Lowering Springs

Alright Guys n Gals..... I'm revisiting this again because I want a lower stance still but not paying $1000 ( Need $$$ for 410 gears ) for somebody to do it when I can. Will just need to get an Alignment when all done. Going with the SR Performance Lowering springs from AM for about $150. So with 1.5" drop ( after some drive time ) I think I have enough clearance. I'm running 245x45x19's. Lemme know your thoughts.
