well you can do a fast math predication. your tire height(say 32) - 35 =3 but its half that so you gained 1.5 on the tires add the lift 2.5 is 4" add that to what you have stock. close anyway. Lifts vary, tires run short of listed in most cases, most 35"s are really 34.5. Many spring lifts are more than listed.
I net about 4.5 front and rear 4 on a 3.5 lift when it had less armor. now its 4 and 3.5 roughly.
