I'm looking to upgrade my 3/1.5 Toytec leveling kit to the 3" Toytec Bilstein lift kit and was wondering if I will gain any additional lift in doing so? I have a 2004 v8 model, I realize that certain years have different fenders.

Current setup:
3/1.5 Toytec leveling kit + 1.5" RB body lift

Current fender measurements (ground to fender):
Front passenger: 39.25"
Front driver: 39.25"
Rear passenger: 40"
Rear driver: 39.5"

Future setup:
3" Toytec Bilstein lift kit + 1.5" RB body lift

Future fender measurements (ground to fender):
Front passenger: ?
Front driver: ?
Rear passenger: ?
Rear driver: ?

3" Lift W/ Bilstein 5100 Height Adj Coilovers FJ/4Runner

I will also be adding a new bumper in the future will the new coils help to handle the additional weight better than the leveling kit?

Thanks,
