minutes per side. I did it twice cut 1/3rd first It wasn`t low enough so I cut the 2nd 3rd off now its perfect! I recomend cutting 2/3rds the 1st time so you don`t have to do it twice!
